The Dead Air KeyMo Muzzle Brake (brand part no. DA162) gives .45-caliber-class rifles a dedicated recoil-reducing brake built around Dead Air’s KeyMo mounting system, a quick-attach interface that lets a shooter swap between a brake and a KeyMo-compatible suppressor without losing zero. Threaded 5/8×32 to match common .45-caliber-class host barrels, it directs propellant gas outward and rearward to cut muzzle rise and felt recoil on follow-up shots. Because it shares Dead Air’s KeyMo interface, the same threaded base doubles as the mounting point for a KeyMo suppressor, so a shooter can run the brake alone today and add sound suppression later without changing the base on the barrel. It’s a straightforward upgrade for a .45-caliber-class build that wants brake performance now and suppressor-ready compatibility down the road.
