The invention relates to a machine gun (1) comprising a feedway having a main surface (3) for sliding an ammunition belt (5), side faces (8, 23) that guide the ammunition (18) belt (5) during use, and at least one surface (25, 29) for retaining the belt (5), arranged on the upper edge of the side faces (8, 23), said retaining surfaces (25, 29) facing the sliding surface (3) and said retaining surfaces (29, 25) being open so as to allow the insertion of the ammunition (18) belt (5).

A feed tray assembly for a belt-fed weapon includes a bottom tray portion configured for mounting at a top of the weapon. The feed tray assembly further includes a feed tray cover mounted to the bottom tray portion and configured for lateral sliding opening and closing movement, such as on laterally extending pins riding in corresponding channels of the bottom tray portion. The feed tray cover has (1) a closed position in which it covers the bottom tray portion to retain the belt of ammunition during operation, and (2) an open position laterally displaced from the closed position to enable insertion of the belt of ammunition. Due to this lateral sliding movement of the feed tray cover, a sighting optic may be mounted on the weapon with a forward portion directly above the feed tray assembly without any undesired mechanical interference.

A belt-fed weapon includes an upper part defining a feed tray cavity, and a feed tray in the feed tray cavity, wherein the feed tray and feed-tray cavity are co-configured for lateral sliding insertion and removal of the feed tray to and from an installed position in the feed tray cavity. The arrangement enables insertion and removal of the feed tray without interference with an installed scope or similar optic, enabling maintenance or field stripping without requiring removal or re-sighting of the scope.

A recoil assembly for a rifle includes a barrel assembly, a bolt, bolt actuator, and a buffer assembly. The barrel assembly includes a barrel secured to a barrel extension. The barrel assembly is configured to be movably received through the fore end of the upper receiver and to move axially relative to the upper receiver when the rifle is fired. The barrel extension is coupled to a hydraulic buffer assembly located below the barrel extension and counteracts recoil forces acting on the barrel extension when the rifle is fired. An op-rod spring is coupled to an op rod extending from a gas piston assembly on the barrel. The op-rod spring counteracts recoil forces acting the bolt actuator when the rifle is fired.

A belt-fed firearm includes a top cover that can move in at least two degrees of freedom of motion (surge, sway, heave, roll, pitch, and yaw) that in combination allow movement of the top cover to both clear a peripheral accessory mounted to the firearm (such as optics) and open access to a feed surface to permit loading of cartridges to the feed surface.
