A continuous shooting device includes a shooting body having a driving chamber and a chain hole in connection with the driving chamber, a belt chain assembly, an arrow driving assembly and a string firing assembly. The belt chain assembly is for driving the arrow chain, to move along the chain hole, the arrow driving assembly has a push arm for pushing an arrow on the arrow chain to escape from the arrow chain, a string of the string firing assembly is for pushing the belt chain assembly, a part of the driving assembly is mounted in the driving chamber, the driving assembly includes a track rod assembly fastened in the driving chamber, and a sliding member assembly slidable along an arrangement direction of the track rod assembly. The sliding member assembly has a carrying portion for clipping a string, and a pushing portion for pushing the push shaft.

Implementations of ammunition round counting devices may include: a first module and a second module hingedly coupled together, the first module and the second module configured to open and close around a belt of ammunition; a counter module including one of at least two light emitting diodes (LEDs) and at least two light sensors or at least two proximity sensors; a display screen on an outside of the first module; and a battery pack operatively coupled with the counter module. The counter module may be configured to count a number of rounds in the ammunition belt that pass through the first module and the second module.

A firearm is adapted to use linked ammunition, either as a stand-alone firearm or a kit for the firearm. A belt feed lever is actuated by a drive roller in communication with the firearm recoil assembly. The belt feed lever turns a vertical drive shaft. The drive shaft operates a lower pawl, the manipulation of which advances the next round of linked ammunition to a position above the feed ramp. The firearm feeds linked ammunition upside down, that is, with the links facing downward. A box mount is fitted in place of the standard box magazine when the firearm is used to fire linked ammunition, thereby providing a feed tray and feed follower. To convert back to the use of ammunition fed from magazines, the user need only remove the box mount and replace it with a traditional box magazine.

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.

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 slidably received in the receiver and the barrel extension is coupled to a hydraulic buffer assembly located below the barrel extension. The hydraulic buffer assembly is configured and arranged to arrest rearward movement of the barrel assembly when the rifle is fired. An op-rod spring is coupled to an op rod extending that can be actuated by a gas piston assembly on the barrel. The op-rod spring is configured and arranged to arrest rearward movement of the bolt assembly.
