The Breek-LOK 3QD QD Suppressor Attachment system sets the standard for quick-detach mounts, delivering unmatched speed and ease of use. Its streamlined profile integrates seamlessly with firearms, enhancing both aesthetics and performance. 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. The Echo is designed to be pinned & welded on 14.5″ barrels to meet the 16″ Federal minimum length requirement and avoid SBR classification. Its sleek, compact design complements any buildideal for SBRs or pistol-caliber carbineswhile maintaining a clean, refined appearance.
