Patent ID: 8015908

Claim:
A firearm suppressor, comprising: a one-piece, hollow outer can defining an interior with a cross-sectional shape and having: a longitudinal can length; an interior-threaded proximal end; and a radially closed distal end with a longitudinal can bore opening the interior of the can to the environment, the longitudinal can bore having a diameter sufficient to permit a projectile to pass therethrough; a monolithic extruded baffle having: a longitudinal extent; a proximal end portion defining a proximal longitudinal bore shaped to receive at least a portion of a firearm barrel and removably secure thereto; a distal end portion defining a distal longitudinal bore with a diameter sufficient to permit a projectile to pass therethrough; and intermediate baffle walls disposed between the proximal end and the distal end and defining at least one proximal baffle wall and at least one distal baffle wall, each baffle wall having a longitudinal bore axially aligned with the proximal longitudinal bore and the distal longitudinal bore, the at least one distal baffle wall extending radially outward to a shape substantially equal to the cross-sectional shape of the outer can to substantially prevent fluid from passing through the at least one distal baffle wall other than through the longitudinal bore, the at least one proximal baffle wall extending radially outward to a shape substantially less than the cross-sectional shape of the outer can to substantially permit fluid to pass through the at least one proximal baffle wall in addition to through the proximal longitudinal bore; a barrel nut having an interior barrel bore shaped to receive at least a portion of a firearm barrel therethrough and an outer-threaded distal end corresponding to the interior-threaded proximal end of the outer can to removably secure the outer can thereto the barrel nut being operable to secure a firearm barrel to a firearm; and the longitudinal can length being greater than the longitudinal extent of the extruded baffle such that, when installed on the firearm, the outer can seals the extruded baffle therein and extends from approximately the distal end of the baffle proximally to the barrel nut.
