| 205 | Polymer gun operating handle | US320900 | 1989-03-10 | US4926739A | 1990-05-22 | David E. Byron |
| An automatic or semi-automatic pistol is made substantially of polymer materials. The pistol includes polymer upper and lower receivers and a polymer barrel attached to the upper receiver. The operating mechanism includes a bolt, block and a hammer, slidably mounted in the fixed upper receiver with the bolt and block and the hammer being separately springloaded. A gas operated link is positioned to rotate the pistol block from a locked to an unlocked position when actuated by gas from a fired cartridge. A gas port extends from the end portion of the barrel to one end portion of the gas operated link to move the link responsive to the gas pressure to thereby unlock the block so that the block, bolt and hammer can be operated by reaction to the gasses still in the weapon barrel. Other features include encasing the entire operating mechanism in an non-movable upper receiver with a removable trigger, and operating handle and having a cutoff switch to change the firing mode from self-loading semi-automatic action to a single shot action, and a counter-torque muzzle cap to counter the torque of the bullet spin, an automatic hammer safety to prevent firing if the action is not fully locked. | ||||||
| 206 | Bolt mechanism for fire arm | US96934 | 1987-09-14 | US4893547A | 1990-01-16 | Maxwell G. Atchisson |
| A locked breach, gas operated long action firearm capable of firing heavy caliber shotgun or rifle shells with substantially reduced recoil. The gas piston and bolt carrier assembly are supported for recoil movement along a single guide rod which extends the entire length of the gun, permitting a longer recoil path resulting in reduced impulse due to recoil. The guide rod has a noncircular or radially-assymmetrical cross-section mating with a corresponding opening in the gas piston, so that the bolt carrier assembly remains in alignment over the entire recoil path. Separate close-bolt and open-bolt embodiments are disclosed, and the open-bolt embodiment is selectively capable of firing either semi-automatic or full-automatic while permitting reliable cartridge feeding from a box or drum magazine. | ||||||
| 207 | Automatic rifle gas system | US897150 | 1986-08-15 | US4765224A | 1988-08-23 | Michael C. Morris |
| An M16-type automatic rifle is provided with an improved gas operating system. The tube extending forwardly from the bolt carrier key is of such length that it permanently mates with the aftwardly extending gas transfer tube as the bolt carrier key shuttles forward and aftward in operation. This arrangement minimizes fouling by combustion products from the firing of ammunition. Modifications to the gas transfer tube and barrel nut assembly accommodate the extended bolt carrier key tube and facilitate quick change of the barrel in the field with a standard tool. | ||||||

| 214 | Gas fired machine gun | US36421873 | 1973-05-25 | US3853035A | 1974-12-10 | DONOVAN J |
| A belt fed, gas fired machine gun has its gas port located just forward of the firing chamber so that the weight of its associated cylinder and piston is concentrated towards the rear of the gun. Power for operating the bolt, firing pin hammer and ammunition feed is stored in springs opposing movement of the piston in response to the gas firing pressure. The bolt has longitudinal movement only and is locked in chambered position by a cam actuated rotary latch which also performs the triggering function when the gun is operated in the full automatic setting. Interlinked ammunition is fed transversely through the gun by reciprocal tray pieces which are actuated by leaf springs whose return movement is imparted by return of the bolt ot its chambered position. Vertically slidable sear plates latchably control the firing pin hammer, which is mounted telescopically within the bolt. The gun is assemblable for either right hand or left hand operation.
