摘要： A firearm barrel has a gas channel in fluid communication with a gas port. The gas port diverts a portion of the gas produced when firing a round of ammunition into the gas channel. The gas channel extends longitudinally and substantially parallel to a longitudinal axis of the barrel to a gas block. The gas channel provides fluid communication between a gas block and a gas port located in different longitudinal positions on the barrel.

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： Implementations of the present invention relate to apparatuses, systems, and methods for firing a belt-fed closed-bolt firearm by delivering an impulse from an impulse source along a first axis to a firing pin on a second axis. The first axis and second axis are not coaxial, allowing the impulse source to be disposed away from and not in direct contact or alignment with the firing pin.
