RCB-SC Details

The RCB (Reduced Concussion Break) family of muzzle devices offers the BEST muzzle brake durability and performance for your rifle.

Optimized Rifle Performance
Elevate your rifle’s performance, with or without a suppressor, using our deliberately engineered muzzle devices. Designed with precision, both internally and externally, to perfectly complement your chosen suppressor, ensuring seamless integration and enhanced functionality.

Suppression and Accuracy Focused Design
The critical distance from the muzzle to the first baffle is expertly calibrated to optimize suppression, pressure management, and minimize flash signature. Our design ensures gas
is efficiently directed to enhance accuracy, with a concentric configuration that reduces flow disruption around the projectile.

Directional Port Timing for Superior Control
With strategically placed ports, our muzzle devices offer adjustable timing to maintain neutrality and maximize control. The Neutral position for shooters is positioning the non-ported flats at 12 and 6 o’clock for right-handed shooters, positioning the non-ported ends at 1 and 7 o’clock optimizes muzzle rise performance, while left-handed shooters can achieve the same by adjusting to 11 and 5 o’clock, enhancing offhand shooting precision.
