KGM Suppressors A-TMB-S-4 Taper Muzzle Brake M18x1.5 Steel Black Nitride

The KGM Suppressors A-TMB-S-4 Taper Muzzle Brake is the mounting foundation of KGM's taper-mount suppressor system. Machined from steel and finished in black nitride, this muzzle brake threads directly onto a rifle barrel cut to M18x1.5 and doubles as the integrated mount interface for KGM R30T, R65T, and R338 series suppressors.

Rather than requiring a separate thread adapter, the A-TMB-S-4 features a precision-engineered taper that allows a compatible KGM suppressor to slide over the brake body and lock concentrically into place. This taper-mount geometry keeps the suppressor aligned with the bore for repeatable point-of-impact shift, and the unit functions as a conventional radial muzzle brake when fired unsuppressed, redirecting propellant gas to reduce felt recoil and muzzle rise.

Measuring 4.7" overall and weighing approximately 3.1 oz, the A-TMB-S-4 is purpose-built for the European rifle thread pattern. This is a New, factory-finished KGM Suppressors part. Suppressor sold separately.
