摘要： A cartridge extracting tool for an AR-pattern firearm, such as the AR-15, M16, M4 and other variants, which employs a ratchet assembly with a charge handle claw that engages the firearm charge handle and buttstock, and applies tensile forces to withdrawn the charge handle, move the bolt carrier group, the bolt, and the jammed cartridge, to be ejected from the firearm.

摘要： An improved bolt and bolt carrier with integral gas key having an extension nozzle threadedly secured and pinned to the gas key for use with a direct gas operated firearm is provided. The extension nozzle is designed to receive a portion of the host firearm's gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pin's annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end. The extractor recess is constructed so that the face of the bolt is round and the adjacent lugs fully supported. The extractor engages approximately 17% more of a seated ammunition cartridge's rim as compared to the prior art AR15/M16 extractor. The result is an improved bolt and bolt carrier which provides for increased operational reliability.

摘要： A rotating bolt firearm may be configured to fire a .308 cartridge. However, the firearm may have a reduced weight in comparison to standard .308 rifles. The firearm may have many components typically used in a .223 rifle. The firearm may include a barrel extension with an extractor gap, which allows a .308 bolt to fit within a .223 sized barrel extension. The firearm may comprise an elongated magazine well in comparison to a .223 mil-spec rifle. The firearm may weigh less than 6.8 pounds with a 16-inch barrel, or less than 6.3 pounds with a 10.5 inch barrel.

摘要： The rifle system comprises a rifle and an ammunition round for operation with the rifle. The high pressure ammunition round further comprises a cartridge case having an outer wall wherein prior to firing of the ammunition round, the outer wall geometry of the cartridge case is devoid of features configured for interfacing with a mechanical extractor. The rifle further comprising a barrel chamber which fully supports a chambered cartridge case and a rear extraction mechanism for extracting a spent cartridge case through the rear of the barrel chamber.

摘要： A rife includes a receiver and a bolt body at least partially disposed in the receiver and including a body axis. The bolt body is discretely (1) rotatable about the body axis within the receiver and (2) axially slidable along the body axis. The rife also includes a bolt handle coupled to the bolt body so as to discretely (1) rotate with the bolt body about the body axis and (2) move with the bolt body along the body axis.

摘要： The present low pressure bolt carrier group is configured to maximize the axial force component, and minimize the radial force component, applied to both the bolt carrier and the bolt under low-pressure gas conditions, so that the two separate with greater acceleration and under greater force than a standard bolt carrier group when firing low-pressure ammunition. Thus, the present low-pressure bolt carrier group effectively and completely ejects the spent case and chambers the next round. These and other benefits are provided by the present low-pressure bolt carrier group comprising one or more of an increased piston bore diameter, an increased piston diameter, an increased flatness of the piston surface in the radial plane, and an increased stroke length of the piston by lengthening the cam pin slot. Therefore, the present low-pressure bolt carrier group solves long-persisting problems with standard bolt carrier groups when using low-pressure rounds.
