Maxim Defense Roller Delayed Buffer - 9mm AR-15 - Carbine

The Maxim Defense Roller Delayed Buffer System is a unique and innovative way to tame the violent recoil of 9mm blowback AR platform rifles. It features a captured spring design with a buffer that utilizes a roller delayed mechanism that ensures the bolt stays closed until pressures have stabilized allowing before extraction. This ensures extremely smooth operation resulting in reduced felt recoil and improving reliability. Whether you use your PCC for competition or target shooting, the Maxim Defense RDB system is a must have for a better shooting experience.

Note: Not compatible with other calibers.

Features:

• Fits 9mm AR platforms with carbine length receiver extension
• Reduces felt recoil and improves reliability
• Captured spring design minimizes friction for a smoother action
• Easy to install

To install the Roller Delayed Blowback (RDB) System, your 9mm bolt assembly must have an open channel to allow the guide rod to function properly during firing. For most 9mm bolts, meaning you will need to remove the pinned-in central mass. The central mass must be removable, but the bolt carrier group (BCG) should retain its full length without it, to ensure proper function with the RDB system.
