The Dead Air Xeno Radial Brake is an exceptionally engineered muzzle device built to serve as a stand-alone recoil reducer and a low-profile mounting footprint. It features an omnidirectional radial port system that efficiently disperses combustion gases to mitigate muzzle rise without requiring timed shims or precise index tuning. Machined from rugged stainless steel treated with an ultra-hard black nitride coat, it is heavily resistant to carbon buildup, copper fouling, and thread galling. The internal interface employs left-handed mating threads that work directly with Xeno R-Series and P-Series HUB adapters, completely preventing the adapter from accidentally backing off the barrel when removing the suppressor. Its compact length positions the tip shallowly inside the suppressor blast chamber, preventing premature baffle erosion while protecting core firearm accuracy.
