Patent ID: 8272306

Claim:
A booster for a silencer, comprising: a piston with a proximal end and a distal end, the proximal end of the piston configured to couple to a firearm such that a projectile can pass thorough the piston from the proximal end to the distal end, the distal end of the piston comprising a flange with a plurality of spokes; and a housing configured to couple to a silencer, the housing comprising an internal shoulder with a plurality of notches to receive a plurality of spokes of the piston flange; wherein the piston is translatable relative to the housing in at least one of the proximal and distal directions during discharge of a firearm coupled to the piston, and wherein a peripheral surface of the piston flange contacts an inner surface of the housing and slides along the inner surface during translation of the piston relative to the housing, wherein the housing is positioned within a firearm silencer and further comprises a plurality of holes such that expanding gases produced from a discharged firearm coupled to the booster can escape the housing in a direction substantially transverse to the path of a discharge projectile.
