Description
The RRD Recoil Reduction Device is a lightweight, multi-functional muzzle device engineered for unmatched firearm control. Its primary function is to drastically reduce recoil and muzzle rise by diverting gases 90° to the side and upward.
During development, we utilized high-speed cameras to analyze gas dispersion and refined multiple prototypes before finalizing the graduated baffle structure. This innovative design ensures even gas dispersion and a controlled release, delivering superior recoil management while also minimizing flash—making the RRD one of the few muzzle brakes that also functions as a flash hider.
Beyond recoil control, the RRD enhances accuracy and follow-up shot speed. Its optimized cut-out design effectively vents gases without interfering with sights or optics, keeping you locked on target.
Despite its impressive performance, the RRD remains compact and lightweight, adding minimal length while maximizing control—making it an essential upgrade for your firearm.
Key Features:
- Drastically Reduce Recoil
- Eliminate Muzzle Rise
- Enhances stability and shot consistency
- Reduce flash signature on barrels 12” and longer
- Lightweight & Durable Build

PROFESSIONAL INSTALLATION RECOMMENDED
- Shouldermount muzzle devices index against the shoulder of the barrel and will require a Shouldermount shim kit for timing
- Facemount muzzle devices index against the face of the muzzle and will require a Facemount shim kit for timing
- For Facemount devices, we recommend the use of an alignment rod for installation by a certified professional to ensure the Facemount shims are stacked properly and do not make contact with the projectile exiting the muzzle
- Multiple shims can be used to achieve proper timing
- We recommend 30-40ft/lbs of torque along with Rocksett applied to the threads
- Improper installation may result in damage to the device and/or the suppressor as well as potential injury to the user
