A weapon system is provided. The weapon system includes a receiver and an operating group. The operating group includes a barrel extension at least partially housed within the receiver and arranged to axially translate relative to the receiver; an operating rod (op-rod) assembly arranged to axially translate within the barrel extension; and a bolt assembly arranged to axially translate within the barrel extension. The system further includes a gas accelerator coupled to the barrel and the op-rod assembly; a buffer assembly including a self-centering spring and a hydraulic piston assembly having a first end coupled to the receiver and a second end coupled to the barrel extension; and a feeder coupled to the receiver and configured to provide the round to the operating group. |

A novel mechanism for moving a gun bolt toward and away from a firing chamber of a barrel assembly having movement relative to a receiver in a cartridge-firing weapon, having a camming channel formed in the receiver of the weapon, uses a rack member having an end coupled to the gun bolt and moving substantially linearly with the gun bolt toward and away from the chamber. A gear train has a housing affixed to the moving barrel assembly; an input member moves in the camming channel responsive to barrel assembly movement, to cause an output member to move the rack member and attached gun bolt toward and away from the chamber with substantially-linear displacement, velocity and acceleration greater than the associated displacement, velocity and acceleration of the moving barrel assembly with respect to the weapon receiver. |

A heavy support weapon, for example, of 30 mm caliber, designed for firing from conventional machine gun mounts without undue recoil loads transferred to the gun mount. The weapon is designed for first round accuracy whether in the automatic open bolt or semi-automatic closed bolt mode. The weapon 10 includes a barrel 13 joined to a barrel yoke 21 in a receiver 14 aft of a front housing assembly 15. The recoil system includes a main recoil spring 30, a secondary spring 23, a buffer group including rods 60, springs 61 and plate 63. A slide bolt assembly 40 includes a slide 41, a bolt 42, a face 43, bolt face levers 44 and actuating pins 45, all within the receiver 14. The bolt face 43 is driven vertically by the bolt face levers 44 to receive a new round, load it and remove and discharge a spent casing. The slide bolt assembly 40 travels forward and aft during the firing cycle. On rearward travel it is accelerated rearward by accelerator 70 until reaching the buffer group and transfers its kinetic energy to the buffer group which in turn transfers that energy to the barrel 13 and the recoil spring 30 where it is absorbed without transferring the impact loading to the weapon mount. |
