Product Description

Maxim Defense’s Roller Delayed Buffer (RDB) System is designed exclusively for 9mm AR-pattern platforms, transforming your firearm into a roller-delayed blowback system. This innovative design reduces felt recoil, improves reliability, and delivers smoother operation by allowing gas pressure to stabilize before extraction. It also minimizes friction commonly found in standard buffer systems for enhanced overall performance.

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.
