Adapter assembly for firearm silencer

A silencer, comprising:

• an elongated silencer body having a distal end, a proximal end, and a projectile passage defined therethrough;
• a baffle core at least partially received within and extending along the projectile passage defined through the silencer body, the baffle core comprising a core body including a series of spaced baffles, with a passage extending through each of the baffles and substantially aligned with the projectile passage of the silencer body to allow a projectile fired from a firearm to pass therethrough;
• a piston positioned within the silencer body and comprising a piston body having a proximal end, a distal end, and a piston bore defined therethrough, the piston bore being substantially aligned with the passage of the baffle core;
• and
• an adapter assembly including a passage configured to at least partially receive the piston body therein to arrest movement of the piston body along the silencer body, and at least one biasing member engaged against the piston body to generate a force along the baffle core and/or the piston within the silencer body sufficient to prevent inadvertent dislocation or movement of one or more components of the silencer.
