摘要： System for a multi-caliber self-loading action. Specifically, the system is comprised of a multi-position locking assembly and a self-regulating gas assembly. The multiposition locking assembly is comprised of a bolt carrier, a spring, a bolt, a lock, and a cam assembly. The cam assembly will interface between the bolt carrier and the bolt to rotate the bolt through the bolt carrier. The lock will interface with the bolt, to lock the bolt in at least one locked position based on the caliber of the round inserted. The self-regulating gas assembly directs gas from the gas regulation to at least one piston cup, which will then cause the piston to act on the multi-position locking assembly.

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 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 6.8 SPC. 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： Methods and apparatus are disclosed for a locked machine gun that includes a casing, a barrel, a locking breech mechanism, an abutment and a quick change attachment. The locking breech mechanism has at least one locking body. The abutment holds the locking body or locking bodies of the locked breech mechanism. The quick-change attachment is used to facilitate the removal of the barrel and insertion and attachment of a new barrel. A first part of the abutment remains on the casing when the barrel is being changed, and a second part of the abutment is firmly connected to the barrel. The quick-change attachment is equipped to bring about a separation between the first part of the abutment remaining with the casing and the barrel with the second part. Also, the second part of the abutment has a curved section which controls the engagement of the breech mechanism in the abutment when the breech mechanism closes.

摘要： The invention concerns a firearm for receiving and firing a projectile. The firearm includes an integral casing having a barrel and a breech block receiving area to the rear of the barrel. A breech block is guided through the breech block receiving area by separated guide pins which project from the breech block into respective longitudinal track sections in the barrel. The guide pins are axially separated at opposite ends of the breech block and are circumferentially separated. The longitudinal track sections meet circumferential track sections. The guide pins in the circumferential track sections permit the breech block to be rotated. The breech block has a forward closed barrel position and a rearward open loading position. A breech mount around the breech block has a cam slot that extends longitudinally and into which a cam follower pin from the breech block projects. The breech mount is drawn forward by a spring and driven rearwardly by the gas pressure from detonation of a projectile leaving the barrel. To load a projectile in the barrel, the forwardly moving breech mount moves the breech block forward along the longitudinal track sections to the forward breech closed position and then rotates the closed breech block to the locked position in the circumferential track sections.
摘要翻译：本发明涉及用于接收和射击射弹的枪支。枪支包括一个整体的壳体，其具有枪管和枪管后部的后膛块接收区域。后枪块通过分离的引导销引导穿过后膛块接收区，引导销从后枪块突出到枪管中的相应的纵向轨道部分。引导销在后膛块的相对端轴向分离，并且沿圆周方向分开。纵向轨道段与圆周轨道段相交。圆周轨道部分中的引导销允许后膛块旋转。后膛块具有向前闭合的枪管位置和向后打开的加载位置。后膛周围的后膛安装有一个纵向延伸的凸轮槽，一个来自后膛的凸轮从动销突出。后膛安装件由弹簧向前拉动，并通过从离开枪管的弹丸引爆的气体压力向后驱动。为了将弹丸装载在枪管中，向前移动的后膛装置将后膛块沿着纵向轨道部分向前移动到前膛关闭位置，然后将闭合的后膛块旋转到周向轨道部分中的锁定位置。
