Rock solid mount have had off and on several times while trying diffferent set ups on this rifle.While everything else has changed up to it's final config. The zero never has!The reversable throw levers are a great feature as well. I flip mine forward for more CH room and scope throw levers.

This is my third American defense qd mount. This mount fit perfectly on a primary arms 3x prism. Very impressed with the quality. Locking levers seem very rugged. Have not tested the return to zero on this particular mount but all others I have tried had no issue. As always, good pricing from optics planet. Would buy again.

These are the best quick detachable mounts on the market. Perfect Zero every time. Super high quality… Great price. I use these on many guns. Have always had excellent results. Adjustments and fit are perfect. Military quality as expected.

THIS IS A PERFECT MOUNT FOR ANY TRIJICON ACOG SIGHT. FIT IS PERFECT AND LOCK UP SOLID AND IN PLACE. ONCE YOU GET THIS MOUNT SET, IT'S ON AND ISN'T GOING TO MOVE. EASY TO REMOVE AND WHEN PLACED BACK ON GUN HOLDS ZERO. LIGHT WEIGHT SOLID CONSTRUCTION. IF YOU HAVE A ACOG AND WANT THE BEST MOUNT FOR THE PRICE, THIS IS IT. OPTICS PLANET ONLY PLACE TO GET IT IN FDE !

I picked the FDE model, great color. Base is easy to adjust tension on rail, no tools needed. Mount is low profile, and everything that I was looking for
