摘要： An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

摘要： A buttstock assembly configured to work in conjunction with a compact buffer assembly consisting of a buffer tube, spring and bolt carrier with an integral buffer is provided. The buttstock assembly, buffer tube and bolt carrier are configured to work with AR15/M16 type firearms and their derivatives. By incorporating the buffer onto the bolt carrier, which is used in conjunction with a buffer tube of reduced length, the overall length of the host firearm is reduced by approximately 3.2 inches. No permanent modification need be made to the host firearm in order to utilize the compact buffer assembly and buttstock assembly disclosed herein.

摘要： A Universal Custom Recoil Solution will comprise of, a provided Firearm or barrel, prismatic shaped shell housing mounted or connected to the Gas Block Base, a Gas Block Base with pathways to direct firearms gas pressure from firing bullet into device interior pushing a Counter Weight, and Spring to counter act the firearms recoil when fired. This device is fitted to or around a provided barrel where the Counter Weight and spring are mounted on and reciprocate from front to back of the systems interior volume. The systems main function is to create a counter balance to the firearms kinetic energy by providing a moving mass, to counter the recoil from the firearms action movement when firing. The gas pressure is also expelled and redirected allowing the device to cycle synergistically with the firearm actions.

摘要： A barrel assembly for use in a semiautomatic firearm, including a barrel and a takedown lever. A rear portion of the barrel includes a follower lug and a rear lug extending from an underside of the rear portion. The follower lug further includes a follower notch. A pin of the takedown lever includes a notch with a vertical face configured to contact a vertical face of the follower notch when the firearm is in the locked position. The rear lug is configured to be supported by a portion of a locking block of the firearm prior to firing and during a portion of the recoil period. The modifications to the barrel assembly result in increased dwell time and accuracy of the firearm.

摘要： A firearm impingement apparatus that includes a gas flow control member that is operable to provide incremental adjustment of gas flow within the gas block of the firearm impingement apparatus wherein the gas flow control member is configured to provide calibrated rotational movement thereof. The gas flow control member further includes a first portion, second portion and third portion contiguously formed. The first portion includes a plurality of longitudinal indentations circumferentially disposed thereon. The second portion has a diameter that is less than that of said first portion and said second portion. A mounting member is present adjacent an opening of a channel and includes a control pin biasly mounted therein that is operable to engage the gas flow control member. The control pin engages the longitudinal indentations to provide calibrated rotational movement of the gas flow control member.

摘要： An automatic handgun has an additional trigger mechanism and a sight. In one version, a draw bar in the butt is hinged to a rotatable fork and to the additional trigger, located on the left of the butt in an L-shaped groove. Upon rotating the fork the spring extends onto the left of the butt, and when the butt is closed onto a catch, the end of the fork grips the main trigger. Rotatable posts lie on the sight. Alternatively, a rotatable lever sits on the lower front of the breech. The lever has a post on which the additional trigger which fixes the horizontal and vertical positions is hinged, and is connected to the main trigger by a draw bar through the inside left of the breech. Shooting accuracy increases and the overall dimensions are reduced.

摘要： A firearm is described herein. The firearm comprises a receiver assembly adapted to receive a cartridge, a bolt assembly including a firing device operable to fire the cartridge, a barrel adapted to receive the projectile after the cartridge is fired, and a gas assembly including a gas tube. The receiver assembly includes an upper receiver portion, a lower receiver portion, and an upper receiver cover. The upper receiver portion defines a longitudinal axis, and an indexing slot operable to receive the gas tube. The upper receiver portion includes at least one integrated exterior track extending generally parallel to the longitudinal axis adapted to slidably couple with the upper receiver cover and a plurality of interior tracks extending generally parallel to the longitudinal axis adapted to slidably couple with the bolt assembly. The upper and lower receiver portions are pivotally connected to one another.
