Nice iron sight
Installed this on a Varmint rifle build as backup to the scope. Not thrilled it doesn't have an elevation adjustment. Seems to work alright, but all all elevation adjustments are done at the front sight.

Nice sight for the money
If you are building a high dolar build this sight my not be for you. It doesn't have all the bells and whistles and it does on fold very low, but it holds its zero, mounts solidly and looks ok. I was quite surprised with the quality, I have two of them. These are not intended to be match sights, but for BUIS they are great. The finish is good and they look nice. They mount solidly to the rail and do not rattle or shake. The screws and threads are made well. They do not lock, but the detent hold them open solidly. Recoil has zero effect on the sights, they stay zeroed when shooting and return to zero when flipped down then back up. Expensive open sights have their place, but for me, these sights can shoot more accurately than I can, that's what my red dots or 1-6 scopes and 3-12 scopes are for, these are just fine for backups. If want to get the best sights available that's great, I have some expensive open sights too, Its your build and you have to be satisfied with it, put what you want on your rifle, have no regrets and don't worry about everyone's opinion. But if you are doing a budget build don't be afraid to buy these sights, they work well.

Great alternative for real people with budgets
Got it sighted in easy enough.. nice solid metal construction. Took some getting used to but that is jist cause im new to this style of rear sight. Did not wanna pay $60 for a magpul pop-up rear sight, so i settled for this. It drops down so i can use my red dot.. and i can easily co-witness my sights. Only weird thing is i had to turn the nob until the sight was sitting way left of center to align my shot at zero. But besides that, it works.. and i saved money.. and it doesn't appear as though itll break anytime soon. Worth it!

Put his on easily but agree with some it doesn't really 'lock' into the up position. It worked fine I was able to use it with my A2 sight but when making windage adjustments it did flip down once or twice but as I said it works fine. I don't believe it will flip down on it's own but a more secure lock-up would be good but for the money it is all I was looking for in a 'back-up' sight.

Bought this sight as a back-up on my 1st AR build, but ended up switching it to my 2nd build. This is a sturdy sight. Locking positions are crisp in the up or down. Sighted in #2 with A2 front sight at 25 yds, and was pinging steel at 100 after two adjustments. For the money, it's a good, tuff little sight.

I was not going to pay $50+ for a back up sight that was plastic. This thing is made of metal and gives me a little bit more piece of mind that if I run into something its not going to break. Huge locking lug though but all the better because you can torque it down really well.

Needed an inexpensive set of BUIS for my AR build, and was quite surprised at the quality. No buttons to press, just lift it up, it's spring loaded. Feels much more sturdy/secure than expected. I mated it with UTG MNT-751 front sight because I have a lower or not same plane gas block. It also is VERY nice.I would recommend it to anyone on a budget.

I got this sight for a AR15 to use in case my scope goes bad. It's well made and seems to work just fine. The sight stays down and requires a firm push to flip it up, it stays in place in the up position. Windage adjustments move nicely and click in place. The apertures are a good size for an AR I think, I like the two apertures for different ranges. Nice sight at a good price, I would buy another. It seems like a robust sight that will stand up over time.

This has stayed sturdy, mounted over around 500 rounds, and fulfills its purpose. Easily folds down to get out of the way of vision for my red dot. Hinge works fine, no spring but c'mon, it's the cheapest folder out there. If you're wondering 'Does this sight WORK TO HIT A TARGET?' Yes, it does. May be a bit bulkier and less flashy than competitors, but it allows you to hit targets with your rifle.

I use this with also it front sight, and it is easy to deploy. Just gotta get it sighted in. I use this sight combo on my AR-15, sig 516 and doesn't interfere with my red dot scope that I currently have on it. So if my red dot stops functioning, just flip these sights up and good to go. They use screw knobs for the bolts to attach it to the rail allowing for quick and easy mounting and unmounting. Would recommend if got the room and height clearance.

I bought this sight as a backup for my red dot sight. I don't have any problems seeing over this sight when it is folded down. It looks to be well made and sturdy. I haven't gotten to shoot with it yet, but should not be any problems. The windage adjument knob is easy to use. I like the markings on the base and the alignment mark on the sight so you can reference how far off center you are when making windage adjustments. Something the removable sight in the handle of my M4 didn't have.

