Kaw Valley Precision Muzzle Brake Features The Kaw Valley Precision muzzle brake is machined from 17-4 stainless steel a material chosen for its strength and resistance to the heat and pressure generated at the muzzle. A black nitride QPQ finish covers the brake providing corrosion resistance and an easy to clean surface after repeated firing sessions. At 2.05 inches overall length the brake adds a compact amount of length to the barrel while directing propellant gases to reduce felt recoil and muzzle rise. Its 0.500 inch bore allows it to work with any caliber up to that diameter giving it broad compatibility across calibers. Threaded 5/8x24 this brake is sized for common barrel thread patterns found on many rifle platforms. Built to work with ASR mount systems it allows shooters to quickly attach and detach muzzle devices such as suppressors without losing zero. That quick disconnect compatibility makes it a practical choice for shooters who swap between a bare brake and a suppressor depending on the application. This muzzle brake gives ASR system users a durable corrosion resistant option for recoil management.
