The Dead Air KeyMo 46 quick‑detach muzzle device is engineered to deliver strong recoil control for larger calibers while providing a fast, secure attachment interface for suppressors equipped with the KeyMo system. Precision-crafted for .45 caliber firearms with a .578″x28 thread pattern, the DA160 features a Black Nitride finish and weighs 3.5 oz with a length of 2.58″. Constructed from 4140HT Chromium-Molybdenum Steel, this brake is built for durability and reliability.
The muzzle‑seating design supports barrels with minimal shoulder contact and eliminates the need for shims during installation, making setup straightforward. The muzzle brake ports are designed to efficiently distribute gas and pressure inside your Dead Air silencer for superior performance and longer service life, and the suppressor can be easily removed without carbon-locking onto the mount. The KeyMo 46 is compatible with all Dead Air KeyMo adapter-equipped silencers.
