  • Patent number: 8490315
    Abstract: The weapon sights can be used simultaneously in conjunction with another optical sight and can be mounted on the same weapon accessory rail as the other optical sight. The weapon sights include a front sight and a rear sight that detachably mount to the weapon's accessory rail, but are cantilevered and off-set so that they do not interfere with the optical sight mounted to the same accessory rail. The cantilevered configuration and off-set orientation of the rear sight assembly and the front sight post also allow the shooter to transition quickly between the weapon sight of this invention and an optical sight by simply canting the weapon 45 degrees to bring the desired sight on target and into the vertical of the weapon.

  • Publication number: 20130180797
    Abstract: In one example, a firearm sound suppressor includes a housing and an interior member. The interior member is disposed within the housing so as to define a chamber between an exterior surface of the interior member and an interior surface of the housing. The interior member includes a lumen and a plurality of vents extending through the interior member between the lumen and the chamber. The vents are adapted to pass combustion gases from the lumen to the chamber. The firearm sound suppressor also includes a blast deflector disposed between the vents and the interior surface of the housing. The blast deflector is adapted to prevent the combustion gases from impinging directly on the interior surface of the housing. Other embodiments are also contemplated.

  • Publication number: 20130180150
    Abstract: In one example, a firearm attachment includes a base adapted to be coupled to a firearm. The firearm attachment also includes a plurality of substantially longitudinal tines extending forwardly from the base and arranged circumferentially around a central axis of the attachment. The firearm attachment also includes at least one bore substantially concentric with the central axis. The firearm attachment also includes three longitudinal slots defined by sidewalls of adjacent ones of the tines and adapted to pass combustion gases from the bore. The sidewalls extend from the bore to an outer circumfery of the attachment. Sidewalls of adjacent tines lie in respective planes that intersect at an angle in a range of approximately 9 degrees to approximately 12 degrees. Other implementations and related methods are also provided.

  • Publication number: 20130180796
    Abstract: In one example, a firearm sound suppressor includes a housing, a baffle, and an inner sleeve adapted to be disposed within the housing and to substantially surround the baffle. The inner sleeve includes a sidewall adapted to slide against the housing to permit the inner sleeve with the baffle to be selectively inserted into and removed from the housing without the baffle contacting the housing, and a longitudinal split extending through the sidewall and between front and rear ends of the inner sleeve to permit the sidewall to flex to permit removal of the baffle from the inner sleeve. Other embodiments are also contemplated.

  • Patent number: 8459406
    Abstract: In one example, a method of aligning a firearm sound suppressor includes inserting a front portion of a body of an adapter into a socket of the firearm sound suppressor. The method also includes sliding a tab of the adapter into a slot disposed in an interior surface of the socket to rotationally align the firearm sound suppressor relative to a firearm. The method also includes contacting a plug of the adapter against the interior surface in a complimentary engagement. The plug is provided by a frusto-conical external surface of a rear portion of the body. The tab extends from the plug. Other embodiments are also contemplated.

  • Patent number: 8459405
    Abstract: In one example, a firearm sound suppressor includes a housing and an end plate disposed at a front end of the housing and comprising a bore extending therethrough. The bore includes a tapered portion that opens toward a front surface of the end plate. The tapered portion has an included angle in a range of approximately 10 degrees to approximately 25 degrees. The bore is adapted to pass a first round and first associated gases to reduce a size of a first muzzle flash caused by a firing of the first round by a firearm when the firearm sound suppressor is substantially at thermal equilibrium with a surrounding environment. Other embodiments are also contemplated.

  • Patent number: 8453789
    Abstract: In one example, a firearm sound suppressor includes a housing including a front end and a rear end. The rear end includes a flange that partially encloses the rear end and defines a rear aperture. The firearm sound suppressor also includes a back end member disposed substantially within the rear end of the housing and including a rear surface disposed in abutment with an inner surface of the flange to prevent the back end member from passing through the rear aperture. Other embodiments are also contemplated.
