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.

Echo Single Port Muzzle Brake for Breek-LOK 3QD
Purchased the Echo Single Port Muzzle Brake for Breek-LOK 3QD and the matching device that threads on the barrel. They're both impressively machined/manufactured, connect easily and solidly and provide insurance that they'll remain that way.
