| 193 | Gun part with integral spare extractor | US15836981 | 2017-12-11 | US10151549B1 | 2018-12-11 | Daniel Simpson Batchelor |
| A gun part with integral spare extractor has a planar element having a first periphery and form adapted to provide a first gun part function, the planar element including an integral and detachable removable element having a periphery adapted to provide a second gun part function, and at least a portion of the periphery of the removable element being defined by an elongated articulated opening defined in the planar element such that the removable element is connected only by a limited portion that is breakable without affecting the utility of the planar element and the removable element. The removable element may be positioned away from the first periphery such that an enclosed aperture is defined by the opening upon removal of the removable element. The opening may be an articulated cut of consistent width. The removable part may be connected to the planar element by only a single span. | ||||||

| 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. | ||||||

| 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. | ||||||

| 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 firearms gas operating system. The firing pin retaining pin is oriented so as to expose its widest profile to the firing pins annular flange, increasing its service life. The bolt has a plurality of lugs extending from its forward end and an extractor recess. The extractor recess is constructed to accommodate an enlarged extractor claw while not undercutting the bolt lugs adjacent thereto. The extractor engages approximately 57% more of a seated ammunition cartridges rim as compared to some prior art AR15/M16 type extractors used with automatic firearms chambered in 6.8SPC. The result is an improved bolt and bolt carrier which provides for increased operational reliability. | ||||||

| 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. | ||||||

| A firearm includes a bolt mechanism with a bolt configured to receive a firing pin assembly and a bolt head assembly. The bolt head assembly includes a pivoting bolt head and an extractor. The extractor is positioned relative to the bolt such that substantially all forces applied by the extractor to the bolt mechanism are reacted within the bolt head assembly. A biasing member or element can urge a claw portion of extractor towards a distal end of the bolt head. | ||||||

| Firearm ejectors and receivers and firearms including such firearm ejectors are disclosed. An example ejector for a firearm includes a body including a projection extending therefrom, the ejector to be movably coupled to a receiver of the firearm to enable the projection including an engagement surface to be disposed in a movement path of a breechblock, the engagement surface to be engaged by a cartridge casing during a recoil process to enable the cartridge casing to be ejected from the firearm; and a spring to bias the body relative to the receiver, the body to be movably relative to a longitudinal axis of the receiver upon impact with the cartridge. | ||||||

| 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. | ||||||
