Breek LOK 3QD Echo Single Port Muzzle Brake - 1/2 x 28 - The Breek-LOK 3QD Suppressor Attachment System delivers fast, easy quick-detach functionality in a streamlined design that seamlessly complements your firearm's aesthetics and performance. Paired with the Breek-LOK 3QD Echo Single-Port Muzzle Brake, it features 90deg horizontal blast-vectoring ports to help reduce recoil and muzzle rise, while six precision-drilled ports create a jet effect for enhanced stability and control during rapid follow-up shots. Its design also helps minimize blowback for improved shooter comfort. Engineered for versatility, the Echo can be pinned and welded to 14.5in barrels to achieve the required 16in minimum barrel length under applicable federal law, helping avoid classification as a short-barreled rifle (SBR). With its compact profile and refined appearance, the Breek-LOK 3QD Echo is an excellent addition to a variety of firearm builds, including SBRs and pistol-caliber carbines.
