Switched from the polymer standard out there to this rugged sight. Round aperture is more traditional and provides much easier ability to sight in rifle when deployed. Locks in upright position no wondering if fully opened or not. Not cheap but you g...

This sight is nicely designed. It was easy to install and fit perfectly under my Leupold VX-III 2.5x8 scope. Snug and secure. Operates easily to flip up or fold down. Seems to be very rugged and I expect it to be durable. Look forward to getting more...

Most Recent Reviews One of the best BUIS available!!! by gunbutt, Verified Owner, October 31, 2015
I use the GG&G A2 Flip-Up BUIS exclusively on my AR-15s. It is very well made. The mount is rock solid and the sight zero is never affected by deployment/redeployment. I highly recommend this BUIS.

Product Info for GG&G A2 Iron Sight

The GG&G A2 AR 15 Rear Sight is one of the best-selling Back Up Iron Sights (BUIS) on the market today! These iron sights provide the operator with an easy-to-install and easy-to-operate low-profile BUIS that's ready to go when you need it. The GG&G Flip Up Rear Sight includes the all-important locking detent. Other features of these GG&G Rear Sights include a tactile ergonomic windage knob, a counter sunk crossbolt to eliminate the possibility of snags, and a streamlined body. The GG&G A2 Rear Sight is always at the tactical ready once placed in the up position. The flip sight cannot be folded down without depressing the spring assisted detent release button located on the left side of the sight base. This totally eliminates the possibility of accidentally lowering the sight.image

The GG&G BUIS Rear Sight can be used as a co-witness iron sight with most red dot sighting systems, as a stand-alone sight or in conjunction with one of our interface rails. Weighing in at just over two ounces, the GG&G A2 Flip-Up Sight features the standard military A2-style double peep aperture which allows for end user known point of impact. The sight has full windage adjustment with the tactile windage knob. One click of the windage knob provides approximately 0.48 MOA change when mounted on the M16A2E4 rifle and about 0.65 MOA on the AC carbine. Initial zero is set by adjusting the weapons front sight post. GG&G Tactical has designed these flipup sights with a low profile, so they are lowered they will clear most optics. The mount body and sight stem are manufactured from billet 6061 T6 aluminum alloy and Type III hard coat anodized in a non-reflective black mil-spec finish to provide combat durability. All steel components are black manganese phosphated per mil-spec. GG&G Folding Sights are the same back up iron sights used by elite armed forces and law enforcement teams world wide.
