Breek-LOK 3QD Compatible Muzzle Devices

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 your firearm, 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
build—ideal for SBRs or pistol-caliber carbines—while maintaining a clean, refined appearance.

*Ensure the barrel and muzzle device is 16″ or greater to meet the federal minimum length requirement to avoid SBR classification before pin & weld as some barrels shoulder length may differ.
