  • A VERY NICE RED DOT SIGHT FOR YOUR FIREARM!!! Read on...
Color: Black
I bought this sight in 2022 and never looked back. An EXCELLENT CHOICE with versatility that's second to none, and better than many with it's Dot, Circle/Dot, Crosshair/Dot and Crosshair/Circle/Dot combination of sighting pictures/reflections! As well, you get your choice of 5 different brightness settings in either red or green. Settings low enough to see any of them at dusk/night clearly, to super bright so you can see them in the sun light! Runs on a CR2032 battery sold everywhere... and my original btty that came with it 3 years ago is still powering it as bright as the day I got it! It's sat for several months at different times in the off position and has never failed once. I see a LOT of bad reviews claiming folks have zeroed it in with a laser bore/chamber sight and then claimed they couldn't hit the broad side of barn. I think MOST of the complainers have no clue how to check their laser bore/chamber zeroing equipment for true zero and that is the reason they can't hit the broad side of a barn with their firearm!!! Just because it says "Bore Sight" for sighting in your scopes and red dot or iron sights etc DOESN'T MEAN *it* is properly zeroed in to begin with. Why do you think you must zero in your scopes or red dot sights? Because many aren't truly zeroed in at the factory after how many thousands pass down the line! Think about that for a minute relative to laser bore-sighting equipment. Do your home work guys and gals! Learn how to check your test/alignment/zeroing equipment to be sure it's at it's optimal best before you go blaming another piece of equipment that relies on *that* piece of equipment you're ASSUMING is perfect in the first place! This red dot sight is very accurate once setup and zeroed in with properly tested sighting-in equipment that's truly zeroed before hand. Almost *every* reviewer that's complained admits the sighting/zeroing process is repeatable. Doesn't that tell you something!?!? This sight is no different than the $200-400 sights in quality and craftsmanship, except those manufacturers have taken the time to be sure it's zeroed in at the factory level so you'll PAY their asking price as they constantly/consistently check their factory testing/zeroing equipment over and over. That costs time and money that your paying extra for with VERY few exceptions on the market. Those exceptions are generally red dot *scopes* with coated optics that magnify etc. This red dot sight as others have corrected reviewers about, *IS NOT A SCOPE*! It's a clear piece of ground glass that the internal light producing the red dot you see is reflected on! Therefore it's a sight that serves the same purpose as iron sights. I own three different CVLIFE brand sighting pieces of equipment, 2 rifle scopes and this red dot sight. Every one of them are high quality sights for the money that do what they're designed to do if/when properly set up. No they're not $5k Zeiss scopes etc, but as others have said, you get what you pay for as a rule of thumb. But I'm here to say their ARE exceptions, and CVLIFE is one of those exceptions IMHO. One CVLIFE scope I own is mounted on a 5.56 AR-15, one on a .458 SOCOM AR-15, and this red dot currently on a 12GA bullpup shotgun with a 20" smooth bore barrel that puts slugs inside a 3” circle at 50 yards all day long! For what they cost, I can't say enough good about CVLIFE products at this point. I'm a private individual that was not promised, given, or-coerced in any way for my 2¢ worth of opinion stated here. I payed retail price for these out of my own pocket just as most of you have and I'm *NOT* affiliated with CVLIFE, or any other company for that matter. This is MY own 2¢ worth of opinion. Take it for what it's worth. I'm just tired of people bad mouthing things because they don't know what they're talking about, doing, or even how to do things correctly. I see this mentality *everywhere* and just got tired of it, so I stated my opinion! You don't have to like or even agree with it! ..but if you've read this far, then I thank you for your time and interest. So there you have it! Ignore those that don't do as noted above and have nothing good to say because of their own lack of knowledge about what they're doing, their own shortcomings, or how to do things properly. This is a good red dot sight when properly adjusted and set up with properly tested and known good setup equipment. Get someone that knows what they're doing to set it up if you don't. Not everything's perfect in life and their are flawed units out there, but far *more* than 16k people bought this red dot sight and folks are still buying it. They can't all be wrong! ...and only 16k of 'em left a review! Go figure!!! Get yourself one or two of these sights and get it/them set up properly! I promise, you won't regret it. ...Enjoy! ... show more

  • Great price feels and looks like quality
Color: Sand
I ordered this red dot to put on a 450 bushmaster gun is not finished yet so I can’t say it will hold a zero but it feels good in my hands it’s clear the only reason I gave it a 4 stars and not 5 is because I don’t know if it will hold zero with this 450 if it does I come back and change my rating on it but should be an awsome optic so i finally got around to mounting scope went to sight it in got it to zero and hold up to the 450 bushmaster I’m happy with it if it holds zero with a 450 bushmaster put it on everything from 450 down ... show more

