Adapter assembly for firearm silencer

1. 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.

2. The silencer of claim 1 , wherein the adapter assembly comprises a spacer having a spacer body with a proximal end, a distal end, and a cavity defined therethrough that is configured to receive at least a portion of the piston body.

3. The silencer of claim 2 , wherein the spacer body comprises one or more vents defined therein to facilitate release of gases generated from firing of the firearm.

4. The silencer of claim 2 , wherein the spacer body is at least partially formed from aluminum, steel, titanium, carbon composites, or combinations thereof.

5. The silencer of claim 2 , further comprising a plurality of O-rings positioned along an interior surface of the spacer body, and at least partially engaging the piston body to provide a substantially gas-tight seal and/or a substantially cushioned fit between the spacer body and the piston body.

6. The silencer of claim 1 , wherein the silencer body further comprises a first portion along which the piston is located, and a second portion mounted to the first portion and along which the baffle core extends.

7. The silencer of claim 1 , wherein the at least one biasing member comprises at least one wave spring having a plurality of flattened segments each with a non-uniform, irregular body.

8. The silencer of claim 1 , wherein the at least one biasing member comprises one or more wave springs, Bellville washers, locking washers, curved disks, wake finger disks, elastomers, or combinations thereof.

9. The silencer according to claim 1 , wherein the piston comprises a series of threads disposed therealong substantially adjacent its distal end that are configured to cooperatively engage with one or more threads of the firearm.

10. The silencer according to claim 1 , wherein the baffle core comprises a substantially unitary structure or multiple interconnecting sections.
