Abstract (en)
[origin: WO2009139803A2] 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).
