Breek Arms Echo Single-Port Plan B Features The Breek Arms Echo Single-Port Plan B is engineered around an ultra-compact single-port design built specifically for the Plan B mounting system keeping the overall footprint minimal while still delivering effective recoil control. Its 90-degree horizontal blast-vectoring ports redirect propellant gas outward significantly reducing both recoil and muzzle rise so the shooter can stay on target through faster follow up shots. 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 excessive wear or corrosion. At just 1.75 inches in overall length it adds minimal length to the muzzle while still providing meaningful recoil mitigation. Because it is built for the Plan B mounting standard the brake allows for fast seamless suppressor swaps without needing to re-zero a point of impact shift each time a major advantage for shooters who move between suppressed and unsuppressed configurations. Threaded 1/2x28 for 9mm applications it installs directly onto a properly threaded barrel and is torqued to spec with a 13/16 inch wrench for a secure fit. A peel washer is included to help index the brake s ports correctly during installation.
