The Dead Air Silencers Odessa Piston, threaded 1/2×28 (brand part no. DD440), is a booster piston built for the Odessa suppressor platform on pistol hosts threaded to the widely used 1/2×28 pattern. It lets the barrel move independently of the suppressor’s added mass, which keeps a recoil-operated pistol cycling reliably with a can attached. As a wear item, it can be replaced on its own as internal springs and seals age without buying a whole new suppressor. It ships as a standalone service part, separate from the suppressor tube.

Key Specifications
