Accessory mounting hand guard for firearm

摘要

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.

1. A hand guard for a firearm that includes a barrel and a barrel nut extending longitudinally forward from a receiver of the firearm, the hand guard comprising:
an elongated tubular housing having a lumen extending between opposite ends of the housing; a mounting assembly coupled concentrically to a rear end portion of the housing, the mounting assembly including a pair of opposing transverse surfaces respectively disposed on opposite sides of a transverse flange located on a front end of the barrel nut, at least one of the transverse surfaces being longitudinally moveable 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; and an urging mechanism comprising:
an inclined plane disposed in front of a rearward facing one of the transverse surfaces, anda radially extending set screw disposed above the inclined plane and arranged to urge the rearward facing transverse surface longitudinally toward the other transverse surface when an end of the set screw is radially advanced against the inclined plane.
