Breek Arms Delivers Ultra-Compact Design with Plan B Compatibility
Features
- Ultra-compact single-port design for space-constrained builds
- 90° horizontal blast-vectoring ports reduce recoil and muzzle rise
- Plan B/Atlas mounting system for seamless suppressor compatibility
- 4140 hardened steel with nitride finish
- Includes peel washer for proper installation
The Plan B Echo solves the problem of needing effective recoil control in minimal space while maintaining suppressor compatibility. It works exceptionally well for short barrel rifles, compact builds, and tactical applications where every inch matters but suppressor mounting capability is required. The Plan B/Atlas compatibility sets it apart by providing industry-standard suppressor mounting in an ultra-compact 1.75″ package that keeps rifles flat and fast through rapid fire.
Note: Echo muzzle brakes using .308 ammunition are tested and rated for 10″ barrels and longer. Use of peel washers or shims for installation is highly recommended.
