摘要： An annular piston system for a firearm comprises a barrel, a gas block assembly, a piston, and a spring. The barrel has multiple sections lengthwise, one of the sections having at least one gas port hole to vent gas from the barrel. The gas block assembly is disposed annularly around the barrel and is adjustable to control an amount of gas flowing out of the barrel through the at least one gas port hole. The piston is disposed annularly around the barrel and can move longitudinally along the barrel in response to being pushed by the gas flowing out of the barrel. The spring is disposed annularly around the third section of the barrel and coupled to the piston. The spring limits a distance that the piston can move longitudinally along the barrel when the piston is pushed to move by the gas flowing out of the barrel.

摘要： The embodiments described herein relate generally to a sleeve piston for operating the bolt carrier of a firearm. The sleeve piston can comprise a monolithic sleeve piston or it can comprise two or more sleeve-piston parts, thereby evenly distributing the reciprocating mass of an auto-loading firearm about its barrel, minimizing muzzle rise. The sleeve piston can further be coupled to the bolt carrier by two or more operating rods, thereby reducing the tipping force or off-axis torque experienced by the bolt carrier during firearm operation. The sleeve piston can also reciprocate in a sleeve gas block coupled to a barrel, thereby helping to transfer heat away from the barrel. The sleeve piston embodiments of the present invention provide a balanced and compact operating mechanism that is ideally suited for rifles, carbines, and personal-defense weapons.
摘要翻译：本文所述的实施例大体上涉及用于操作枪支的螺栓支架的套筒活塞。套筒活塞可以包括一个整体的套筒活塞，或者它可以包括两个或更多个套筒 - 活塞部件，从而使自动装载枪支的往复运动物质均匀分布在其筒体周围，从而最小化枪口上升。套筒活塞还可以通过两个或多个操作杆联接到螺栓承载件，从而减少在枪械操作期间由螺栓承载件承受的倾覆力或离轴扭矩。套筒活塞还可以在与筒体相连的套筒气体块中往复运动，从而有助于将热量从筒体传送出去。本发明的套筒活塞实施例提供了平衡和紧凑的操作机构，其理想地适用于步枪，卡宾枪和个人防御武器。

摘要： A bolt carrier for use with the AR15/M16 family of firearms is provided. The bolt carrier includes an integrally formed carrier key and spherical strike face surrounded by a cylindrical counterbore made with a downward angle to act against the tilting force imparted by the operating rod of the firearm's gas operating system. The outer surface of the carrier includes upper and lower running rails that all extend fully to the front face of the carrier to lengthen the carrier's rail support or bearing surfaces against the receiver. To improve the robust operation of the firearm in over the beach operations, the bottom and rear of the receiver extension has drain holes formed through which water is forced out of the receiver extension by the reciprocating action of the bolt carrier when the weapon is fired.
摘要翻译：提供了与AR15 / M16系列枪支一起使用的螺栓支架。螺栓托架包括一体形成的托架键和由朝下制成的圆柱形沉孔包围的球形冲击面，以抵抗由枪支气体操作系统的操作杆施加的倾斜力。载体的外表面包括上下运行轨道，其全部完全延伸到载体的前表面，以将载体的轨道支撑件或支承表面延伸抵靠接收器。为了改善海上作业中枪支的稳健操作，接收器延伸部的底部和后部具有形成的排水孔，当武器被射击时，水通过螺栓承载件的往复作用被迫离开接收器延伸部分。

摘要： A firearm comprises a gas drive for actuating loading and/or firing means in response to the discharge of a round, wherein the gas drive comprises a pneumatic cylinder and a pneumatic piston, the cylinder chamber communicates with the barrel bore through at least one transverse bore in the barrel, and powder gas is adapted to enter said cylinder chamber through said transverse bore and to move said cylinder and piston relative to each other against the force of a return spring. In order to provide a gas drive which is particularly simple and functionally reliable, light in weight and compact, the barrel is provided with a collar or the like, which constitutes a stationary pneumatic piston, and the pneumatic cylinder consists of a sliding sleeve, which surrounds the collar and is longitudinally displaceable between stops.

摘要： This invention relates to firearms of the type disclosed in my prior U.S. Pat. No. 3,424,053, granted Jan. 28, 1969, in which the principal parts such as actuating sleeve, receiver, frame and breechblock are made from cylindrical extruded metal tubing and metal rods. The combination of a cylindrical actuating sleeve, breechblock, frame, receiver, floating power cylinder, ratchet counter firing mechanism and other incidental parts are used to form a new action for automatic firearms.This new action consists of a cylindrical sleeve carrying a floating power cylinder and functioning as an extractor port seal, breechblock stop and to actuate the ratchet firing counter. The above-mentioned parts and the breechblock lend themselves to manufacture by the use of automatic lathes and screw machines.The use of an actuating sleeve and floating power cylinder results in a favorable mass ratio, which results in a reliable firearm.

摘要： An assembly for directing propellant gas to an action of a firearm includes a barrel and a gas block. The barrel has a plurality of gas ports that communicate with the bore of the barrel. The barrel and the gas block define a passage that receives pressurized propellant gas from the bore by way of the barrel gas ports, and directs the propellant gas to a gas port of the gas block. The plurality of barrel gas ports and the passage act as a manifold in which the propellant gas is taken from multiple locations within the barrel, combined into a single flow, and directed into the gas block via the gas block gas port. The pressurized gas is then routed to an action of the firearm by way of a gas tube and a gas key.
