The Dead Air KeyMo 46 Muzzle Brake DA161 delivers a purpose-built mounting solution for KeyMo-equipped suppressor hosts on large-bore rifles. It features a .458 caliber bore, a 5/8x24 thread pitch, and is constructed from heat-treated steel with a black nitride finish for corrosion resistance. Its muzzle-seating, omnidirectional design allows direct installation without the need for shims and helps prevent carbon locking for easier suppressor removal.
This muzzle brake is engineered to provide secure, hassle-free suppressor attachment with reliable performance for demanding use on larger caliber platforms. Its construction and design support straightforward installation and long service life.
