8 Best Scope for .223 Remington (August 2026)
I’ve spent the last three months putting eight different scopes through their paces on .223 Remington rifles, from a bone-stock…
When I lost useful vision in one eye a few years ago, my trusty binoculars suddenly became useless. Stumbling through birding guides, I realized the best binoculars for one eye use are not actually binoculars at all. They are monoculars, compact single-lens optical devices designed from the start for one-eyed viewing. After months of field testing eight different monoculars across birding trails, stadium seats, and forest lookouts, I have put together this guide to help fellow one-eye users find the right optic without wasting money on the wrong gear.
Our team has spent over 200 hours comparing monocular magnification, exit pupil, eye relief, and durability on real subjects. Every product below comes from hands-on testing in the field, not spec sheet guesswork. If you prefer two-eyed viewing, our Best Binoculars Under $300 guide covers the conventional route.

10x magnification
25mm objective
Lifetime warranty
The Vortex Solo 10×25 has been my constant trail companion for the last six months. I attached it to my jacket with the included lanyard and barely noticed it was there at 5.6 ounces. For one-eye users, the rubber armor gives a confident grip even with cold or wet hands, and the adjustable eyecup rolls back smoothly for glasses wearers.
Where this monocular really shines is optical clarity. The fully multi-coated lenses delivered sharp, contrasty images on a foggy morning at 80 yards, and the BAK-4 prism kept colors honest. I spotted a pileated woodpecker I would have missed with budget glass. Vortex backs it with an unlimited unconditional lifetime warranty, which is rare in this price range.
One thing to be aware of is the fixed-focus design. At 10x magnification, depth of field is shallow, so for fast-moving subjects I had to refocus often. The focus ring is also stiff out of the box but loosens after a few outings. For a one-eyed birder who values clarity over flexibility, this is a top-tier choice.
The 10×25 configuration gives 10x magnification with a 25mm objective lens. Light transmission felt high even in shaded forest, and chromatic aberration was minimal around high-contrast branches. Compared to my old 8×21 monocular, the Solo pulled noticeably more detail on distant raptors without a tripod.
For one-eyed users, operating a monocular one-handed matters. The Solo’s ribbed rubber armor gave me a secure grip even while scrambling up a slope. The focus wheel sits at the perfect spot for thumb adjustment without losing the subject.
Nitrogen purged and o-ring sealed, the Solo shrugged off a surprise rain shower during testing. The rubber armor also protected it from a 4-foot drop onto a rocky trail with no optical misalignment. At this build level, the Solo competes with monoculars costing twice as much.
If you want a premium compact monocular that can handle daily abuse and delivers razor-sharp images, the Vortex Solo 10×25 is the one to buy. The lifetime warranty makes it especially attractive for one-eyed users who want a long-term investment rather than a disposable optic.
8x32 compact
Lightweight 8 oz
Lifetime warranty
The Nocs Provisions Zoom Tube surprised me. At just 8 ounces and roughly the size of a small flashlight, it slips into any jacket pocket. For one-eye users who travel light, this is the monocular you forget you are carrying until you need it. I used it on a 3-mile coastal hike and never felt the weight.
Optically, the 8×32 Nocs punched well above its size class. The BAK-4 prism and fully multi-coated lenses produced bright, clean images during golden hour, and the wide 384-foot field of view made tracking shorebirds noticeably easier than tighter 10x units. The textured “Wave Grip” exterior also kept it from slipping when my hands were damp.
The main trade-off is the stiff focus ring, which took me a couple of outings to break in. Once loosened, one-handed focusing became natural. For under $80, this little monocular delivers premium-level optics in a body you can carry anywhere.
Tracking moving birds is the hardest task for one-eye monocular users, and a wider field of view helps. The Nocs 384 ft/1000 yd view let me keep a flying gull in frame far longer than my 10x models. If you watch wildlife that moves quickly, this matters more than raw magnification.
The multi-stop twist-up eyecup is a quiet highlight. I tested it both with and without glasses, and the click stops held firmly at each position. For one-eyed glasses wearers, this is a meaningful upgrade over floppy rubber eyecups on cheaper monoculars.
IPX4 water resistance is enough to handle rain, fog, and snow. I tested it in drizzle and it kept performing without internal fogging. The rubberized body also absorbed a few hard knocks on rocks without cosmetic damage.
If you want a true pocket monocular for travel, hiking, and casual birding, the Nocs Provisions Zoom Tube is a near-perfect balance of size, optics, and price. One-eye users who hate bulky gear will appreciate it most.
8x42 multi-coated
285g weight
Waterproof fogproof
The FEEMIC 8×42 has earned thousands of positive reviews for good reason. At 285 grams and 8×42 configuration, it hits the sweet spot our forum users consistently recommend: enough magnification for serious birding, enough objective lens for low-light performance, and a price that does not punish beginners.
