Rugged Suppressors MB027 | 3-Port Brake | .338 | M18x1.5

The Rugged Suppressors MB027 is a purpose-built 3-port muzzle brake sized for .338 (8.6mm) bore diameters and fitted with an M18x1.5 thread pattern. It uses Rugged’s Dual Taper Locking System and is designed to manage recoil and muzzle rise on large-caliber rifles when shooting unsuppressed. Compatibility includes Rugged’s Alaskan360 and Alaskan360Ti suppressors, and it can be paired with a 1.375×24 threaded suppressor when used with the Rugged Universal Mount (R.U.M.).

Typical applications include long-range precision shooting and big-game field use where controllability and return-to-target speed matter without suppressor use. The design also supports integration into modular suppressed setups via the R.U.M. interface.
