Abstract
A firearm system includes an upper receiver and a barrel mounted to the upper receiver and configured to fire projectiles. The firearm system further includes a bolt carrier arranged within the upper receiver for reciprocation during firing. The firearm system further includes a gas-piston system for transferring firing force to the bolt carrier for reloading after each projectile is discharged from the barrel.
Claims19
A firearm system, comprising:
- an upper receiver, a barrel mounted to the upper receiver;
- a bolt carrier arranged within the upper receiver for reciprocation;
- and a gas-piston system for transferring firing force to the bolt carrier for reloading, wherein the gas-piston system includes a piston shroud mounted to the upper receiver and a piston fixedly coupled with the bolt carrier, wherein the piston is arranged within the piston shroud to receive force from firing gas from the barrel for reciprocating movement, the piston operable between an extended position and retracted position to drive reloading via the bolt carrier, wherein the piston shroud is cantilevered from the upper receiver.
A firearm, comprising:
- a receiver including an upper receiver and a lower receiver;
