"This is the same sight you can only find for $60- $100 more virtually anywhere else. It functions flawlessly, and maintains zero after a few thousand rounds, and after being removed and put back on. What more can you ask for in a sight."
– R Taylor
"I purchased one of these after seeing a similar one at a local show. The sight is very well made, looks great, fits and functions as it should. I would have given it a 5 star rating if I hadn't \"needed\" to add another small ball bearing to the sight base. When pushed clockwise the adjustable base should stop at the vertical post on the left hand side of the attachment base and then spring back about a 16th of an inch or so. Mine would hang up and not return to rest without a little help. I removed the adjustable base from the attachment base and added another small ball bearing to increase the spring pressure a bit. It now works perfectly. I am very pleased with this purchase."
"This really is a great deal for a BUIS. The quality is just like other big name sights but without the extra money. I spent the money I saved on ammo."
"Great product .. Man what a deal. These sights look as good or better than the one that cost $100 or more. Can't beat it. Looks great on my Rock river AR."
"Just received my order and I am impressed with these detachable sights, Im actually ordering several more as I type this. 3/6 marked on the ranging drum, 0-2 marked on the large hole flip sight, and the rear mounting allow for the addition of other sights (ie: Eotech,etc). These appear to be a(n) excellent value."
– Mr. D.
"Purchased this BUIS after spending all my money on an EOTech, can't go into battle with out a BUIS. I was just about to chop down my old carry handle into a BUIS when a friend told me about CTD and that he had seen a BIUS on the web. I looked at it and read the reviews and decided to purchase it. I am glade I did best 30 some odd bucks I ever spent. I would have given it 5 bullets but I had to pull out the sand paper and trim the side down to make if fit snug on my flattop so it would not slide back and forth, easy fix though. Beats paying $85-$100 any day.Peace to all but if not keep your AR handy."
– Mr. C
"This sight is worth every penny and then some. I have seen similar products during my search for fixed sights and this sight I feel matches higher priced ones. The quality is excellent, more than what I expected to be getting. I mounted it on my colt tactical carbine and use it for patrol. Dont spend the money on more expensive products, this sight is great!"
"great sight well worth the few bucks spent on it."
"Anything that can be removed and is essential should have a spare and this is what I bought this sight for. I pulled the rear sight and put this on to check it out.The workmanship isn't bad, no rough machining, it clicks like it's supposed to click...I'll have to take it to the range, but as a back up, it's gotta do what it's intended to do."
"I purchased one for my M4 to co-witness with my Aimpoint CompM2.I was extremely happy with the quality, it was better than I expected.I'm going to get another one for my next AR build."
"I was a bit skeptical at first... After a \"few\" rounds through my AR with it, I realized this is a good product. Held zero after several range trips, being bounced around the truck, and co-witness is great with SPOT and AimPoint."
"I agree with the rest of the reviews. Just as good as the expensive sights. No problems here and have recommended to alot of friends"
– SRT OFC
"Boutht this for my flat top DPMS to use when I remove my scope. It is easy to zero with positive clicking windage and elevation adjustments, but does not fit securly no matter how much tension is applied. I had to use some duct tape under the sight to make it stop from wiggling. It works and is a good back-up sight, but I would go for a carry handle sight if I had to do it over."
"Really good sight. I slapped it on, and it shot right on target"
"I purchased this sight for my latest build. I spent all my money on the rifle and needed a \"temporary\" sight until some came in. Well, I have to tell you this sight is awesome and right on the money. The accuracy is incredible for a sight this inexpensive. I was dead on at 75 yards as soon as I installed it. Well worth the money and as usual, CTD has the fastest shipping in the buisness, HANDS DOWN!"
"Just received this product. Fits tight on my Olypic Arms AR and it will compliment the High Viz fiber optic front sight post I just put on. Just what I was looking for the replace the carry handle sight. Cut out a lot of the extra weight and mass. Thanks."
"Don't even waste time with a more expensive sight. This fits very well on my dpms and lines up with my holosight, plus the variable reticle allows for full view forward on the wide peep. It is just very, very nice for the money and works very well!"
– eric m
"I spent a lot of money building my custom Wilson Combat AR, after all that I didn't want to spend too much for a buis. I was low on funds. I read the reviews and decided to try the sight out. I am very pleased with it. It fits very well, doesn't look half bad and functions as good if not better than half the buis I have used. This sight is a very good deal. The only issue I have is I would like to have a flip down sight to provide more view to my AimPoint. Don't get me wrong I still have a great view threw the AP with this sight, but I feel a flip down would be a little better. Still I give it five bullets. Try finding any other sight of this quality and function for this price, impossible."
