A firearm, top cover, and feed lever. The feed lever includes a feed lever body having a feed lever track, wherein the feed lever body is configured to be pivotally mounted within a topcover assembly, and wherein the feed lever body is configured to pivot in response to a force transmitted by a roller of an operating group to the feed lever track during cycling of the firearm. The feed lever further includes a feed lever track first end, wherein the feed lever track first end comprises a feed lever track exit portion configured to receive the roller of the operating group after the roller exits the feed lever track via the feed lever track exit portion as the firearm cycles.

A link feed assembly. There is: a bolt carrier near a chamber of a modular weapon system; an infeed ramp, coupled to a first side of a weapon frame near the chamber; an outfeed ramp, coupled to a second side of the capon frame near the chamber and opposite the infeed ramp, positioned to form a space between the infeed ramp and the outfeed ramp; and a feed arm assembly coupled to the weapon frame and extending over the space between the infeed ramp and the outfeed ramp, the feed arm assembly functionally coupled to the bolt carrier such that cycling of the bolt carrier forward and backwards causes cycling of the feed arm assembly in a circuitous motion, the feed arm including a grabbing protrusion that is shaped to grab a top portion of a link during cycling of the feed arm assembly.
