Abstract: An adjustable firearm mount apparatus includes a main support. The main support includes a base end and an adjustment end opposite the base end. A longitudinal axis extends along a length from the base end to the adjustment end. At least one first mounting section is configured to interface with a first portion of a firearm. At least one passageway is defined in the main support and extends in a direction parallel to the longitudinal axis. An auxiliary support is slidably connected to the main support nearer the adjustment end than the base end. The auxiliary support includes at least one elongate member received in the passageway and at least one second mounting section configured to interface with a second portion of the firearm.

Abstract: An M240 machine gun barrel assembly with a barrel with a muzzle end at the distal end of the barrel and a breach end at the proximal end of the barrel; a handle connector connecting the barrel to a handle assembly; and the handle assembly having a free end and a connected end, the connected end operably connected to the handle connector; the handle assembly operable between a first position with the free end of the handle assembly pointing proximally and a second position with the free end of the handle assembly pointing distally.

Abstract: An adapter for an M240 machine gun to position the trigger housing assembly distally forward as well as an extended trigger housing assembly for an M240 machine gun and an M240 machine gun with the trigger housing assembly positioned distally forward from the proximal end of the receiver.

Abstract: An ammunition retaining feed tray for a firearm including a feed tray with a distal and a proximal end, a cartridge stop for alignment of an ammunition belt, at least one pawl opening, and a pawl assembly engagement; a pawl assembly connected to the pawl assembly engagement of the feed tray with the pawl assembly including at least one pawl operable to move within the at least one pawl opening of the feed tray and for engaging an ammunition belt.
