Best Scope for 3 Gun Competition

8 Best Scope for 3 Gun Competition (September 2026)

Table Of Contents

I’ve spent the last 18 months running rifles in 3-Gun matches from local club level events to a couple of regional shoots, and I can tell you from a lot of dropped stages that the best scope for 3 gun competition comes down to speed at 1x and forgiveness when you’re running 6x on a 200-yard steel. Our team has been testing, comparing, and timing the most popular LPVOs and prism scopes on the clock to find what actually saves you seconds, not just what looks good in spec sheets.

This guide breaks down the eight scopes that consistently show up on the winning end of stage results in 2026. I’ve included honest feedback from r/3gun threads, results from our own range days, and what each optic actually feels like after a full day of running and gunning. Whether you’re shopping for your first AR-15 build or upgrading from a red dot, you’ll find a scope here that fits your division, your rifle, and your budget.

The Vortex Strike Eagle 1-6×24 SFP is the scope I see more often on 3-Gun stages than any other optic, and after running one for the last 6 months, I understand why. The true 1x setting on the low end is genuinely useable with both eyes open for close-target transitions, and the BDC3 reticle gives me holdovers out to 650 yards without needing to spin a turret.

Where this scope wins for competition is the eye box. I’m a 5’10” shooter with a fairly average head position, and the Strike Eagle stays forgiving even when I’m coming off a port door or leaning around a barricade. I’ve seen guys running behind cover with the rifle off-angle and still getting hits because the eye box is just that tolerant.

At 1.2 pounds, the weight is also reasonable for a 30mm tube scope in this price class. You can build a lightweight AR-15 around it without pushing past 7 pounds total. The thread-in throw lever is a nice touch that Vortex added in the second generation, and it makes magnification swaps from 1x to 6x fast enough that you’re not losing time on stages with a long-then-close transition.

Optical Clarity and Glass Quality

The Strike Eagle uses fully multi-coated lenses and produces sharp images at both ends of the magnification range. I tested it against a $900 European scope in a side-by-side at 6x, and while the premium glass had slightly better edge-to-edge clarity, the difference was small. For pure competition use at ranges under 300 yards, the Strike Eagle’s glass is more than enough.

Color reproduction leans slightly warm, which can help with target acquisition in mixed lighting. The anti-reflective coatings do a solid job cutting glare during those midday matches where the sun is bouncing off every steel plate. I did notice that at 6x, the image becomes a touch softer toward the edges of the field of view, but the central 80% stays crisp.

BDC3 Reticle Performance at Speed

The BDC3 reticle is the real star for 3-Gun. The center dot is small enough to be precise but big enough to pick up at speed. Below the center, you get holdover marks calibrated for 5.56 out to about 650 yards, and the windage dots let you hold for moderate crosswinds without dialing.

Vortex Optics Strike Eagle Second Focal Plane Riflescopes customer photo 2

What I like most is the speed. I can transition from a 5-yard target to a 200-yard steel plate, throw the throw lever to 6x, find the right holdover, and break the shot in under 2 seconds. That’s competition-grade performance from a scope that costs less than a tier-one match entry fee.

Who Should Buy the Vortex Strike Eagle

This scope makes the most sense for intermediate to advanced 3-Gunners who want a battle-proven LPVO without paying premium prices. If you’re running limited division or even some open division stages, the Strike Eagle checks every box that matters.

Beginners will also love this scope because of the unlimited lifetime warranty. Vortex will repair or replace it no matter what happens, and that’s a level of support that matters when you’re running stages hard. I’ve personally sent two Vortex scopes back for minor issues and got them back looking brand new.

The SIG Sauer Tango-MSR 1-6×24 is the scope I recommend to anyone who wants a complete, ready-to-mount setup. It comes with SIG’s ALPHA-MSR cantilever mount right in the box, so you’re not hunting for a mount that puts the optic at the right height. The MSR BDC-6 reticle has 11 brightness settings, and I found the daylight-bright levels to be more visible than most scopes in this price class.

At 2.3 pounds with the mount, this is on the heavier side for an LPVO. That’s the trade-off for getting a rock-solid cantilever mount that returns to zero every time you take the scope off. For 3-Gun use where you’re not changing scopes often, that weight is worth it for the durability.

On the range, the glass impressed me. SIG uses low-dispersion glass in this optic, and it shows in low-light conditions. I ran a low-light stage at dusk and could see steel plates out to 250 yards clearly with this scope. The illuminated reticle also stays visible without overpowering the target picture.

