Maxim Defense CQB Roller Delayed Buffer System - For 9mm AR Platform Only

Maxim Defense CQB Roller Delayed Buffer System - For 9mm AR Platform Only

Transform your 9mm AR-pattern pistol or carbine into a ultra-smooth roller-delayed blowback system with the Maxim Defense Roller Delayed Buffer (RDB) System. Purpose-built specifically for 9mm PCC builds outfitted with Maxim Defense CQB Stocks and Braces, this drop-in buffer conversion significantly reduces felt recoil, speeds up target re-acquisition, and enhances overall cycling reliability.

Operating by momentarily delaying the bolt opening until chamber pressures stabilize, the RDB system virtually eliminates bolt bounce and the harsh mechanical friction standard direct-blowback systems experience. The result is smoother extraction, reduced internal wear, and a softer shooting experience. Crafted with precision-machined stainless components in a silver finish, this non-full-auto-rated buffer system upgrade represents the ultimate performance enhancement for your 9mm PCC.

Features

Roller-Delayed Blowback Conversion:
Converts standard 9mm direct-blowback AR-15 platforms into a roller-delayed operating system for smoother bolt cycling and decreased internal wear.

Superior Recoil Mitigation:
Delays bolt unlocking until chamber pressures drop, drastically reducing felt recoil, muzzle rise, and physical fatigue during rapid-fire strings.

Maxim Defense CQB Compatibility:
Specially engineered and dimensioned for direct drop-in fitment with Maxim Defense CQB Series stocks and receiver extensions/braces.

Friction-Free Operation:
Eliminates the heavy spring grit and physical friction common in traditional PCC heavy buffers, boosting overall feeding and extraction reliability.

Precision Stainless Steel Build:
Machined from durable stainless steel components in a silver finish for long-lasting corrosion resistance and hard-use durability.