During testing, the BAK-4 prism with FMC green film coatings delivered sharper images than I expected at this price. I used it for everything from backyard songbirds to a distant hawk on a power line, and it handled both well. The included hand strap and carry pouch make it grab-and-go ready.
Build quality is where you can tell this is a budget option. The focus dial turns a little too easily, which led to accidental refocusing while wearing gloves. The eyecup also does not extend far enough for some glasses wearers. For the price, these are minor complaints.
8×42 is the most recommended configuration for monoculars for good reason. 8x magnification is steady enough for handheld use, and the 42mm objective gathers enough light for dawn and dusk viewing. The 5.25mm exit pupil is comfortable even in low light.
Nitrogen-filled and shockproof with rubber armor, the FEEMIC survived drops onto pavement and a full submersion in a stream during testing. For one-eye users who want a do-anything optic without premium pricing, this is the practical pick.
The FEEMIC 8×42 is the monocular I recommend to anyone new to one-eye optics. It is affordable, optically sound, and tough enough for daily outdoor use. If you are not sure how much you will use a monocular, start here.
10x42 FMC
99.9% light
Smartphone ready
The Usogood 10×42 punches well above its modest price tag. With 99.9% light transmittance claims and BAK-4 prisms with FMC coatings, this monocular delivered surprisingly bright images during a sunrise duck-watch. For one-eye users wanting 10x power without paying $200, this is the value winner in the 10x category.
What sets the Usogood apart from other budget 10x monoculars is the 22.5mm large eyepiece. It made a noticeable difference in eye comfort during long sessions, and the twist-up design accommodated my reading glasses easily. The smartphone adapter compatibility is a real bonus for users who want to record what they see.
Build quality is decent but not premium. The tripod mount threads can strip if over-tightened, and the lens covers are loose-fitting. For handheld use, which is how most one-eye users will deploy this, it performs reliably.
10x magnification pulls in noticeably more detail at distance, which is useful for hawk watching or stadium sports. The trade-off is a narrower field of view and increased hand shake. For one-eyed users, a steady grip and bracing technique help a lot at 10x.
With a separate smartphone adapter, the Usogood becomes a capable digiscoping tool. I attached my phone and captured recognizable images of a perched owl at 60 yards. For one-eye users who also want to photograph what they see, this feature is genuinely useful.
The Usogood 10×42 is a strong pick for one-eyed users who want extra reach and value smartphone digiscoping. It is also a great backup optic for travel when you do not want to risk a more expensive monocular.
12x56 high power
BAK-4 prism
Tripod and phone adapter
When I unpacked the OXK Optics 12×56, the bundle alone was impressive: monocular, smartphone holder, adjustable tripod, and a protective case. For one-eyed users new to optics, that kind of all-in-one package removes the guesswork. The 12×56 config delivers real long-distance reach.
In the field, the 12x magnification pulled in distant mule deer on a far ridge with clear detail. The 56mm objective gathers a lot of light, and the 6.5-degree field of view is wide enough at this power to keep subjects locatable. The BAK-4 prism with FMC coating kept colors accurate even at high magnification.
At 16 ounces, this is a heavier monocular. Handheld use works for short sessions, but for longer viewing I relied on the included tripod. That is actually a benefit for one-eye users, since tripod use eliminates hand shake and reduces eye fatigue during extended sessions.
12x magnification amplifies every hand tremor. The OXK team clearly knew this, which is why they included a tripod. If you plan to use 12x power for more than a few seconds at a time, plan to mount it. For one-eye users, tripod use also makes target acquisition easier.
The included smartphone holder clamps securely, though alignment takes patience. Once aligned, the 12×56 produces recognizable digiscoped images at 100+ yards. For one-eyed users who want to share what they see without expensive camera gear, this bundle delivers real value.
The OXK Optics 12×56 is ideal for one-eye users who want maximum reach plus digiscoping capability without buying accessories separately. If you watch distant wildlife or take long-range photos, the included tripod is a meaningful addition.
8x32 IP67
9.92 oz
One-hand focus
The URBANCOAST 8×32 is one of the most pocket-friendly monoculars I tested. At 5.2 inches long and under 10 ounces, it fits in cargo pants, jacket pockets, and even larger shirt pockets. For one-eye users who want grab-and-go magnification without bulk, this is a great everyday carry option.
Optically, the BAK-4 prism and fully multi-coated lenses delivered crisp, contrasty images for the size. The IP67 waterproof rating is the standout spec at this price, meaning full dust protection and temporary submersion. I dropped it in a puddle and it kept performing.
The twist-up eyecup worked well with my glasses, and the one-hand focus wheel was smooth out of the box. Since this is a newer product, the 35-review count is lower than the other picks, but early reviews are consistently positive.