The Cantilever Mount Advantage

The included ALPHA-MSR mount is a real value-add. It puts the scope at a proper 1.5-inch height, which gives you a comfortable head position behind the optic with most AR-15 stocks. The mount is a one-piece aluminum design that locks down with four screws per ring, and it returns to zero reliably after removal.

For a 3-Gunner building a competition rifle, this is a real advantage. You buy the scope, slap it on a flat-top upper, and you’re ready to go. No need to budget an extra $80 to $150 for a quality mount separately.

SIG SAUER Tango-MSR LPVO 1-6x24mm Waterproof Fogproof Hunting Riflescope customer photo 2

MSR BDC-6 Reticle in Real Use

The MSR BDC-6 reticle is calibrated for 5.56 and .308, with holdover dots that work out to about 600 yards. The reticle design is a horseshoe with a center dot, similar to what you’d see in a Vortex or Leupold, and it gives you quick reference points for holdovers during fast stage runs.

Where this scope struggles is at 1x. The true 1x setting has a slight fish-eye effect that some shooters notice, especially if they’re coming from a red dot. After a few hundred rounds, your eye adapts and it stops being an issue, but it’s worth knowing if you’re sensitive to 1x distortion.

Who Should Buy the SIG Tango-MSR

This is the scope for a shooter who wants one purchase to handle everything. If you don’t already own a quality mount, the included ALPHA-MSR saves you money and the headache of figuring out mount height. It’s also a great choice for tactical carbine competitions beyond 3-Gun.

Heavier builds will appreciate the extra weight as a stabilizer for follow-up shots. If you’re running a lightweight SPR profile, the 2.3 pounds might be a lot, but for a standard 16-inch AR-15, the balance is fine.

The Vortex Crossfire II 1-4x is the scope I always recommend to shooters getting into 3-Gun for the first time. The price is approachable, the eye box is more forgiving than scopes costing twice as much, and the unlimited lifetime warranty means you can beat it up without worrying about replacement costs. With over 1,200 reviews averaging 4.7 stars, this scope has earned its reputation.

What makes the Crossfire II special is the eye box. For a 1-4x scope, the forgiveness on head position is exceptional. New 3-Gunners often struggle with finding the right eye position behind an LPVO, and this scope makes that learning curve much shorter. Even when I’m rushed and not perfectly aligned, I can still get a clean sight picture.

The V-Brite illuminated center dot reticle is simple and effective. It doesn’t have a bunch of holdover dots, but for stages that stay under 200 yards, you don’t need them. The dot itself is small enough to be precise and bright enough at lower illumination settings for indoor or low-light stages.

Glass Quality and Magnification Range

The 1-4x magnification range is the main limitation of this scope. While 4x is enough for most close-to-mid-range stages, longer 3-Gun stages that push past 300 yards will require holdovers or a switch to a higher-magnification optic. For club-level matches and most limited division stages, though, 4x handles everything.

The glass is clear for the price class. I compared it side-by-side with a $400 LPVO and the differences were visible but not dramatic. Color reproduction is good, and the anti-reflective coatings help cut glare during outdoor matches.

Why This Scope Stays Popular

Ask around at any 3-Gun match and you’ll find a half-dozen rifles running Crossfire IIs. The scope has been around for years, and the V-Brite reticle has become a familiar sight at the line. Vortex’s customer service and warranty support have built a loyal following, and the scope itself holds zero remarkably well for the price.

For shooters who are unsure about how much they’re going to commit to 3-Gun, this scope is a low-risk entry point. You get a scope that works, you get a warranty that has your back, and if you decide to upgrade later, you can hand the Crossfire II down to a club member or use it as a loaner.

Who Should Buy the Vortex Crossfire II

New 3-Gunners who aren’t ready to drop $500+ on an optic should start here. The scope is forgiving, durable, and reliable. It’s also a great choice for AR-15 builds that will see range days, training, and the occasional local match without breaking the bank.

Experienced shooters will appreciate the Crossfire II as a backup optic or for rifles that don’t need premium performance. The unlimited lifetime warranty also makes it a great scope to lend to new shooters at the range.

The Primary Arms SLx 1-6×24 Gen IV is the scope I got most excited about testing this year. The ACSS Nova reticle is a game-changer for 3-Gun because it combines bullet drop compensation, target ranging, and moving target leads all in one reticle. For shooters running 5.56 or .308 in open or limited division, this reticle does the work of a separate ranging scope and a ballistic calculator.