"Nice craftmenship and went on nice and tight, but has yet to be tested. I will return with an update."
"Just recieved this sight today, extremely sturdy and no play/wobble to speak of. Mounted it on my Smith&Wesson M&P-15. Windage and elevation adjustment nobs are solid and have no play. Quality appears to be excellent in appearance, funtcion and design. Have yet to try it at the range. All in all and excellent buy, would highly recomend to anyone looking for a solid and reliable rear iron sight."
– The Brewer
"Haven't installed yet, but I am impressed with the quality of this sight so far. Hood & aperture are rock solid.Ordered the same brand front sight, looks great."
"I bought this because I wanted a BUIS and had no need for the detachable handle. It fit perfectly on my High Standard HSA-15 (M4) and is rock solid. I was amazed at the quality for such a low price. You simply cannot go wrong with this sight."
"Jut got my AR BUIS today..what a great buy. Fits the flattop of a AR15/M4 perfectly. Tight and holds zero very well on a my bushy. Absolute Co-witnesses the Aimpoint as well. Great buy..especially for $24"
"$25 for a sight(UTG) that cost 4x as much with someone else's name on it.This thing is \"Perfect\" I do not plan on having any optics on my AR so I did not choose the folding model. It will be the only sight I will use so I put a little Locktight on the threads, not that it needed it but just to be sure."
– Happy Customer
"Fast shipping and quality product for a great price. Real strong and sturdy. Fits perfectly. You can't go wrong with this sight. Go ahead and get it worry free."
"I drove all the way to Fort Worth from Houston to go to CTD and see the store in person one of the items I bought was this sight. Super heavy duty, well made worth every penny."
"This very well made rear sight. Attaches to rail tightly with no wobble and adjustments to elevation and windage knobs have no play in them at all. Do not hesitate to buy."
"You get what you pay for......except in this case. Inexpensive and the quality is high. The sight fit tight on my DPMS upper. Not a single problem after 200 rounds. Honestly, how often do you use the your $100 carry handle to carry your rifle? This is a nice, cheap alternative."
– Not a \"Leg\"
"Good for the money pin in bottom was loose but tightened up with a hit.Fit rail fine and tight."
"This is a decent rear sight, but for me, after 100 rounds, this rear sight loosens up and needs to be tighten. Also, at least on my rear sight, the iron site seems a little bent, which I am sure is affecting my accuracy."
"I recently built up two AR15's for a couple of friends. They decided on M4 style kits, so a rear sight was a neccessity. After looking around at what was available they decided on this sight. I didn't expect much and thougt they would be disappointed. When they arrived I was pleasantly suprised. They were very well made, both durable and accurate. I had no problem hitting targets 100 yards out. If you want an affordable backup rear sight, these are hard to beat."
"LOVE IT! Great rear sight. U have adjustments for windage and elevation, and u can cut down on the weight by not having the carrying handle on there. Good solution."
– the Zombie Killer
"I have an M4gery built on a Colt lower, Daniel Defense flat-top upper, and Colt barrel. I use a \"clone of Aimpoint\" red dot sight co-witnessed with iron sights. I had another brand of rear sight mounted on this gun, but it had to be positioned too far forward. And the gun just didn't look right with this set-up. So I took a chance and bought this \"cheap\" UTG sight. Very, very pleased. The sight locks onto the flat-top receiver and stays put. Color match is good, and lines flow into the receiver. I sighted it in late this afternoon at fifty yards. Once zeroed the 125 yd and 200 yd steel plates were no problem. Price may be low, but the value is high on this one."
– Silvertip from Indiana
"O.K. I ordered this rear sight because I wasn't sure if I wanted irons or optics so I didn't want to spend alot. Turns out I might just keep my Armalite the way it is now. This thing works great and shoots a pretty tight group right out of the box with no adjustments whatsoever. A great value and great item."
"No problems.... I\uFFFDve read the reviews and this is what I gather.The wobbling is caused when the clamp on the side of the site is up side down. Simply remove the site if it wobbles and rotate the clamp 180 degrees and reattach. The same is true for the front site one side snug one side is not. It\uFFFDs a very minute amount of difference but it worked on my Armalite.Don\uFFFDt tighten the screws to tight, they could start to strip, again no problems on my end.The elevation is a little sticky at fist \uFFFD. It WILL move\uFFFD\uFFFDif you do it right.I got both the front and rear fixed sites the work really well."
