Patent number: 8474361Abstract: A method for reducing the weight of a silencer without compromising durability. By reducing the silencer housing wall thickness weight is removed from the silencer module. Areas on the housing where material is removed are primarily selected based on the internal pressure generated in a given chamber of the silencer. Further, removal of external material is selected based on the baffle arrangement. Individual chamber pressure is influenced by the muzzle pressure of the host firearm and the baffle style and baffle orientation within the silencer being used.Type: GrantFiled: May 5, 2008Date of Patent: July 2, 2013Assignee: Advanced Armament Corp., LLCInventor: Kevin Tyson Brittingham

Patent number: 8272306Abstract: The herein proposed device relieves an autoloading handguns' barrel from the weight of the silencer allowing it to cycle properly. This improved booster housing for a silencer affords the user ten positions of orientation. A more robust orientation mechanism which minimizes rotational movement of the associated piston when it is fully seated within the booster housing is provided for. Increased accuracy of the host firearm is achieved through the minimization of rotational play. My improved booster housing design is lighter in weight than other similar designs and utilizes a coaxial expansion chamber between the housing and the interior of the silencer tube to increase sound reduction.Type: GrantFiled: August 6, 2008Date of Patent: September 25, 2012Assignee: Advanced Armament Corp.Inventor: Mike Smith

Patent number: 8096222Abstract: The present invention relates to a silencer for reducing muzzle blast and noise of firearms or similar devices. The present silencer has a hollow cylindrical or other shape casing comprising front and rear end caps and an opening aligned along a longitudinal axis defining a passage for a projectile and propellant gases to emerge from the muzzle opening. A plurality of serially placed baffles of symmetrical or slanted orientation and intervening coaxial spacers are positioned within the casing and define a multitude of chambers among the baffles, spacers, and outer housing. The baffles shear propellant gases away from the projectile path and through openings or ports into additional chambers formed between the spacers and outer housing. The arrangement of baffles and spacers provides flow-impeding paths, dispersion, and controlled expansion of gases and lowers gas temperature to reduce audible noise and observable signature of the muzzle blast.Type: GrantFiled: January 5, 2011Date of Patent: January 17, 2012Assignee: Advanced Armament Corp., LLC.Inventor: Robert Silvers

Patent number: 7926404Abstract: A gas regulator which incorporates a flash hider for use with gas operated firearms. By incorporating a flash hider around the gas vent for the host firearms operating system, unburnt particles which produce flash from this exit point may be effectively disrupted. By disrupting and redirecting these unburnt powder particles flash is thereby eliminated from the firearms operating system. In the preferred embodiment, an open-pronged flash hider is used, but the device is not limited to this specific design. Military end users are particularly interested in an article of manufacture which eliminates flash from the gas system since it will disrupt the use of night vision and give away a soldier's position during low light or no light operations.Type: GrantFiled: December 1, 2007Date of Patent: April 19, 2011Assignee: Advanced Armament Corp.Inventor: Kevin Tyson Brittingham
