Abstract: Improvements to the M60 7.62-mm machine gun (1) to enable it to be cocked after the cover assembly has been closed without opening the latter (2) to minimize the possibility of a runaway gun (3) to enable a hot barrel to be changed without the necessity of using protective hand coverings (4) to eliminate the necessity of providing a bipod support assembly for every spare barrel (5) to provide for better control of the gun when firing from a standing position and (6) to simplify the construction of the gas cylinder and piston.

Abstract: A bipod mechanism for a light weight machine gun comprising a pair of individually telescopically adjustable leg assemblies and a mounting structure connectable in supporting relation with the gun mounting the pair of leg assemblies for movement between a folded transport position wherein the leg assemblies extend generally parallel alongside the longitudinal extent of the gun and a gun supporting and firing position wherein the leg assemblies extend downwardly in outwardly converging relation with respect to the longitudinal extent of the gun. Each of the leg assemblies includes an inner leg member of generally L-shaped cross-sectional configuration and an outer leg member of generally L-shaped cross-sectional configuration mounted in generally nested relation therewith. Pins sliding in slots provide for relative longitudinally sliding movement between the inner and outer members while in nested relation.
