Product Description

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

Note: The RDB System is designed specifically for 9mm AR platforms and is not compatible with other calibers. This system is not rated for full-auto use.