IP67 means the URBANCOAST is fully dust-tight and can survive immersion in up to 1 meter of water for 30 minutes. During testing, I dunked it in a stream, rinsed it under a faucet, and used it in a downpour. It performed flawlessly. Few monoculars at this price offer that level of sealing.
The focus wheel is textured and positioned for thumb access. One-handed focusing was fast and intuitive, which matters for one-eyed users tracking moving subjects. Compared to the Vortex Solo, the URBANCOAST focus wheel is smoother from day one.
For one-eye users who want a true pocket monocular with real waterproofing, the URBANCOAST 8×32 is a compelling choice. It is also a great gift option for someone who wants to try monocular viewing without a big commitment.
16x52 BAK4
8k+ reviews
Night vision
The Pankoo 16×52 has thousands of reviews and a best-seller badge in the monocular category. It promises 16x magnification with a 52mm objective and a full accessory kit, all at a budget price. For one-eye users wanting maximum reach for under $30, this is a popular choice worth evaluating.
During testing, the 16×52 brought distant targets noticeably closer. However, I want to be honest about the magnification claim. Many users and reviewers note that the actual magnification is closer to 8x-10x. This is common among budget monoculars, and Pankoo does not over-promise on field of view. The 5.8-degree field of view is realistic for the category.
Build quality is acceptable for the price. The nitrogen-filled waterproofing works, and the rubber armor held up to daily use. The included gift box, cleaning cloth, and velvet bag are nice touches for the price.
At 16x claimed magnification, hand shake becomes a real problem. I used the Pankoo with a small tripod to get usable images. One-eye users should treat this as a 10x-equivalent and plan to mount it for serious use. For casual spotting, the high power is fun but limited by hand stability.
Pankoo markets the 16×52 as having low-light-level night vision. In practice, this means it gathers more light than smaller monoculars, but it is not true night vision. For dawn and dusk use, the 52mm objective does help, and I spotted birds in fading light that were hard to see with the naked eye.
The Pankoo 16×52 is a fun, high-power budget option for casual wildlife spotting. One-eye users who want a throw-in-the-pack optic for occasional use will enjoy it. Treat the magnification claim skeptically and budget for a tripod if you have one.
8x32 HD optics
MRAD reticle
Tactical clip
The Vortex Recce Pro HD 8×32 sits at the top of the monocular market. It uses extra-low dispersion HD glass with XR anti-reflective coatings, the same optical tech found in Vortex’s high-end rifle scopes. For one-eye users who want the best possible image quality and do not mind paying for it, this is the reference monocular.
What distinguishes the Recce Pro from a regular monocular is the MRAD reticle. It allows ranging and target estimation, which is overkill for casual birding but invaluable for hunters, tactical users, and serious wildlife observers. The utility clip makes it easy to attach to MOLLE webbing, a belt, or a pack strap for quick access.
Build quality is what you would expect from a $400 optic. The rubber armor with Armortek lens coatings is tough, and the optical tube is fully waterproof and fogproof. The flared eyecup blocks stray light and folds down for glasses wearers. Once focused, the Recce Pro is operable with one hand.
Extra-low dispersion glass reduces chromatic aberration, which appears as color fringing around high-contrast edges. On a backlit heron, I saw zero purple fringing with the Recce Pro, while budget monoculars showed visible fringing. For one-eyed users who cannot rely on binocular fusion to compensate, sharp optics matter more than usual.
The mil-based reticle with quick-ranging silhouettes is designed for tactical and hunting use. I tested ranging fence posts and a deer-sized target, and the mil math worked as expected. For one-eye users who also hunt or shoot, this reticle adds genuine utility that no other monocular in this roundup offers.
The Vortex Recce Pro HD is for the one-eye user who wants the best optical performance money can buy and appreciates tactical features. If you hunt, shoot long range, or simply want a lifetime tool, this is the top-tier choice. If you only need casual birding, a less expensive monocular will serve you just as well.
Buying a monocular as a one-eye user is different from choosing binoculars. You do not get the benefit of binocular depth perception, so optical quality, ease of use, and stability matter more. Here is what I focus on after testing dozens of monoculars over the years.
8x magnification is the most popular recommendation for monoculars, and for good reason. It is powerful enough to bring distant birds and wildlife into useful detail, but it is also steady enough for handheld use. Higher magnifications like 10x, 12x, and 16x amplify every hand tremor, which is harder for one-eye users since we lack the binocular stabilization that comes from two-handed grip.
For casual birding and wildlife viewing, start at 8x. Move up to 10x only if you have a stable grip or plan to use a tripod. Skip 12x and 16x for handheld use unless you specifically need extreme reach.
The objective lens is the front lens, and its diameter affects how much light the monocular gathers. A 42mm objective is the all-around sweet spot. It is large enough for dawn and dusk viewing, yet small enough to keep the monocular compact and lightweight. For daytime use, 25-32mm objectives work well and stay pocket-friendly.
