Maxim Defense AR-9 9mm Luger Carbine Roller Delayed Buffer System

The Maxim Defense Roller Delayed Blowback System Buffer is a carbine-length drop-in buffer system for AR-9 builds chambered in 9mm Luger. It replaces the existing buffer and spring in compatible buffer tubes and fits most mil-spec AR-15 and AR-9 buffer tubes.

Built from steel, this system uses a roller-delayed locking mechanism that delays bolt opening until chamber pressure has dropped. It converts a straight-blowback AR-9 to roller-delayed operation and is intended to address AR-9 buffer-weight concerns, provide smoother cycling, and make suppressed operation easier.

The system measures 8.5" long, 2.1" wide, and 1.8" high. New Condition.
