Maxim Defense’s Roller Delayed Buffer (RDB) System converts your 9mm AR-pattern firearm into a roller-delayed blowback system, reducing felt recoil and improving reliability. By allowing gas pressure to stabilize before extraction, it ensures smoother operation while virtually eliminating the friction common in standard buffer systems.
