Dead Air Armament Mojave Fixed Barrel Spacer 17-4 Stainless Steel Heat-Treated PB139

Dead Air Mojave Fixed Barrel Spacer is a dedicated spacer for Mojave silencers equipped with a booster assembly. Built from 17-4 stainless steel with a heat-treated stainless finish, it replaces the booster spring to mimic direct-thread operation and protect the booster assembly when used on fixed-barrel firearms. It installs around a Mojave piston inside the PB500 Booster Assembly, providing a quick and cost-effective conversion for pistol-caliber carbines and other fixed-barrel platforms.
