Dead Air KeyMo Muzzle Brake | 3/4-24 | DA103

The Dead Air KeyMo Muzzle Brake (DA103) is a KeyMo-compatible muzzle device designed to provide a mounting interface for KeyMo-equipped suppressors while delivering a flatter shooting experience through reduced recoil and muzzle rise. Constructed from durable 4140 HT alloy steel with a black nitride finish noted in product materials, it uses a sealed taper to minimize carbon locking and simplify suppressor removal. This brake is intended for use where a KeyMo mounting solution and controlled recoil are priorities.

Typical applications include suppressed precision or long-range shooting and competition/target work where rapid attach/detach and consistent muzzle control are important.
