Product description
Roller-Delayed for Increased Reliability and Less Felt Recoil
The Maxim Defense Roller Delayed Blowback CQB Length Buffer is specifically engineered to optimize blowback-operated AR-9 platforms, particularly those with compact buffer systems like the Maxim CQB stock. Designed to mimic the function of a roller-delayed system, this buffer significantly reduces felt recoil, bolt bounce, and cyclic rate. Perfect for PCC competition guns, suppressed setups, or defensive carbines, this drop-in buffer uses an internal spring and roller mechanism to delay the rearward movement of the bolt. The result is less wear on components, reduced recoil impulse, and improved reliability, especially during rapid fire or with mixed loads.
Features
- Roller-delayed design reduces bolt speed and softens recoil impulse
- CQB-length configuration for use with short buffer tubes and compact stocks
- Enhances reliability and control in blowback 9mm AR platforms
- Drop-in compatibility with standard AR-15 carbine buffer tubes
- Works with most AR-9 bolts with no special carriers or uppers required
- Helps prevent bolt bounce and premature wear
- Ideal for competition, suppressed, or high-volume shooting
- Durable construction with Maxim-grade internal components
- Made in the USA by Maxim Defense
- NOTE: The RDB System is designed specifically for 9mm AR platforms and is not compatible with other calibers.
