摘要： The present invention is a gas block for use with a firearm that includes a tab covering the set screws and held in place by a pin that runs through the gas block body. The gas block body includes a slot around each set screw hole that allows the tab to be inserted into the gas block body. The tab provides several benefits over traditional gas block designs, including preventing the set screws from shifting or rotating during firing and allowing for easy installation and removal of the gas block without the need for specialized tools. The gas block is easily installed and removed, and the tab provides a secure and stable attachment point for the gas block. This gas block is an improvement in the field of rifle technology and is expected to find use in the firearms industry.

摘要： Various embodiments are directed to a barrel for a firearm. In various embodiments, a barrel comprises an inner surface defining a bore configured to guide a projectile as the projectile is propelled through the bore by pressurized gas; and a barrel gas port having a gas port depth extending between a port entrance defined by the inner surface of the barrel and a port exit, wherein the barrel gas port is configured to fluidically communicate with the bore and an action of the firearm; wherein the port entrance defines a length dimension defined parallel to a longitudinal axis of the barrel and a width dimension defined perpendicular to the length dimension; and wherein the length dimension of the port entrance is greater than the width dimension of the port entrance. Various embodiments are directed to a firearm comprising the exemplary barrel.

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.

摘要： A gas tube support system for a gas-actuated firearm contains an annular or bored housing for receipt of a gas tube therein, thereby securing the gas tube during operation of the firearm. At least one or more bores are drilled or formed within the annular or bored housing to provide an impingement of the gas tube as it extends through the annular or bored housing. One or more fasteners are threadedly or otherwise received within a corresponding one of one or more respective bores, thereby securing the gas tube within the annular or bored housing. A gas-actuated firearm containing the gas tube support system is also provided.

摘要： A gas operated firearm includes a barrel with an integrally formed gas block as one piece with the barrel. A barrel nut is assembled over the integral barrel and gas block, securing the rear barrel end to a firearm receiver. Gas tube or piston assembly and field replacement are enhanced, along with accommodation of increased size barrels and integral muzzle end devices, no longer limited by internal dimensions of separately added gas blocks.

摘要： A short-length, belt fed machine gun for convenient use includes: (A) a receiver having a length in the range of about 17.75 inches to about 20.3 inches, (B) a barrel assembly, and (C) a gas cycling assembly. A gas port of the barrel assembly has a width of between about 0.063 inches and 0.200 inches. The distance between a center of the gas port and the breach of the barrel is between about 7.605 inches and about 9.395 inches. The gas cycling assembly features a unique polymer kinetic energy dampener assembly located longitudinally rearward of the operating rod, which is useful in achieving a desired cycle rate of the gun (e.g., about 600 rounds per minute (RPM)) and in minimizing muzzle climb. A unique mounting bushing selectively, removably mounts to the gas cylinder in order to achieve a shortened gun with many of the advantages of conventional longer weapons.

摘要： A free float handguard for a firearm having a barrel includes a handguard body and a locking arrangement. The locking arrangement includes a barrel locker and a handguard locker. The barrel locker includes a first tubular locker adapted for coaxially coupling at a fixed end of the barrel, and a second tubular locker coaxially and rotatably coupled at the first tubular locker. The handguard locker has a rear portion coaxially coupled at the first tubular locker to prevent the handguard locker from being rotated therearound, and a front portion engaged with the second tubular locker to prevent the second tubular locker from being rotated around the first tubular locker, wherein a first end portion of the handguard body is coupled at the handguard locker for locking up the handguard body around the barrel in a free float manner.

摘要： A firearm includes a receiver, a forearm pivotally attached to a distal end of the receiver, and a barrel having a barrel extension. A proximal end of the barrel and the barrel extension are secured within the forearm such that the barrel and barrel extension are pivotable with the forearm relative to the receiver between a first assembled position and a second folded position. The firearm further includes a locking mechanism for securing the forearm, barrel, and barrel extension to the receiver in the first assembled position. The forearm, barrel, and barrel extension may be secured to the receiver in the first assembled position for use of the firearm, after which the firearm may be folded for storage and/or transportation.

摘要： An improved design of a two-piece gas block for a semi-automatic rifle barrel. The improvement consisting of integrated attachment features that allow for a smaller overall size and a more reliable fit around a rifle barrel. The integrated attachment features contain minimal hardware for assembly; therefore, easier to assemble and disassemble. These attachment features consist of built-in interlocking protrusions and recesses in each half of the two-piece gas block. When assembled, the interlocking protrusions and recesses radially secure both halves together around a rifle barrel. Once both halves are assembled, fitted pins are then inserted through the interlocking protrusions and recesses to secure both halves axially to each other.
