Abstract
In one example, an accessory mount for a gun, such as a machine gun, can include a base configured for attachment of the accessory mount to the gun, a holding mechanism for fixing the position of the base in relation to the gun, and an elongated accessory mounting arm coupled to the base and extending forwardly therefrom, the arm comprising a beam having a vertical web with at least one flange disposed at an upper and/or a lower end thereof.
Claims16
An accessory mount for a gun, the mount comprising:
- a base configured to attach the accessory mount to the gun, wherein the base comprises an annular structure having a circular central opening configured to be disposed concentrically over a barrel of the gun and a concentric counterbore extending into a rear surface thereof, wherein the counterbore defines a substantially planar floor and is configured to be disposed concentrically over a front end of a shroud of the gun, with the floor of the counterbore disposed against a substantially planar front surface of the shroud;
- a holding mechanism configured to fix the position of the base in relation to the gun, wherein the holding mechanism comprises:
- a plurality of threaded bolts extending rearwardly from the base through respective bolt apertures contained therein,
- a plurality of cleats, each having an opening through which a rear end portion of a respective one of the bolts extends and a hook adapted to grip an edge of a corresponding hole in the shroud of the gun, and
- wherein the cleats are arranged such that advancement of the bolts into respective ones of the cleats causes the hook of each cleat to grip the edge of the corresponding hole in the shroud of the gun and the planar floor of the counterbore in the rear surface of the base to be pulled into contact with and held against the planar front surface of the shroud;
- and
- an elongated accessory mounting arm coupled to the base and extending forwardly therefrom, the arm comprising a beam having a vertical web with at least one flange disposed at an upper and/or a lower end thereof.

An accessory mount for a gun, the mount comprising:
- a base configured to attach the accessory mount to the gun, wherein the gun includes a yoke defining a first mounting and alignment feature, wherein the base comprises a bracket having a second mounting and alignment feature that is complementary in shape to the first mounting and alignment feature;
- a holding mechanism configured to fix the position of the base in relation to the gun, wherein the holding mechanism comprises at least one threaded fastener extendable through an aperture in the bracket and into a corresponding threaded aperture in the yoke while the first and second mounting and alignment features are engaged with each other;
- an elongated accessory mounting arm coupled to the base and extending forwardly therefrom, the arm comprising a beam having a vertical web with at least one flange disposed at an upper and/or a lower end thereof;
- wherein the bracket includes a pair of forwardly extending slots in a side surface of the bracket facing away from the gun, the slots being configured to receive a side surface of a rear end portion of the accessory mounting arm in a complementary engagement;
- and
- at least one threaded fastener extending through at least one through aperture in the accessory mounting arm and into a corresponding threaded aperture in the bracket.

An accessory mount for a gun, the mount comprising:
- a base configured to attach the accessory mount to the gun, wherein the gun includes a gun mount having a front surface, a portion of which is substantially flat and which includes at least one threaded mounting aperture disposed therein, wherein the base comprises an L-shaped bracket having an upstanding leg with a substantially flat rear surface and at least one through-hole corresponding to the at least one threaded mounting aperture in the gun mount;
- a holding mechanism configured to fix the position of the base in relation to the gun, wherein the holding mechanism comprises at least one threaded fastener extendable through the at least one corresponding aperture in the bracket and into the at least one threaded mounting aperture in the gun mount;
- an elongated accessory mounting arm coupled to the base and extending forwardly therefrom, the arm comprising a beam having a vertical web with at least one flange disposed at an upper and/or a lower end thereof;
- wherein the bracket includes a leg extending forwardly from the upstanding leg, the forwardly extending leg having an upper surface with a pair of forwardly extending slots disposed therein, the slots being configured to receive a bottom surface of a rear end portion of the accessory mounting arm in a complementary engagement;
- and
- at least one threaded fastener extending through an aperture in the accessory mounting arm and into a corresponding threaded aperture in the bracket.
