| 121 | Weapon system with short recoil impulse averaging operating group | US13562078 | 2012-07-30 | US08919238B2 | 2014-12-30 | David Steimke; Glenn Rossier |
| 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 extractor for a self-loading firearm is mountable on a breech block and is formed of a body having a hook at one end. The body is pivotally mounted via a pivot pin. A surface is positioned between the pivot pin and the hook. The surface is divided into at least two surface portions offset from one another. One of the surface portions has a plurality of step surfaces offset from one another. The step surfaces are used to fix the bar dimension of the hook. The invention also encompasses a slide on which the extractor is mounted, as well as a self-loading firearm having the slide. A method of fitting the extractor to the pistol or slide is also disclosed. | ||||||

| An extraction system for extracting a cartridge from a firing chamber of a firearm includes an extractor mounted within the firearm bolt which has a bolt head with a plurality of lugs proximate a bolt face, a cartridge recess extending axially inward from the bolt face, and an extractor aperture extending radially outward through one of the lugs. A spring aperture extends axially through the one lug and intersects with the extractor aperture. The extractor is slidably mounted within the extractor aperture and has a hook portion for coupling with the cartridge and a transverse spring bore extending through a mid-section of the extractor. The extraction system further includes an extractor spring having an anchor portion mounted about the outer surface of the bolt and a cantilever spring portion inserted through the spring aperture and into the transverse hole in the extractor, for resiliently biasing the extractor toward the cartridge recess. | ||||||