I read the reviews, including the negatives and bought the sight anyway because of the price. I have not been disappointed. The sight appears to be well made and it's lower price is due to the fact that it lacks the bells and whistles of the more expensive sights. The sight mounted easily. I had to move the EOTech forward to install the UTG sight on the rail to co-witness well together. The sight easily flips up and locks and flips down and locks. The sight didn't vibrate loose from the rail or flip up or down due to recoil as a couple of others reported. It stayed in place in either position up or down. I first sighted the irons at 30yds and after printing nice groups, turned on the EOtech and sighted it in after flipping the UTG down at 30yds. Then I flipped up the UTG, lined up both sights and fired at 30yds with nice results. To summarize: If you want a BUIS on your rifle and don't want to spend a lot of money and have a KISS philosophy, this is the sight to purchase. From the positive reviews, it seems clear that many others had good experiences with this sight as I did.

I have mixed feelings about this sight. It's sturdy and strong, but does have a HIGH profile when folded down so count out using a scope mounted to the flat top with this thing on. The adjustment range is great and the markings are nice to reference to. I had to file the mounting surface to get a solid mate to the weaver on the flat top. When you switch the sight app, the windage clicks and changes position, but I haven't quite broke it in yet either. Guess I'm just used to AKs with one size fits all.

These are huge in the folded position. If you are trying to use it as a BUIS with an EOTech magnifier it just won't work. If you want some quality BUIS just spend the extra money and get some nice ones from Yankee Hill or Midwest Industries or whoever else you want. I mean they're a ton of companies to choose from. These are just a cheap filler.

This is a better buy than the more expensive rear sights. It doesn't have a pin that locks it into place like the Promag, so it can be folded down if you aren't careful when changing apertures. It does have windage marks (unlike Promag) and a wider sturdier base. Best BUIS with dual apertures overall , IMO.

I shot my flat top M4 .223 for whole weekend Appleseed event and never had one problem (Over 300 rounds fired). I wanted to improve my shooting with open sights and picked up a set of UTG front and rears. I greatly improved my scores over the course of fire. The unit clicks into the up position solidly enough - I highly recommend this unit. I would have given it 5 bullets had it not been as bulky in the folded position. I have to take it off to put my scope on or the rear bell touches slightly. Taller rings would solve that problem.

First time I used this sight I shot through the 10 X ring. However, the target was in the next lane over;-) I put my micrometer/protractor on this puppy and it is not precise.

It seems quality control is hit or miss there. Semper fi...

This is an ok BUIS. Its very sturdy, holds zero. Only cons are that the 'knob' is made out of a soft metal and the sight (in the down position) is still pretty tall, so much so that it is in the way of potential magnifiers/optics etc. Overall good buy though.

I got this sight because the Pro-mag I had my eye on doubled in price overnight (only to be listed at the cheaper price in the catalog sent with the order). This sight seems to be real bulky for a backup sight and is maybe 1/4' to 1/2' shorter when folded. On top of that the knob for attaching it to the rail is deceptively huge and really tacky looking, like something you would find on an airsoft gun.

This thing lasted exactly 2 rounds. First one was fine. On the second round and every other round thereafter the sight kicked back to the down position from the recoil. This was used on an M4 carbine type AR in 5.56 mm. This would be great for a .22 lr or an BB gun. But nothing with even moderate recoil. I send it back the day I got it.

This is a nicely made item, at unbelieveable price, works fine, all parts and operation are identical to the factory sight in the carry handle. The only complaint is that under heavy recoil from .50 Beowulf the mounting screw gets loose (I only tightened it by hand). Using a drop of blue (non-permanent) loctite fixed it. I don't ever need to mount/remount it because it is a flip sight.

I'd hope that after 300 rds. even a back-up sight would still function - I'm very dissapointed.You get what you pay for - if you plan on actually USING your BUIS, get something decent.

If you want a rear BUIS and don't want to pay the rip-off prices for a 'premium' version, this is it. Let's face it, anything over $50 is a rip-off for a BUIS. 50+ year old technology that you can mount to a picatinny rail. Doesn't seem to justify the prices that other companies are charging these days.

For the price, this rear sight is unbeatable. This works wonderfully as a co-witness setup with an EOTech. I had it zeroed in less than 10 shots. When the rear sight is locked in the upright position, there is absolutely no wobble. There is no knob to adjust the rear elevation, however, I knew that before my purchase and have it zeroed at ~200 meters. The windage knob clicks are crisp with no slack or play. It manages to hold a zero just fine. The flip-up 0-2 aperture permits firing in darker conditions. It also mounts very securely and tightly on my Stag-15 flat-top rail. This rear sight will definitely serve its purpose as a BUIS. The finish also matches that of my Stag. I shot a 239 out of 250 (with the 'expert' qualification being a score of 220) on a USMC rifle range (not with this rear sight), so I understand the importance of rock-solid iron sights. Some may criticize this sight because of the low price and the origin of the manufacturer, however, it works exceptionally well!
