  • Patent number: 9476672
    Abstract: Hand guards for firearms and related methods are provided. In one example, a hand guard for a firearm includes an elongated tubular housing having a lumen extending between opposite ends thereof. A hand guard mounting assembly is coupled concentrically to a rear end portion of the housing. The mounting assembly includes a pair of opposing transverse surfaces respectively disposed on opposite sides of a transverse flange located on a front end of a barrel nut extending forwardly from a receiver of the firearm. At least one of the transverse surfaces is longitudinally moveable toward the other transverse surface. A mechanism adjustably urges the at least one transverse surface longitudinally toward the other transverse surface so as to clamp the flange firmly between the two transverse surfaces and such that the barrel of the firearm is disposed concentrically within the lumen of the housing.

  • Patent number: 9127906
    Abstract: Hand guards for firearms and related methods are provided. In one example, a hand guard includes an elongated housing. The elongated housing comprises a lumen configured to substantially surround an intermediate portion of a barrel of a firearm, a lateral side wall, and a pair of inclined side walls respectively disposed on opposite sides of and inclined relative to the lateral side wall. Each of the inclined side walls comprises an elongated slot, wherein the elongated slots of the inclined side walls define a pair of angulated faces of a rail adapted to receive an accessory to be mounted thereon. For example, the rail may be a reduced-height Picatinny rail provided by the lateral side wall of the housing.

  • Patent number: 8595970
    Abstract: An embodiment of a hand guard for a firearm, such as a rifle, includes an elongated tubular housing comprising an upper part, a lower part, opposite open ends, and a lumen configured to receive an intermediate portion of a barrel of a firearm longitudinally therein. An expansion collar is disposed at one end of the housing. The expansion collar has an expansion mechanism configured to adjustably compress the expansion collar and the lower part of the housing longitudinally between a pair of surfaces respectively disposed at opposite ends of the intermediate portion of the barrel.