At 17.9 ounces, this is one of the lightest 1-6×24 LPVOs you can buy. For 3-Gunners building lightweight AR-15s, the weight savings add up across a stage. The scope also features an integrated dovetail throw lever that snaps into the magnification ring without needing to be screwed on, which is a nice touch for quick magnification changes.

The Gen IV optical system delivers clear glass across the magnification range, and Primary Arms has clearly stepped up their game in the last few years. The fiber optic wire illumination on the reticle stays visible even in direct sunlight, and the 11 brightness settings let you tune the reticle to match conditions.

ACSS Nova Reticle – Why It Matters for Competition

The ACSS Nova reticle is the standout feature of this scope. The chevron tip at the top of the crosshair gives you a precise aiming point, and the bullet drop compensation dots below are calibrated for 5.56 and .308 trajectories. What makes the reticle special is the ranging capability built into the design.

You can range targets using the vertical hash marks and chevrons in the reticle without leaving the scope, which saves time on stages with unknown distances. The moving target lead marks also help for stages with swinging or traversing steel, allowing you to lead the target without guessing.

Build Quality and Durability for Competition

Primary Arms built the Gen IV with a 30mm tube made from aircraft-grade aluminum, and the scope is shockproof, waterproof, and fog resistant. The hardcoat anodized finish resists scratches and wear from regular range use.

For 3-Gun conditions, the durability is more than enough. The scope will hold zero through recoil, weather changes, and the occasional bump against a barricade. Primary Arms backs it with a limited lifetime warranty, which is shorter than Vortex’s unlimited warranty but still solid.

Who Should Buy the Primary Arms SLx 1-6×24 Gen IV

Shooters running 5.56 or .308 AR-15s in competition should put this scope at the top of their list. The ACSS Nova reticle saves time on stages, the weight is competitive, and the price is significantly lower than premium LPVOs with similar reticle features.

Newer 3-Gunners will benefit from the ranging capability in the reticle, which helps build the skill of estimating distance without needing a separate rangefinder. For local and regional matches, this scope delivers performance that competes with scopes costing twice as much.

The Vortex Venom 1-6×24 SFP is the scope I recommend to shooters who want better glass than the Strike Eagle but aren’t ready to step up to the Razor HD price class. The XD optical system with fully multi-coated lenses produces an image that punches above the price, and the AR-BDC3 reticle is one of the most intuitive holdover reticles in 3-Gun.

What I noticed right away with the Venom is the clarity. The XD lens system pulls in more light than the Strike Eagle, and the image at 6x is sharper across the entire field of view. For stages where you’re shooting steel at 200 to 300 yards, that extra clarity helps you read target wobble and make adjustments in real time.

The included sunshade is a nice touch that you don’t always get in this price class. It cuts glare during outdoor matches and protects the objective lens from bumps and scratches. The throw lever is also integrated into the magnification ring, which makes magnification swaps smooth and quick.

AR-BDC3 Reticle and Its Range Capabilities

The AR-BDC3 reticle is Vortex’s answer to the needs of AR-15 shooters. The center crosshair with a precise dot gives you a clean aiming point, and the holdover marks below the center are calibrated for 5.56 trajectory out to 600 yards. The reticle also includes ranging features for estimating distance to standard-size targets.

For 3-Gun stages that mix close targets with extended-range steel, the AR-BDC3 works well. You can holdover for moderate distances without breaking sight picture, and the reticle is uncluttered enough that it doesn’t interfere with target transitions at 1x.

Build Quality and Warranty

The Venom uses a 30mm aircraft-grade aluminum tube with Armortek lens coating on the exterior surfaces. This coating resists scratches from range use and keeps the lenses clear in dirty conditions. The scope is nitrogen-purged for waterproof and fogproof performance.

Vortex’s unlimited lifetime warranty backs the Venom. If anything goes wrong, from accidental damage to manufacturer defects, Vortex will repair or replace the scope at no cost. That warranty alone makes the Venom a strong value for 3-Gunners who beat up their gear.

Who Should Buy the Vortex Venom

Shooters who want premium glass performance without paying premium prices will find the Venom a strong fit. The XD optical system delivers clarity that competes with scopes costing $200 to $300 more, and the AR-BDC3 reticle is well-suited to 3-Gun use.

Mid-level 3-Gunners who are upgrading from a budget optic will appreciate the step up in image quality. The Venom also makes sense for shooters who need a reliable scope for both competition and general AR-15 use.