– Dan from Idaho
"Outstanding product for the price. Zeroed in at 25 yards on the first attempt. No problem at all with shooting tight groups at 100 and 200 yards. Great rear sight for the price and it is just the same if not better, in my opinion, than the higher priced rear sights that are out there. Quick shipping and great price. Thanks CTD!!!!!"
"Personally, I am an AIMPOINT COMP ML2 owner...who happens to buy this cheap rear sight as a co-witness, as an attempt. I had 700+ rounds through my comp2 and I don't think my AIMPOINT loosed its zero, which it doesn't and I'd be laughing my head off if it does. So my conclusion is: after 75 rounds this rear sight looses its zero. It performed well at first 30 rounds but given up after 50. For airsoft I supposed!"
"First off I know what I'm talking about, I build one of a kind components for space applications rockets and the shuttle. Don't waste your money, For sure the pin in the bottom will work it's way out eventually, the sight I bought lasted 3 rnds as well was crooked due to a casting flaw on the mounting surface on the bottom which also cause it to wobble, IT WASN't because the clamp was upside down. For the dude who thinks he is saving wieght this sight wieghs 3 times as much as a carry handle and besides the little amount of wieght your talking about is stupid thinking. The apature housing will move just from touching it and mine is also crooked to the sight body.If you think you have a good one just give it time it will not hold up in the long run, NO Way !. I just bought a set of mid west front and rear sights now this is a good high quality sight set. Remember a back up sight needs to work not fall apart and this sight will come apart just from using it, like I said mine took 3 rnds to fall apart and I promise you, IT will not last, It will break when you need it most. Anyone who thinks this is a good sight dosen't have a clue about building things from any alloy or metal."

"This sight appears to be well made, and durable which im sure it is. However about every two boxes (40 rounds) I found it loosed up. I applied blue loc tite to the threads and the next time I went to the range it worked for a couple hundred rounds before comming loose again. In addition to that problem with the adjustment all the way down I was still hitting about two feet up from a bench. Thinking it was me I had a couple of the old fellas at the range give it a go and the same thing. I guess ya get what ya pay for."
"If you move the sight up it gets loose and moves around. I have been using the front sight post to adjust elevation and keep this rear sight bottomed against its base; It has held zero using that method. If I just drop it on and tighten the thumb screw, a little bump will cause it to become loose on the rail. I have found I have to wiggle the sight around and continue tightening to make sure it's in just the right spot to get it to stay tight."
"As a novice shooter, this was easy to install and site in on my DPMS AR-15. It holds it mark after 300 rounds at 75 meters."
"bought both front and rear sights as back-up sights for my DPMS lo-pro classic, excellent quality. i can pull the scope off, install these sights and hit targets out to 500 yards with no problems or need for a re-zero. excellent!"
"I bought this for my su-16ca to put on the flat top picatinny rail, and disaster ensued. The sight was too high to match the front sights for my rifle, but I was willing to let that go and buy a higher front sight. However, when I tried to click the wheel to adjust the elevation, it was stuck from some kind of glue. I grabbed a wrench and unloosened the elevation wheel, but the teeth on the side of the wheel broke and grinded off, showing how weak the material to make it was. To add insult to injury, the sight itself was floppy and did not stay fixed firm enough on my picatinny rail, no matter how hard I screwed it in.Kel-Tec Su-16 owners, avoid this disaster. It's probably only optimal for Ar-15's."
– Homeland Defender
"I put this on my Doublestar and within 3 shots I had a good zero at 50 yards. It's not loose and the dials haven't broken or gotten stuck, I recommend."
"Installed thumb tight. Shot 300 rounds with a .22 conversion on AR-15 then placed the .223 bolt back in and fired another 150 rounds. Thumb screw was still tight and accuracy was acceptable. I would buy another one with out hesitation if I were building another rifle."
"I gave it 5 bullets because it is the best sight I've had for the money I spent. I put it on a picatinny-rail riser for my shotgun, and 30 slugs and skeet all day don't even begin to knock it out of alignment. The screws held fast with no loc-tite."
– tac danny
"Works better than I expected for the price. It hold nice and tight. Very noticable \"click\" adjustments. The only downside was the lack of instructions on how to get it zero'd in. I was on paper with my first shot at 100yds so I guess its not too bad and if I need any further help sighting them in there are instructions all over the net."
