摘要： A semi-automatic or automatic rifle comprising a barrel attached to and upper receiver and including a compressible bolt carrier extension system. The compressible bolt carrier extension system includes a bolt carrier, an extension spring, two pins, and a reciprocation bolt carrier extension piece. As a whole, the compressible bolt carrier extension system makes possible the use of elongated upper and lower receivers to be used for chambering long-action or other center fire cartridges for use with AR rifles such as the M-16, and M4 etc., eliminating the need for any buffer or buffer tubes other than those commercially available. A further advantage of the compressible bolt carrier extension system is the reduction of felt recoil as the system fully loads during the recoil stroke as it pushes against the buffer absorbing additional recoil energy. The system can be incorporated into firearms using a variety of cartridges.

摘要： A propellant gas energized firearm has a gas supply passage conducting propellant gas from a gas port of a firearm barrel to an actuating chamber of a bolt carrier and bolt group having an actuating chamber. A gas key member is mounted to the bolt carrier and defines a part of the gas supply passage and has an opening intersecting the gas supply passage. A gas adjustment member is selectively moveable within the gas adjustment opening and has a gas interruption member projecting into the gas supply passage. The gas adjustment member is rotatable within the gas adjustment opening for selectively positioning the gas interruption member within the gas supply passage to selectively control the characteristics of the propellant gas delivery to the actuating chamber of the bolt carrier and bolt group.

摘要： Provided in one aspect is an annular gas ring within or adjacent a barrel to increase the efficient transfer of pressurized gas to one or more gas ports, which may communicate the high-pressure gas to a piston to cycle the action of the firearm. Provided in another aspect are gas ports may adjacent the chamber, which may communicate pressurized gas from near the chamber to distally-extending gas tubes that communicate the pressurized gas to a distally located piston to cycle the action. A modular gas system is provided comprising a coupler that couples a barrel with a chamber and forms there-between an annular gas ring with ports that communicate pressurized gas to separate longitudinally-extending cylindrical gas tubes that feed into a gas block that supports the barrel and forms the cylinder for the piston.

摘要： A gas flow volume control apparatus includes an adjustable gas block and a securing member as the securing member fixes the adjustable gas block onto a barrel of a firearm. The adjustable gas block is in fluid communication with the barrel so that generated gas of a propelling bullet can be recycled within a gas-operated reloading system. The generated gas is rerouted from the barrel to the gas-operated reloading system through a gas flow channel and a gas-tube channel of the adjustable gas block. An adjustment channel of the adjustable gas block also allows a user to control the rerouted amount of generated gas in order to optimize the performance of the firearm.

摘要： A gas piston retrofit assembly is provided for a firearm having a bolt assembly mounted within a receiver, a barrel extending forward from the receiver, and a front sight block mounted on the barrel. The retrofit assembly includes a gas tube extending into the front sight block fluidly connected with the barrel, a piston cylinder having an arcuate-shaped piston chamber fluidly connected to the gas tube, a piston including an arcuate-shaped piston head extending forward from a piston body and telescopically received in the piston chamber, and including a piston rod extending rearward from the piston body and dimensioned and configured to extend into the receiver for engaging with a bolt assembly within the receiver. Upon firing a round of ammunition, pressurized gas within the barrel enters the piston chamber to move the piston rearward, for cycling the bolt assembly. A method of using the same is also disclosed.
