Mfr. No.: 12996812-C

Current U.S. Army standard-issue backup rear sight for M4 carbines and M16A4 rifles flips up instantly at the touch of your thumb when primary sight fails or tactical situation makes iron sights preferable. Designed in conjunction with Picatinny Arsenal engineering staff and rigorously tested at Fort Benning and Aberdeen Proving Ground for robustness, ease of use, and effective targeting out to 600 meters. Detent-locking lever lets you quickly switch to one of eight range settings: 200, 300, 350, 400, 450, 500, 550, and 600 meters. Adjust windage easily with grooved, A2-style windage knob and position markers on the back of the sight for repeatability of settings. Bright, white, laser etched numbers and markers are clearly visible even in low light. Rugged machined steel construction ensures sight retains zero even under heavy, full-auto fire. Clamps securely to the rearmost slot of MIL-STD 1913 Picatinny or Weaver-style accessory rail on flattop receiver via simple but strong locking bar and bolt. Rounded corners and beveled edges further reduce danger of snagging on other gear when sight post is down. Regulates correctly with A2 front sight on any AR-15-style rifle or carbine; instructions included for adjusting front sight post height to set exact zero. Designed to co-witness with most non-magnifying optical sights.

Brownells USA A MUST HAVE! 23/07/2017

If you owned this product in the past and experienced walking pins and stripping... You unfortunately bought a generic clone. If it's the real deal, you'll notice it's rather expensive.

I love this sight. Very solid and locks down tight. Nice low profile in it's stowed positron. It'll never fail on you. This will survive WWIII and beyond. No gimmick or fancy features. Just robust, solid, true performance. My matech came with the picatinny logo and their name Laser etched on the right side by the windage knob.

Brownells USA Solid 02/02/2014

No problems with this guy. I had one a while back which had a spring problem...the sight wouldnt stay down in the "locked" position. Other than that Ive seen dozens of these things on issued M4's take a serious beating and do just fine. Like someone else said-this is not a match sight. Its a back up for a combat weapon. I can hit the 300m target on the pop up range all day with this sight.
