Breek Arms Echo Single-Port Plan B Features The Breek Arms Echo Single-Port Plan B uses 90 degree horizontal blast-vectoring ports to redirect propellant gas outward rather than upward which significantly reduces recoil and muzzle rise and keeps the sight picture flatter for faster follow-up shots. Machined from 4140 hardened steel and finished with a nitride coating the brake holds up to repeated firing cycles and resists corrosion in the field. The Plan B and Atlas mounting interface gives the shooter guaranteed alignment every time a suppressor is attached or removed eliminating the baseline shift that can come with other quick-detach systems. At an overall length of 1.75 inches and a weight of just 2.3 ounces the sleek low-profile design adds minimal length and mass to the end of the barrel. Threaded 1/2x28 for .223 Rem and 5.56 rifles the Echo Single-Port Plan B installs with a 13/16 inch wrench and torques to 20 to 30 foot pounds with an included peel washer to protect the finish during final timing. Because it shares the Plan B and Atlas mount standard shooters already running that ecosystem can swap between a bare brake and a suppressor without removing a separate mount from the barrel. The compact single-port chamber keeps the brake s footprint tight for use on short-barreled rifles and pistols where rail space and overall length matter. Designed and manufactured in the United States the Breek Arms Echo Single-Port Plan B Brake is a reliable recoil management upgrade for competition duty and range use.
