Breek Arms Echo Single-Port Plan B Features The Breek Arms Echo Single-Port Plan B brake uses a 90 degree horizontal blast-vectoring port design to significantly reduce recoil and muzzle rise keeping the rifle flatter and faster to get back on target between shots. Its ultra-compact single-port profile is built specifically around the Plan B mounting system allowing it to serve as both a standalone muzzle brake and a suppressor mount in one unit. Machined from 4140 hardened steel and finished with a nitride coating the brake is built to withstand the heat and pressure of repeated firing without degrading. At just 2 ounces for the .30 caliber version it adds minimal weight to the front end of a rifle build. Threaded 5/8x24 the Echo Single-Port is sized for .30 caliber rifles and is compatible with Plan B and Rearden suppressor mounting systems giving shooters a seamless way to swap a suppressor on and off without removing the brake itself. A peel washer is included to ensure proper alignment and timing when installing the brake onto the barrel. Measuring 1.75 inches overall the compact design keeps the barrel s overall length manageable even with the brake installed. Designed and manufactured in America this brake is built for shooters who want proven recoil reduction combined with quick-detach suppressor compatibility.
