ROLLER DELAYED BUFFER (RDB) SYSTEM – FOR 9mm AR PLATFORMS ONLY
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.
KEY FEATURES:
- Reduces felt recoil
- increases reliability
- Minimizes friction for enhanced performance
IMPORTANT INSTALLATION NOTE FOR RDB SYSTEM
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.
At Maxim Defense, we take pride in designing and manufacturing high-performance firearms, suppressors and accessories that deliver exceptional reliability and durability. Your feedback and positive reviews are important to us, as they help us continually improve our products. If you experience any issues with your Maxim Defense products, please contact us at info@maximdefense.com, and we’ll work with you to resolve the matter as quickly as possible.

This thing is fantastic!

these work great for USPSA and/or Speed steel! You’re sight never leaves the target!!!

A fantastic option for those looking for a silent capture system that’ll not only help reduce recoil, but help keep your bolt where it needs to be to prevent bolt bounce or out of battery detonations. I personally am rocking the shorter version with the latest generation of the cqb stock. This thing can run through any speed or volume of fire you can throw at it and still make a huge difference in keeping your muzzle and sights right on target. The main thing to keep in mind for maintenance is to make sure to not pull back manually to expose the ball bearings unless you are prepared to find any that may fall out and fight spring pressure and gravity while trying to put any loose bearings back in.
