Abstract
A firearm including a barrel having a chamber and an integrally formed upper receiver having a passageway, an accessory rail extending the complete length of the upper receiver, and a guidance feature extending along the passageway. The firearm also includes an operating rod having an anti-bounce mechanism, a bolt that is rotated counter-clockwise to lock against the chamber, a bolt carrier having a safety extension disposed below the bolt that prevents a hammer from striking a firing pin until the bolt is locked against the chamber, a lower receiver, a recoil spring assembly, and a fire control group. The bolt includes a polymer spring that biases a sliding extractor against the base of a cartridge. The sliding extractor is disposed at an angle ranging from thirty degrees to fifteen degrees on the bolt face to provide a low ejection angle from the firearm.

30. :
- A firearm for firing a cartridge, the cartridge including a base, the firearm comprising;
a barrel comprising a chamber;
an integrally formed receiver comprising a longitudinal axis, a passageway extending generally parallel to the longitudinal axis, and a guidance feature extending into the passageway and along the passageway generally parallel to the longitudinal axis, wherein the barrel is attached to the receiver;
a bolt carrier guided by the guidance feature of the receiver, the bolt carrier comprising an operating rod slot that is open at an end of the bolt carrier and a cam slot, wherein the cam slot extends from the operating rod slot;
a bolt connected to the bolt carrier, the bolt comprising a protrusion extending from the bolt, wherein the protrusion is movable within the cam slot, wherein the bolt further comprises a bolt face, a polymer spring, and a sliding extractor, wherein the polymer spring biases the extractor against the base of the cartridge to retain the base of the cartridge against the bolt face, wherein the bolt carrier further comprises a safety extension disposed below the bolt;
an operating rod comprising a piston and a foot, wherein the foot is disposable within the operating rod slot of the bolt carrier to prevent the bolt from separating from the bolt carrier and to connect the operating rod to the bolt carrier, wherein the operating rod further comprises an anti-bounce mechanism;
a firing pin guided by the bolt;
a fire control group connected to the receiver, the fire control group comprising a hammer, wherein the safety extension of the bolt carrier prevents the hammer from striking the firing pin until the bolt is locked against the chamber.