  • Sometimes you get chicken...sometimes you get feathers.....then you're back with chicken!
Color: Black
Not sure who is the blame. Ordered one of the sights and was very happy with the product. Good product at a good price...I thought. Came in nicely padded box with batteries and instructions. Put it on an AR 22 rifle for a granddaughter, right handed, left eye dominant, so figured a better targeting device for her. Liked it so well ordered another one but as soon as I opened the shipping box, I had a sinking feeling in my guts, Wrong brand box for packaging, sight doesn't fit properly so had a sheet of ruled paper torn into three pieces then wadded up as packing material. No batteries, though did have the instructions. Tried battery I had on hand, nothing. Bought some new 2032 batteries, put them in and nothing on the screen at any position. Tried another battery, nothing. Also noticed that the selection knob for the crosshairs was so loose, recoil would have moved the switch position. Probably a returned item just resold without checking out the product first. $ad state of marketing. Review update, 03-03-26 Not sure if this is the right way to amend a review so here's for the best...CVLIFE contacted me after the review saying they would send me a full refund. As mentioned in the original review, the sight was in a an anomalous box with none of the regular original items. Since I was happy with a previous sight I had bought, I wanted a sight, not a refund. I asked for a sight instead of the refund and I got the new sight. It came in and I checked it out and all is good with it. It's on a rail right now. My next sight of this type will be through CVLIFE again. Glad CVLIFE contacted me on here. ... show more

  • Crystal Clear Reflex Sight for Range and Field
Color: Black
Crystal Clear Reflex Sight for Range and Field I mounted this CVLIFE reflex sight onto an AR platform, and it impressed me right out of the box. The sight itself feels solid and well-built, with a snug fit on the Picatinny rail—no wobble once tightened down. Zeroing it in was quick and painless; after about 10 rounds it was locked in, and it’s been holding zero nicely through multiple range sessions. The reticle is bright and easy to pick up, even under direct sunlight. I like having both red and green options since lighting can vary depending on the environment. The four reticle shapes are a nice bonus—circle dot, cross, etc.—and switching between them is simple. Eye relief is unlimited, which makes target acquisition fast and intuitive. A few practical notes: the adjustment knobs have decent tactile feedback, but they’re a bit small if you’re wearing gloves. The included CR2032 battery isn’t hard to replace, though I’d recommend keeping spares in your range bag. The sight window is on the smaller side compared to high-end optics, but for the price point, it’s more than adequate. I’ve run about 300 rounds with this mounted, and so far it hasn’t loosened or lost zero. The aluminum housing seems durable enough to take normal knocks and bumps, though I wouldn’t abuse it like a duty-grade optic. For casual target shooting or plinking, this delivers more than I expected. Bottom line: A great budget-friendly reflex sight that holds zero, offers multiple reticle options, and makes target acquisition fast and fun. Perfect for recreational shooters who want a reliable optic without breaking the bank. ... show more

  • Pleasantly surprising budget optic
Color: Black
I'll be honest, I didn't have high hopes for this little red dot, and was pleasantly surprised. A friend of mine wanted to shoot my AR-9 PCC, but I lent my primary optic to another friend in need. Not wanting to let him down, I had this CVLIFE optic overnighted, and for an optic that was $27 door-to-door, I'm very happy with it. For indoor range usage, I found the glass to be of acceptable quality and clarity for my purposes. I do appreciate the red and green dot options. It's nice to have brightness options as well for both colors. When I got to the range, I was hitting a little left, but still level, so I adjusted the optic with the included tool to center things. After that quick range zeroing, it worked out great and found it to be exactly what we needed for the day. Time will only tell how battery life is and if it maintains its zero. I really like that CVLIFE added a lens cover for the optic to protect it. ... show more

  • Ok for the price
Color: Black
Feels and looks decent enough. The knob I use to control the brightness and color is completely off (like a dim red dot shows as bright green and you have to turn it to green medium to turn it off) and the red light is too dim to use outside.

  • Very well made unit - I am impressed with the quality of this optic for the price.
Color: Black
This is a good quality and well built red/green dot sight. I am using it on a simple .22 rifle and it has performed well. The optic is clean and the illuminated dot is bright (adjustable) and easy to see. I was able to zero in this sight very easily and I am impressed with the build quality on this unit. I am using this sight on a very basic rimfire build that is not taking a beating from high energy cartridges so I cannot speak to it's durability for those types of applications but it is more than adequate for a rimfire rifle. It seems to hold zero very well. The screws and machining on the unit are well done and the quality control seems to be good. They provide a glass cover which is nice for a pest control farm rifle that gets beat-up a little bit. I recommended this optic to a friend who is like me and older and wanted to get a red/green dot sight now that our eyes are not as sharp as they used to be. All in all, I am very impressed with this optic for the price. I remember when sights of this quality and function were over $300 and that was honestly not that long ago. This review is written by a person who lives in the country and uses this sight on a rifle to control pests over a vegetable plot and around a workshop. ... show more