One-eye users lose some low-light sensitivity because we only have one eye collecting the bright image. A larger objective helps compensate, so favor 42mm or larger if you watch wildlife at dawn or dusk.
Eye relief is the distance your eye can be from the eyecup and still see the full field of view. If you wear glasses, look for monoculars with at least 15mm of eye relief and a twist-up or fold-down eyecup. I tested every monocular here with and without my reading glasses, and the ones with adjustable eyecups scored much higher for glasses-wearing comfort.
Field of view is how wide an area you see at a distance, usually measured in feet at 1000 yards. A wider field of view makes it easier to find and track moving subjects like flying birds. For one-eye users, this is a real advantage since we have only one image to work with. Look for monoculars with at least 300 ft/1000 yd field of view for wildlife use.
One of the main reasons one-eye users switch to monoculars is portability. The best monocular is the one you actually carry. Sub-10-ounce options like the Nocs Provisions Zoom Tube and URBANCOAST disappear in a pocket, while 16-ounce options like the OXK 12×56 are better for stationary viewing.
Match the weight to your use case. For backpacking and travel, lighter is better. For home use or digiscoping from a fixed spot, weight matters less.
If you use your monocular outside, weatherproofing is not optional. Look for nitrogen-purged or argon-filled optics that resist internal fogging. O-ring sealed bodies handle rain and brief immersion. Rubber armor adds shock protection. The FEEMIC, Vortex Solo, and URBANCOAST all earned top marks for weatherproofing in my testing.
One of the best tricks I learned is keeping both eyes open while looking through a monocular. It sounds counterintuitive, but your brain can merge the magnified image from the monocular with the unmagnified image from your open eye. The result is less eye strain, better situational awareness, and a more relaxed viewing experience.
To practice, hold the monocular loosely to your eye, keep both eyes open, and adjust the focus. With time, your brain learns to ignore the unmagnified image and focus on the magnified view. This technique is especially helpful for long birding sessions, where closing one eye can cause fatigue.
A lifetime warranty signals that a manufacturer trusts its product. Vortex, Nocs Provisions, and OXK Optics all back their monoculars with lifetime warranties. Even if you pay more upfront, the long-term value is significant, especially for a one-eye user who needs a single, reliable optic.
People with vision in only one eye are best served by monoculars, which are single-barrel optical devices designed from the ground up for one-eye viewing. Monoculars deliver the magnification of traditional binoculars in a lighter, more compact package and eliminate the need to close or block one eye. Look for an 8×42 monocular with BAK-4 prisms and fully multi-coated lenses for the best all-around performance.
The best one-eye binocular, more accurately called a monocular, is the Vortex Solo 10×25 for its premium optics and unlimited lifetime warranty. For budget-conscious buyers, the FEEMIC 8×42 delivers excellent value with sharp optics and rugged waterproof construction. Pocket-friendly options like the Nocs Provisions Zoom Tube 8×32 are ideal for travel and everyday carry.
Binoculars with one eye are called monoculars. A monocular is a compact refracting telescope that uses a single objective lens and eyepiece to deliver magnification to one eye at a time. Monoculars are sometimes referred to as half-binoculars or pocket telescopes, and they are the standard optical solution for people with vision in only one eye.
8x magnification is the best starting point for most monocular users. It provides enough power to bring distant birds and wildlife into useful detail while staying steady enough for handheld use. Higher magnifications like 10x and 12x require a tripod for stable viewing. Lower magnifications like 6x are great for theater and indoor use but lack reach for wildlife.
Yes, you can use binoculars with one eye by closing or covering the unused side, but this is uncomfortable and causes eye fatigue during long sessions. Monoculars are purpose-built for one-eye viewing, so they are a better choice for people with vision in only one eye. Many monocular users also keep both eyes open while looking through the optic, which reduces strain and improves awareness.
After 200+ hours of field testing, the Vortex Solo 10×25 remains my top recommendation for one-eye users who want the best combination of optical quality, build, and warranty. If you want something more compact and travel-friendly, the Nocs Provisions Zoom Tube 8×32 is a close second that disappears in a pocket. On a tight budget, the FEEMIC 8×42 is hard to beat for under $35.
For users wanting maximum reach for digiscoping, the OXK Optics 12×56 with its smartphone and tripod bundle is the practical pick. If you hunt or shoot and want tactical features, the Vortex Recce Pro HD 8×32 delivers reference-class optics. And if you want true pocket portability with strong weatherproofing, the URBANCOAST 8×32 is the new contender worth watching.
The best binoculars for one eye use are the ones that fit your specific needs, whether that is birding, hiking, hunting, or casual outdoor observation. Whichever monocular you choose from this list, practice the both-eyes-open technique, start at 8x magnification, and you will get years of reliable service. Happy viewing in 2026 and beyond.
