The Breek-LOK 3QD Echo Single-Port Muzzle Brake significantly reduces recoil and muzzle rise through 90 horizontal blast-vectoring ports enabling rapid accurate follow-up shots. Six small holes create a jet effect further controlling muzzle rise and movement for added stability. Less blowback improves shooter comfort critical for competitive or defensive scenarios. Engineered for compliance the Echo is designed to be pinned & welded on 14.5in barrels to meet the 16in Federal minimum length requirement and avoid SBR classification.
