Maxim Defense CQB Roller Delayed Blowback Buffer System, 9mm

The Maxim Defense CQB Roller Delayed Blowback Buffer System, 9mm (brand part no. MXM47838) converts a straight-blowback AR-9 into a roller-delayed system for noticeably more efficient, reliable cycling. The system works exclusively with Maxim Defense CQB-length buffer tubes, ensuring a seamless fit rather than a generic mil-spec approximation. A locking mechanism delays bolt opening until pressure in the chamber has already dropped, which reduces felt recoil, improves accuracy, and makes the platform easier to run with a sound suppressor attached, since it tempers the extra bolt velocity a suppressor can add. Maxim Defense designed the system to be easy to install while delivering unmatched performance for an upgraded AR-9. For AR-9 owners who want smoother cycling and less felt recoil, this buffer system is a genuine mechanical upgrade over straight blowback.
