Abstract
An assembly for a firearm (10) includes a sleeve (22) connected to the receiver or receiver end of the barrel (18). The sleeve (22) extends beyond the discharge end of the barrel (18) and includes inwardly extending projections (42) abutting or juxtaposed to a peripheral section (44) of the discharge end of the barrel (18). A noise suppressor (24, 50) threads onto the sleeve (22) . Some of the propellant gases are redirected and cooled by the noise suppressor (24, 50) in a conventional manner. Some of the propellant gases are redirected into an annulus (46) between the barrel (18) and sleeve (22) where they are cooled and some of their volume is reduced thereby increasing the efficiency of the noise suppressor (24, 50).
Claims21
A firearm comprising a receiver having a barrel terminating in a muzzle, the barrel being imperforate on its periphery from the receiver to the muzzle and an assembly comprising
- an imperforate rigid sleeve connected to the firearm at a location adjacent a junction of the barrel and receiver and distant from the muzzle, the sleeve surrounding the barrel and extending from the junction to adjacent the muzzle;
- and
- a noise suppressor rigid with the sleeve having a series of noise suppressing elements, an upstream element being spaced from the muzzle,
- there being an annular space between the rigid sleeve and the barrel open to receive propellant gases exiting out of the muzzle.
A noise suppressor for a firearm comprising
- a tubular housing having an imperforate side wall and providing an entrance end and an exit end and a connector adjacent the entrance end for attachment to a firearm;
- a multiplicity of noise suppressing elements, inside the housing, each of the noise suppressing elements comprising a baffle having a central opening for passing a projectile from the firearm, the elements being separately made and then fused together into a unit;
- and
- a closure seating against the housing and having a protrusion extending outwardly from an end of the tubular housing sufficiently far for a user to grasp, the closure being arranged to couple and uncouple from the housing upon manipulation of the protrusion;
- the noise suppressor comprising no more than three parts whereby it may be readily disassembled, for cleaning, by manipulating the protrusion.
