The Dead Air Mojave Piston is a replacement piston threaded to the M16x1 pattern, built for .45 caliber hosts, from Dead Air Silencers (brand part no. PB445). It lets owners swap an existing Dead Air Mojave silencer onto a host firearm with a different barrel thread by changing out the piston at the rear of the suppressor. It’s a genuine Dead Air service part, not a standalone suppressor, so it ships and transfers like any other Title I accessory. Note that manufacturer listings for this part are inconsistent on whether the M16x1 thread is left-hand or right-hand, so confirm the correct handing against your Mojave and host barrel before ordering.
