The Dead Air Mojave Piston in .578×28 with a .45 caliber bore (brand part no. PB444) is the threaded piece that lets a Mojave suppressor cycle a tilting-barrel handgun. Dead Air designed it to work inside the PB500 Booster Assembly, which ships with the Mojave 9 and Mojave 45, along with the internal booster spring. The thread pitch and bore are part of the part number, so this version is the one for a .45 pistol threaded .578×28. It is a fitment part, and getting the pitch right is the whole job.
