Abstract
A gas-operated autoloading firearm mechanism has a compression chamber fluidly interfacing a barrel via a gas takeoff and a piston within the compression chamber which is urged rearwardly by combustion gas entering the compression chamber from the barrel during firing. The piston acts on a round carrier which moves relative to a bolt carrier. As such, the mechanism urges a round carrier rearwardly to strip a new round from the magazine and move the new round rearward behind a firing chamber. The mechanism urges a bolt carrier rearwardly away from the firing chamber to expel a spend case and to align the new round between a bolt assembly of the bolt carrier and the firing chamber so that, when the bolt carrier rebounds forward, the new round enters the firing chamber.

A gas-operated autoloading firearm mechanism comprising:
- a compression chamber fluidly interfacing a barrel via a gas takeoff;
- and
- a piston within the compression chamber which is urged rearwardly by combustion gas entering the compression chamber from the barrel during firing to:
- urge a round carrier rearwardly to:
- strip a new round from the magazine;
- and
- move the new round rearward behind a firing chamber;
- and
- urge a bolt carrier rearwardly away from the firing chamber to:
- expel a spend case;
- and
- to align the new round between a bolt assembly of the bolt carrier and the firing chamber so that, when the bolt carrier rebounds forward, the new round enters the firing chamber and wherein the round carrier moves relative to the bolt carrier.
