B&T ROTEX-SF Muzzle Brake 5.56 NATO – Quick-Detach Suppressor Host

The B&T ROTEX-SF Muzzle Brake is a precision-machined QD mount designed to serve dual purposes: effective recoil reduction during unsuppressed fire and a secure attachment point for B&T ROTEX-series suppressors. Featuring aggressive side ports, this brake redirects propellant gases to mitigate muzzle rise and felt recoil in 5.56 NATO chamberings, while its indexed locking collar system enables rapid suppressor attachment without tools or timing adjustments.

Manufactured from heat-treated steel with a durable black oxide finish, the ROTEX-SF brake installs via standard 1/2x28 threads common to AR-15 pattern rifles and other 5.56 platforms. The integrated locking mechanism uses spring-loaded ball detents to ensure repeatable zero when mounting compatible suppressors. Note: This is a firearm component only—attaching a suppressor requires compliance with NFA regulations including ATF Form 4 approval and applicable state/local laws.