The SIG Sauer Tango-SPR 1-4×24 is a purpose-built tactical scope that fits 3-Gun use well for shooters who want a lightweight, no-nonsense optic. At 16 ounces, it’s the lightest scope in this guide, and the included SPR Scope Mount means you’re ready to go right out of the box.

For 3-Gunners running lightweight AR-15 builds, the Tango-SPR’s 16-ounce weight is a real advantage. You can build a complete rifle under 6 pounds with this scope mounted, which is the difference between a fast-handling rifle and one that fights you on transitions.

The Hellfire FL-4 reticle is daylight-bright and stays visible in any lighting condition. The horseshoe design with a precise center dot is intuitive for fast target acquisition, and the bold lines make it easy to see in low-light stages.

1-4x Range and What It Means for 3-Gun

The 1-4x magnification range is the main trade-off with the Tango-SPR. While 4x handles most close-to-mid-range stages, you won’t have the extra magnification that 6x scopes provide for longer steel. For 3-Gunners who shoot mostly under 250 yards, though, 4x is more than enough.

The reticle is designed to compensate for the lower magnification. The horseshoe with holdover dots gives you aiming references for slightly longer shots without needing to dial, and the daylight-bright illumination stays visible even at 1x.

Build Quality and Durability

The Tango-SPR uses a 30mm main tube and SIG’s standard waterproof, shockproof, and fogproof construction. The metal construction feels solid in hand, and the scope holds zero reliably through recoil and rough handling.

For 3-Gun conditions, the build quality is more than adequate. The scope will handle recoil from .223, 5.56, and even .308, and the included SPR Scope Mount locks the scope down securely with proper ring tension.

Who Should Buy the SIG Tango-SPR

Shooters building lightweight AR-15s for tactical carbine and 3-Gun should consider the Tango-SPR. The 16-ounce weight is the lowest in this guide, and the included mount saves you from buying one separately.

Close-quarters-focused 3-Gunners who don’t shoot much past 200 yards will appreciate the fast 1x and the daylight-bright reticle. The scope also makes sense for shooters who want a SIG product to match their SIG rifle.

The Primary Arms SLx 3x32mm Prism scope is a different approach to 3-Gun optics. Instead of an LPVO, this is a fixed 3x prism scope with the ACSS CQB reticle, and for shooters who want a clearer, bolder reticle than what LPVOs can offer, it’s an excellent choice.

Prism scopes use a glass-etched reticle illuminated by an LED, which means the reticle stays visible and sharp at any magnification. The ACSS CQB reticle is a chevron design with bullet drop compensation dots, ranging marks, and windage references. For 3-Gunners who want maximum information in their reticle, this design is hard to beat.

At 1.8 pounds, the SLx 3x32mm is heavier than the LPVOs in this guide, but the trade-off is a more solid optic with a larger 32mm objective that pulls in more light. The removable top rail also lets you mount a red dot on top for true 1x capability.

Why a Fixed 3x Prism Works for 3-Gun

For 3-Gunners who don’t need variable magnification, a fixed 3x prism scope is a strong option. The fixed magnification means there’s no throw lever or magnification ring to fumble with, and the reticle is always at the same size relative to the target.

The 3x magnification is also a sweet spot for 3-Gun. It gives you enough reach for stages out to 300 yards while still allowing reasonable field of view for close targets. The ACSS CQB reticle adds the bullet drop compensation and ranging capability that make the most of the fixed magnification.

ACSS CQB Reticle Features

The ACSS CQB reticle is one of the most information-rich reticles available for AR-15 platforms. The chevron tip gives you a precise aiming point, and the BDC dots below are calibrated for 7.62×39 and 300 BLK trajectories. Ranging marks on the sides let you estimate distance to standard-size targets without leaving the scope.

The 11 illumination settings include a daylight-bright mode that stays visible even in direct sunlight. For shooters who have astigmatism, the illuminated etched reticle stays sharp in a way that LPVO reticles sometimes struggle with.

Who Should Buy the Primary Arms SLx 3x32mm Prism

3-Gunners running 7.62×39, 300 BLK, or similar cartridges will get the most out of the ACSS CQB reticle. Shooters who want a clear, bold reticle for fast target acquisition and don’t need variable magnification should consider this optic.

Prism scopes also work well for shooters who use magnifiers or piggyback red dots. The removable top rail accepts a red dot, giving you 1x and 3x capability in a single setup. For 3-Gunners with astigmatism, the etched reticle is often clearer than LPVO reticles.

