Breek Arms LOK 3QD Echo Single-Port Muzzle Brake Features The Breek Arms LOK 3QD Echo Single-Port Muzzle Brake vents gas through 90 degree horizontal blast-vectoring ports pushing recoil energy out to the sides instead of straight back into the shooter s shoulder. That redirection significantly reduces felt recoil and flattens muzzle rise letting the shooter stay on target for faster more accurate follow-up shots. Six small jet-effect holes add an additional layer of control over muzzle movement and stability refining the brake s behavior beyond the main venting ports. Threaded 5/8x24 for .30 caliber barrels the Echo also seats directly onto the Breek-LOK 3QD quick-detach system so a suppressor can be swapped on and off without re-zeroing a separate mount. Built from 4140 hardened steel finished in black nitride the Echo holds up to repeated suppressor cycling and sustained firing without losing its finish or fit. At only 2.06 long and 1.7 oz it keeps a compact low-profile silhouette that suits SBR builds and pistol-caliber carbines where length and weight matter. A peel washer ships with the brake for correct clocking during installation torqued to a specified 20 to 30 ft lbs for a secure mount. Designed and manufactured in America the Echo is intended for use with pinned and welded 14.5 barrels that reach the federal 16 minimum giving builders a brake that controls recoil while keeping the overall package clean and purpose-built.
