Publication number: 20240035768Abstract: Disclosed is an extractor for an autoloading firearm, the extractor having an extractor body extending a proximal end portion to a distal end portion. A knuckle is between the proximal end portion and the distal end portion and defines a pin opening extending crosswise through the extractor, where the pin opening has an elongated shape. During rearward movement of the bolt after firing, the elongated opening enables the extractor to shift downward and/or forward so that part of the extractor contacts the bolt, thereby preventing the extractor from pivoting about the extractor pin.Type: ApplicationFiled: July 17, 2023Publication date: February 1, 2024Applicant: Sig Sauer, Inc.Inventors: Lucas P. Gagne, Aaron C. Sakash, Bryan C. Dustin, David L. Steimke

Patent number: 11022389Abstract: Techniques and architectures are disclosed for a gas operating system for a firearm. The system includes a barrel having a bore including a rifled portion. Attached to the barrel is a gas block. Located distally of the rifled portion of the bore is a gas expansion chamber in fluid communication with the bore and the gas block. In some examples, the gas expansion chamber includes a diameter at least twice the bore diameter. The gas block of the gas operating system, in some examples, includes a piston, where in response to receiving gases from the gas expansion chamber, the piston cycles the gas operating system.Type: GrantFiled: January 22, 2019Date of Patent: June 1, 2021Assignee: SIG SAUER, INC.Inventors: Douglas Aubin, David Michael Wilkes, Aaron C.
