Battle Arms Development Enhanced AR-15 Bolt Catch 9mm Black

The Battle Arms Development Enhanced Bolt Catch is an aftermarket replacement bolt catch for AR-15 pistol caliber carbine (PCC) builds chambered in 9mm Luger. It is designed to hold the bolt open after the last round is fired and to give the shooter a larger, easier-to-reach control surface for releasing the bolt.

The part is precision CNC machined from billet 8620 heat-treated steel rather than cast or metal injection molded material. It has oversize control surfaces, a raised T-shaped heel for positive bolt lock-back, and horizontal and diagonal serrations for grip. The finish is black, and the design is skeletonized to reduce weight.

It fits AR-15 PCC 9mm platforms. It is not compatible with dedicated Colt SMG-style lower receivers such as the STAG 9 and CMMG MK9, where last-round hold-open will not function. It is listed as compatible with the Norgon Ambi-Catch without interference.
