Claim 18:
19. A suppressor assembly for a firearm having a receiver and a barrel connected to the receiver, the suppressor assembly comprising:
a first tube having a first end adapted to be coupled to the receiver and defining at least one port arranged proximate to the first end and extending in a radial direction, wherein the first tube is configured to be arranged around the barrel defining a radial gap therebetween, wherein the first tube is configured to extend outwardly of the barrel in a longitudinal direction defining an axial gap therebetween, wherein the radial gap and the axial gap together define an expansion volume around the barrel;
an end cap arranged at a second end of the first tube and coupled to the first tube, wherein the end cap defines an outlet opening adapted to be arranged coaxially to the barrel to facilitate an exit of a bullet from the first tube;
a second tube configured to be arranged around the first tube and defining an annular volume therebetween; and
at least one end plug disposed between the first tube and the second tube and engaged with the first tube and the second tube,
wherein at least one of
the second tube defines at least one outlet extending in the radial direction, or the at least one end plug defines a plurality of exit ports arrayed circularly around a central axis of the end plug and extending in the longitudinal direction,
wherein propellant gases generated during firing of the bullet exits a muzzle of the barrel, expand inside the expansion volume and enter the annular volume from the expansion volume through the at least one port.