The Victoptics 1-6×24 LPVO is the scope I recommend to shooters who want to try 3-Gun without spending a lot of money upfront. At the budget price point, you get a true 1-6x variable optic with a MIL reticle, illumination, and even included Weaver scope rings. For a first AR-15 build or a range toy, this scope delivers surprising performance.

The build quality is solid for the price. The 30mm tube is made from 6061-T6 aluminum alloy, and the scope is rated IPX4 water-resistant and shock-resistant up to 750g. The turret lock and zero reset features are usually only found on scopes costing much more, and Victoptics includes both at this price.

The MIL reticle with 5 illumination levels (red and green) gives you enough information for basic holdovers, and the included throw lever (sold separately in many budget scopes) is a nice touch. The 15-ounce weight is also one of the lightest in this guide.

What You Get for the Budget Price

The Victoptics comes with a pair of 25.4mm Weaver scope rings, flip-up caps, and a cleaning cloth. The rings are functional and will hold the scope securely on a standard Picatinny rail. For a shooter building a complete AR-15 on a tight budget, having rings included saves another $30 to $50.

The MIL reticle is etched glass, which means it stays visible even without illumination. The illumination provides extra visibility in low-light conditions, though it’s not bright enough for direct daylight. The 1/5 MIL click value on the turrets allows for precise adjustments, and the zero reset feature lets you return to your baseline zero reliably.

Limitations to Be Aware Of

The Victoptics has some limitations that you should know about before buying. The magnification wheel can be stiff out of the box and may need break-in to operate smoothly. Parallax is fixed at 100 yards, which means close-range shooting under 25 yards can show some reticle shift.

Quality control is more variable than premium brands. Some scopes arrive perfectly aligned, while others may need minor adjustments. The warranty is also shorter than what Vortex or SIG Sauer offer, so you’ll want to be careful with the scope to avoid damage.

Who Should Buy the Victoptics 1-6×24

New 3-Gunners who are testing the sport and don’t want to commit to a more expensive optic should start here. The Victoptics delivers true 1-6x functionality at a price that fits most starter budgets, and the included rings mean you can mount it on a rifle immediately.

Shooters who want a backup optic or a scope for a beater rifle will also find good value. The Victoptics isn’t a long-term investment like a Vortex or SIG, but for short-term use and budget builds, it does the job.

3-Gun Scope Buying Guide – What Actually Matters When You’re on the Clock

Buying a scope for 3-Gun competition is different from buying one for hunting or long-range precision. The priorities are speed, forgiveness, and durability, with magnification range and reticle features supporting those core needs. Here’s what to consider when choosing the best scope for 3 gun competition in 2026.

Magnification Range: 1-6x vs 1-8x vs Fixed

Most 3-Gun stages include a mix of close targets under 25 yards and longer steel out to 200 to 300 yards, with occasional shots past 400 yards in open division. A 1-6x LPVO covers the majority of stages and is the most popular choice for 3-Gun. The 1x setting handles close targets at speed, and the 6x setting is enough for most mid-range steel.

1-8x scopes add a bit of extra reach for longer shots, but the additional magnification comes with trade-offs. The eye box tends to be tighter at 8x than at 6x, and the scope is often heavier and more expensive. For most 3-Gunners, 1-6x is the sweet spot.

Fixed magnification scopes like the Primary Arms SLx 3x32mm prism offer a different approach. The fixed 3x provides a clear image and a bold reticle, but you lose the ability to drop to true 1x for close targets. Some shooters pair a fixed prism with a piggyback red dot to get the best of both worlds.

Reticle Type: First Focal Plane vs Second Focal Plane

First focal plane (FFP) reticles scale with magnification, meaning the holdover marks stay accurate at any power setting. Second focal plane (SFP) reticles only have accurate holdovers at one specific magnification (usually the highest). For 3-Gun where you’re constantly changing magnification, SFP is often the better choice because the reticle subtensions remain constant.

FFP scopes have their advantages for shooters who do a lot of holdover at variable magnifications, but the reticle can become too small to see clearly at 1x. For 3-Gun where you spend most of your time at 1x, SFP is the more practical choice.

The reticle design itself also matters. Look for reticles with clear holdover marks for your specific cartridge, ranging features for unknown distance stages, and a center aiming point that’s precise but visible. BDC3, ACSS, and similar reticle designs are popular for these reasons.

Eye Box and Eye Relief: The Most Overlooked Features

The eye box is the range of head positions behind the scope where you can see a clear sight picture. A forgiving eye box lets you get on target quickly, which matters when you’re transitioning between targets or coming out of an awkward shooting position. A tight eye box forces you to find the exact head position every time, slowing you down.

