Product Description
The Dead Air Armament KeyMo Muzzle Brake is a high-performance muzzle device designed to reduce recoil while also serving as a fast, secure mounting interface for Sandman Series and other suppressors equipped with the KeyMo system. Built for big-bore use, it delivers a flatter-shooting rifle with less concussion than many traditional muzzle brakes, and its durable black nitride finish is made for hard use. When you’re ready to run suppressed, the KeyMo interface allows quick attachment and removal with compatible KeyMo-equipped suppressors.
Product Highlights
- KeyMo mounting interface for quick attachment of compatible KeyMo-equipped suppressors (including Sandman Series and KeyMo-equipped setups)
- Big-bore muzzle brake design helps manage recoil while maintaining effective gas redirection
- 5/8x24 thread pitch for common .45/.46-caliber rifle applications
- Black nitride finish for corrosion resistance and long-term durability
