This mount worked perfect with the Primary Arms 2.5x prism scope. As always, the ADM mounts are great quality with a great price. I own 5 different ADM mounts and all top notch. The finish on these are outstanding and very easy to adjust for initial setup. I've never had an issue with return to zero on any of my ADM mounts.

Good solid mount. Comes with replacement screws. Fits Primary Arms AQ sight and probably others depending on hole spacing. Must replace foot on Primary Arms AQ sight, there is no upper Picatinny slotting. Note one set of screws hex slots are metric, the other SAE.

Necessary part for the 5x primary arms acss scope, exact fit for the factory base, be sure to warm the factory screws a little with a heat gun when taking them off. High quality part have them on all my EQ thanks opticsplanet great price

Changing the original Primary Arms 3x Prism Scope mount was a must. Needed the replacement mount to be QD and have a solid hold on top of my AR build. The AD-B3 Base met my requirements. It is a good solid mount. Comes with replacement screws. Fits Primary Arms 3x Prism Scope (it is also compatible with the Primary Arms 5x Prism Scope).

I recently got a 4x ACOG, but I could not stand the factory Trijicon mount. This mount has a single recoil lug, allowing for the mount to sit farther back on the rail of you're not running backup iron sights. The lockup is very firm. I tested return to zero at 50 yards, removing the ACOG and then reattaching, and this mount has a fantastic zero retention. I would highly recommend this if you're looking for an aftermarket ACOG mount or if there are other compatible optics that work with this.