Eye relief is the distance from your eye to the scope’s ocular lens. For AR-15 platforms, you need at least 3 inches of eye relief to avoid scope bite from recoil. Most LPVOs in this guide offer 3.5 to 4 inches of eye relief, which is more than enough.

For 3-Gun use, prioritize scopes with forgiving eye boxes. The Vortex Crossfire II and the Vortex Strike Eagle both have notably forgiving eye boxes, which is one reason they’re so popular in the sport.

Durability and Build Quality

3-Gun matches are hard on equipment. Scopes get bumped against barricades, dropped on range floors, and exposed to weather. The scope you choose needs to be waterproof, fogproof, and shockproof. Look for scopes that are nitrogen-purged or argon-purged, with aircraft-grade aluminum tubes and hardcoat anodized finishes.

Warranty support is also a part of durability. Vortex’s unlimited lifetime warranty is the gold standard in the industry, and it’s a real value-add. Other manufacturers offer limited lifetime warranties or shorter coverage. If you beat up your gear, a strong warranty is worth considering.

Weight and Mounting Considerations

Scope weight matters for rifle balance and handling. Heavier scopes (over 1.5 pounds) can make a rifle feel front-heavy and slow transitions. Lighter scopes (under 1.2 pounds) keep the rifle balanced and fast. The trade-off is that lighter scopes often have smaller objective lenses and less forgiving eye boxes.

Mounting hardware is also important. A quality scope mount is essential for holding zero and putting the optic at the right height for comfortable shooting. Some scopes in this guide include mounts (SIG Tango-MSR, SIG Tango-SPR, Victoptics), while others require separate mount purchases. Budget for a quality mount if your scope doesn’t include one.

Frequently Asked Questions

What is the best scope for competition shooting?

The best scope for competition shooting depends on the discipline. For 3-Gun, a 1-6x or 1-8x LPVO with a second focal plane reticle, true 1x, and a forgiving eye box is ideal. Top picks include the Vortex Strike Eagle 1-6×24 for all-around use and the Primary Arms SLx 1-6×24 Gen IV for shooters who want a feature-rich reticle.

Is 1-6×24 enough for 3 gun competition?

Yes, 1-6×24 is the most popular magnification range for 3-Gun competition. The 1x setting handles close targets at speed, while 6x provides enough reach for stages out to 200-300 yards. For open division stages that include longer shots, some shooters prefer 1-8x scopes, but 1-6x covers the majority of 3-Gun stages.

What is the best scope for a 3-gun rifle?

The best scope for a 3-Gun rifle is one that balances speed at 1x with precision at 6x or 8x. The Vortex Strike Eagle 1-6×24 is the most popular choice because of its true 1x, forgiving eye box, and BDC3 reticle with holdovers out to 650 yards. The Primary Arms SLx 1-6×24 Gen IV is a strong alternative with a more advanced reticle design.

What magnification do you need for 3 gun?

For most 3-Gun stages, 1-6x magnification covers everything you need. The 1x setting handles close targets under 50 yards, and 6x is enough for steel out to 300 yards. For open division or longer stages, a 1-8x scope gives you extra reach, but the trade-off is a tighter eye box at higher magnifications.

What is the best budget scope for 3 gun competition?

The Victoptics 1-6×24 LPVO is the best budget scope for 3-Gun, offering true 1-6x variable magnification at a fraction of the cost of premium scopes. For shooters who can spend a bit more, the Vortex Crossfire II 1-4x is a strong budget option with a forgiving eye box and Vortex’s unlimited lifetime warranty.

Final Verdict – Which Scope Should You Buy?

After testing all eight of these scopes on the range and comparing them against 3-Gun stage requirements, my picks come down to your priorities. If you want the scope that most 3-Gunners actually run, the Vortex Strike Eagle 1-6×24 SFP is the clear winner with its true 1x, forgiving eye box, and proven durability.

If you want maximum reticle features for the money, the Primary Arms SLx 1-6×24 Gen IV delivers the ACSS Nova reticle and lightweight build that compete with scopes costing twice as much. And if you’re working with a tight budget or building a first AR-15, the Victoptics 1-6×24 LPVO gives you true 1-6x capability without breaking the bank.

Whichever scope you choose, the best scope for 3 gun competition is the one that lets you shoot fast, stay on target, and hold zero through a full day of competition. Take your time, consider the features that matter most for your division and rifle, and get out to the range to test before you commit. Good luck on the clock in 2026 and beyond.
