A barrel adapter screws onto your rifle's threaded muzzle and stays there. It gives the muzzle a mounting interface, so the suppressor attaches to the adapter instead of the bare barrel threads. One adapter per rifle lets you move one suppressor between them. Many are quick-detach designs, and some also work as a muzzle brake or flash hider.
This one fits barrels threaded 1/2x28 and presents the SilencerCo ASR interface. A suppressor with a matching SilencerCo ASR mount attaches to it.

Which ones fit your barrel and host?
See all 612 in the Builder- The RCB (Reduced Concussion Break) family of muzzle devices offers the BEST muzzle brake durability and performance for your rifle.
- 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.
- 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.
- 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.
- Seeing as our standard muzzle devices also host our CK-Scrambler (QD) suppressor, we use Rocksett during the production process. This ensures that the muzzle device will not back out during mounting/ dis-mounting.
