| A training barrel for a normally breech-locked, blow-back operated firearm omits the breech-locked function and replaces it with a barrel positioning device attached to the barrel. A spring provides the force to displace the barrel rearwardly to properly position it to receive the next cartridge being loaded. | ||||||

| 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 weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring. | ||||||

| An onboard combustion-gas-powered engine supplies power to a paintball marker or other projectile launcher by generating gas pressure pulses for propelling paintballs and other projectiles. The combustion gases produced by the engine can be allowed to rise in pressure within a confined volume of space before being released through a valve into a barrel for applying enhanced pressure pulses to the projectiles. A loading system is linked to a combustion accelerating system for automatically loading projectiles into the launcher. | ||||||

| A recoil-reducing weapon may include a housing and a receiver translatably disposed in the housing. A barrel may have one end fixed to the receiver and be translatable with respect to the housing. A spring stop may be fixed to the barrel forward of the housing and a spring may be disposed between the spring stop and a front of the housing. An operating group with a gear rack may be translatably disposed in the receiver. A longitudinal member may have one end fixed to the operating group. A counter-mass may have a second gear rack and an opening therein for receiving the longitudinal member. A second spring may be disposed around the longitudinal member. One end of the second spring may bear against the operating group and another end of the second spring may bear against the counter-mass. A pinion gear may be rotatably fixed to the receiver and operable to mesh with the gear rack and the second gear rack. | ||||||

| 13 | Gas operated automatic weapon | US20679 | 1979-03-15 | US4270437A | 1981-06-02 | John S. Donovan |
| A belt-fed, gas operated automatic weapon of a type in which the gas pressure developed in the bore is ported just forward of the chamber and utilized to compress a system of opposing spring sets which in turn operate the various mechanisms involved in the automatic or semi-automatic functioning of the weapon. Symmetrically arranged dual power cylinders operated by the gas pressure compress all of the springs in the opposing spring sets by engagement with a sliding carriage. Bolt locking is carried out by a separate oscillating cam-operated bolt latch element cooperating with a shoulder recess formed in the periphery of the bolt, with an arrangement for reducing the bolt locking mechanism forces during the unlocking interval. Manual actuation is enabled by movement of a slider. The bolt is automatically latched open in some modes of operation. A particular interlinked ammunition belt construction is disclosed to separate each link from the belt after passing beyond the bolt. | ||||||

| 18 | Short recoil fire-arm | US13051334 | 2011-03-18 | US08316754B2 | 2012-11-27 | Giovanni Gugliada |
| The present invention relates to a short recoil firearm (1) comprising a main body (2); a barrel (7) slidingly mounted on the main body (2) and movable between a forward percussion position and a backward recoil position; a slider (17) slidingly mounted on the main body (2) and movable between a forward position of closure of the barrel (7) and a backward stop position. The firearm (1) further comprises a plurality of cylindrical rollers (22) operatively connected to a spirally wound tape spring (26). The cylindrical rollers are movable between a first configuration, in which they lie mutually side by side between the slider (17) and the barrel (7), to prevent the relative movement thereof and to allow the integral displacement of same, and a second configuration, in which they lie in a recovery chamber (27). During passage from the first configuration towards the second configuration, the displacement of the barrel (7) opens an access (27a) for entrance of the cylindrical rollers (22) into the recovery chamber (27), causing disengagement between the barrel (7) and the slider (17). During passage from the second configuration towards the first configuration, the tape spring (26) brings the pushing elements (22) back to the first configuration through said access (27a). | ||||||
