The KeyMo 46 quick detach mount is our newest big-bore Keymo muzzle device that gives you efficient muzzle braking on calibers up to .458, while offering a faster, rock-solid attachment method.
For effective mounting on rifle barrels with little to no shoulder, the KeyMo 46 features a muzzle-seating design that does not require the use of shims.
The muzzle brake ports are designed to efficiently distribute gas and pressure inside your Dead Air silencer for superior performance and longer service life. When it comes to removal, the suppressor can be easily removed without carbon-locking onto the mount. All this while still delivering the durability you’ve come to expect from a Dead Air mount. The KeyMo 46 is compatible with all Dead Air KeyMo adapter-equipped silencers.

NOTE: Please consider the caliber limitations of the suppressor when mounting the KeyMo 46 on your rifle.
