Abstract: Gun and ammunition solutions which permit the use of High Explosive (HE) rounds and Armor Piercing Fin Stabilized Discarding Sabot (APFSDS) rounds in one weapon. A first system has a gun barrel chamber sized to receive the outer cases of both APFSDS and HE rounds. The chamber has a smooth rear section which abuts a front section having internal helical rifling. A HE round has an outer case with a length that is the same as the length of the smooth rear section of the barrel. A projectile held by the case has a rotating band on a rear end configured to engage the internal helical rifling in the chamber. A second system has a conventional smooth barrel and utilizes a HE round with an outer case having internal rifling in a forward section. A projectile held by the outer case has a circular band mounted to rotate about a rear end thereof to engage the internal rifling.

Abstract: A compact 50 caliber machine gun system which utilizes an original Browning rear-stripping ammunition link design. The chain-driven machine gun system features a delinker assembly configured to receive a belt of linked cartridges, separate each of the cartridge from the belt rearwardly, and feed each of the cartridges for firing. The delinking function is separated from the motion of the bolt assembly so as to reduce the overall length of the gun system. The receiver has a receiver mounting length RML from the rear base of each incoming cartridge in a belt of connected links to the rear end of the receiver that is less than 15 inches. A shuttle feed system is incorporated into the basic chain gun style mechanism which had been limited to a sprocket feed on all previous designs. An electronic anti-hangfire system uses a single proximity switch and the already existing parts and motions of the gun.
