Features
- Ultra-compact single-port design for space-constrained builds

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.
