Dead Air Mojave Piston 9mm 1/2x28 Suppressor Accessory

The Dead Air Mojave Piston (MPN PB440) is the factory-direct replacement piston for the Dead Air Mojave 9 suppressor. Cut with 1/2x28 threads, this piston is purpose-built to mount the Mojave 9 on 9mm Luger barrels and is engineered specifically for use on tilting-barrel handguns and pistol-caliber carbines.

The piston interfaces directly with the Mojave 9's booster assembly (sold separately) to keep the host action cycling reliably while the can is mounted. Its geometry is matched to Dead Air's suppressor-mounting spec, giving Mojave 9 owners a factory part that drops in without modification. Finished in a low-glare black coating, the PB440 lets you swap the Mojave 9 between hosts with different thread pitches, or replace a worn piston on a frequently-used setup.
