Abstract
A reciprocating bolt assembly has delayed blowback and a firing pin block. Features prevent out-of-battery firing, when the bolt assembly is not fully engaged to the firing chamber or barrel face, a movable member within a bolt body functions as a blocking member that blocks the firing pin and prevents the firing pin from striking a cartridge. In embodiments, the firing pin has two stop portions that the movable member can engage depending on the cycle status of the firearm. A reverse cam mechanism associated with the firing pin blocking provides a resistance to and delays blowback.

1-23. (canceled)
A trigger assembly of a semi-automatic firearm for firing rimfire ammunition, the trigger assembly comprising:
- a hammer rotatable about a first axis, the hammer including structure defining a capture feature and a lip portion;
- a firing trigger rotatable about a second axis, the firing trigger comprising a first finger hook and a sear portion releasably coupled to the hammer;
- a firing trigger return spring configured to urge the firing trigger toward a battery position, wherein the firing trigger return spring is adjustable to alter a spring force applied to the firing trigger;
- an arrestor rotatable about the second axis, the arrestor comprising a claw portion configured to engage with the lip portion of the hammer;
- a safety trigger rotatable about the second axis, the safety trigger comprising a catch configured to, when the safety trigger is in a battery position, arrest the capture feature of the hammer as the hammer rotates to prevent discharge of the semi-automatic firearm;
- and
- an arrestor return spring configured to urge the arrestor toward a position configured to engage with the lip portion defined by the hammer.
A semiautomatic firearm for firing rimfire ammunition, comprising:
- a barrel defining a chamber for receiving and firing a rimfire cartridge;
- a receiver operatively coupled to the barrel;
- a bolt assembly operatively coupled to the receiver and comprising a firing pin configured to fire the rimfire cartridge;
- and
- a trigger assembly configured to actuate the firing pin, the trigger assembly comprising:
- a hammer rotatable about a first axis and configured to contact the firing pin when firing the rimfire cartridge, the hammer including structure defining a capture feature and a lip portion;
- a firing trigger rotatable about a second axis, the firing trigger comprising a first finger hook and a sear portion releasably coupled to the hammer;
- a firing trigger return spring configured to urge the firing trigger toward a battery position, wherein the firing trigger return spring is adjustable to alter a spring force applied to the firing trigger;
- an arrestor rotatable about the second axis, the arrestor comprising a claw portion configured to engage with the lip portion of the hammer;
- a safety trigger rotatable about the second axis, the safety trigger comprising a catch configured to, when the safety trigger is in a battery position, arrest the capture feature of the hammer as the hammer rotates to prevent the hammer from contacting the firing pin;
- and
- an arrestor return spring configured to urge the arrestor toward a position configured to engage with the lip portion defined by the hammer.
