KGM Taper Muzzle Brake Features The KGM Taper Muzzle Brake is machined from heat treated chromoly steel a material chosen for its strength and resistance to the heat and pressure generated at the muzzle. An OXyN gas nitride finish is applied over the steel giving the brake a hard corrosion resistant surface that holds up under repeated firing and field exposure. Threaded to the 5/8x24 standard the brake installs on rifles already cut to that common thread pitch without requiring additional gunsmithing. Bored to accept projectiles up to .338 caliber it supports a wide range of common precision rifle cartridges so the same brake can serve builds chambered anywhere from mid-size magnums down to smaller bore precision rounds. Heat treating the chromoly steel before finishing helps the brake keep its dimensional stability under the repeated thermal cycling that comes with sustained precision rifle shooting. Beyond its muzzle brake function this device serves as the dedicated mounting interface for KGM s R30T and R338 suppressors allowing shooters to quickly attach and detach a suppressor from a rifle already fitted with this brake. This taper mount design is built specifically to deliver a secure repeatable connection between rifle and suppressor so point of impact stays consistent between suppressed and unsuppressed fire once the brake is zeroed on the host rifle. The OXyN gas nitride finish also provides a durable low maintenance exterior that resists the fouling and residue that accumulates during extended shooting sessions cutting down on the cleaning demands placed on the muzzle end of the barrel. Because the brake uses the industry standard 5/8x24 thread pitch it drops onto existing threaded barrels without needing a gunsmith to re-thread the muzzle. The KGM Taper Muzzle Brake gives precision rifle shooters a rugged suppressor ready muzzle device for sale at GrabAGun suited to anyone standardizing a rifle build around the KGM R30T or R338 suppressor platform.