"Knowing how to use this sight would have helped the people that have complained about it. I read one review that the guy was apparently trying to use this REAR sight for elevation....after that didn't work out so well, he started using the front sight for it...like he should have in the first place. The sight is to be zeroed at 25M. The knob starts at 8/3....800M to 300M. (those irons specifically for the M4 will have a Z position) Put it one click past 8/3 (in the full down position, not the elevated). After you have zeroed it at 25M, set the knob to 8/3 and you are now zeroed for 300M. Notice how it counts up from 8/3 to 4 to 5 to 6 to 7 to 8/3? Once it is zeroed properly to 300M, you can adjust the zero for distances up to 800M by dialing the distance on the rear sight. (M16A2 max effective range on point target 550, area target 800M) Use the large sight for low visibility, otherwise, use the small \"peep\" sight. This sight does exactly what it is supposed to do- nothing more, nothing less. (and for the price, you can't beat that).Hope this helps those of you that gave this sight a low rating or complained because you couldn't get it to work properly."
"Being a Former Infantry Marine, I'm skeptical to use anything that hasn\uFFFDt passed the USMC test. But I could not be happier with this sight. I've put it through drop test not to exceed 9 feet, and it has maintained a BZO. Cheap or not, you can\uFFFDt beat this sight. Will definitely buy again for next AR."
"Rated this sight as a four only because I haven\uFFFDt shot with it yet. arrived at my house quickly and in good shape, mounted on my del-ton rail in seconds, extremely solid and easy mounting. All moving parts kind of stiff but would prefer that over too loose! So far extremely happy with this sight. don\uFFFDt waste your money on any other sight!"
"A great iron! It came zeroed for 300yrds. I recommend loctight for mount screws"
"Just assembled my first AR, slapped this little guy on and zeroed in 9 rounds. Burned 100 more rounds and held its zero; stayed nice and tight. Good job UTG!!!"
"Fit on a DPMS upper & a good finish match. Has held zero with no problem. A little stiff on elevation dial, but should get better with use."
"The sight appears to be decently made, and went right on. Shot about 40 or so rounds and got somewhat near the target center at 25 yards. Its not the fault of the sight but my eyes. I think that due to wearing bifocal contacts I can not focus front post and rear aperture together well. I even have some difficulty using a scope but that is what I will have to use on my AR. Again, this sight appears to be a good item."
"The accuracy right from the box was surprising. I figured Id have to spend an hour or so to get it sited in, but I only spent 15 min. and put 20 in at 90 yds. Left a nice 4 in cluster. Attached easily, the only negative was that after 20-40 rounds the thumb screw backed out and it slide off the rail, so definitely need to put some locktite on the threads. All in all for what it costs not bad at all."
"For what I paid for, I honestly can't complain...at all. Fit and finish is great. Seems to be well built, too. The windage and elevation knobs click is decisive and solid, as is the detent between the two sights. Fit solidly on my DPMS upper, with no wiggle or play whatsoever.I have not yet had a chance to sight it in, but am looking forward to it, and will probably report back in, too.CTD's oober quick shipping is great too. Ordered on Thursday night, got it on Saturday morning..."
"This reasonably-priced site is actually better quality than the factory carry handle sight that came with my Bushmaster AR. It's tough, tight, and snappy. I would recommend it to anyone interested in a cheap, reliable sight."
"This sight should not be used on a weapon with heavy recoil. I mounted it on a tactical shotgun and it broke at the rail mount after 20 rounds. It is made in China. This sight might be OK on a .223, but I wouldn't trust my life on it."
– Steve C
"Wow, someone took an A2 rear sight that's designed for the M4 in .223 or 5.56 and mounted it on a shotgun and then complained about the recoil issue - Wow. For those of us who purchased it for its intended use, I find it very dependable. Mounted it this week. I used a laser boresighter in my back yard to get the sights lined up and semi-zeroed. Took it to the range and after the first three round group, moved the windage four left and reshot. At 25 yards, I could cover the three shots dead center of the target with a dime and get five cents change. You need to know and understand the concept of the M4 or A2 type of battle sights. If you are not familiar with them, you should do some research online to get a good understanding of them before you spend a full day on the range without getting zeroed. And these sights are designed to be zeroed at 25 yards. For combat zero at 25 yards, you will be dead on at 250 yards. After zero, I took off these sights to mount the scope I purchased. I ended up not liking the scope at all, so I re-mounded these and confirmed zero. No shift in bullet placement yet. So I'm pretty darned pleased with these sights. As a matter of fact, I'm building three more ARs and this will be the iron sight I go to."
"Bought this and the UTG low-pro front for my Oly. Didn't even have to touch the windage adjustment to battle-zero. The best bang for your buck as far as stand-alone irons go, IMO."
– Dev The Dude
"Did exactly what I expected to do. Didn't take much to zero in. Will do until I can get optics I want or as backup."
