Breek Arms BRK4330 Echo Single-Port Muzzle Brake | .223/5.56

The Breek Arms BRK4330 Echo Single-Port Muzzle Brake is a compact, steel muzzle device finished in black nitride and designed for use with .223 Rem/5.56 NATO. It integrates with the Breek-LOK 3QD quick-detach suppressor attachment system for suppressor-ready builds. The Echo uses a pattern of horizontal ports and small jet holes to moderate muzzle rise and promote faster follow-up shots while reducing felt recoil.

Typical applications include competitive rifle matches where rapid follow-up hits matter, and short-barrel or SBR-oriented builds that pair with quick-detach suppressor systems. The device is intended for pinned-and-welded installation on 14.5-inch barrels when a 16-inch minimum overall barrel length is required under federal law.
