Abstract
An automatic or semi-automatic firearm including a trigger having a frame, at least one trigger sear extending from the frame, and a hammer having a hammer pivot axis, a head and at least one hammer sear disposed on a lateral side of the hammer between the hammer pivot axis and the head, wherein the frame includes a pivot axis and the at least one trigger sear includes a trigger sear surface, the at least one trigger sear extending from the frame such that the at least one trigger sear engages a corresponding one of the at least one hammer sear.
Claims8
An automatic or semi-automatic firearm comprising:
- a trigger having a frame;
- at least one trigger sear extending from the frame;
- a hammer having a hammer pivot axis, a head and at least one hammer sear disposed on a lateral side of the hammer between the hammer pivot axis and the head;
- wherein the frame includes a pivot axis and the at least one trigger sear includes a trigger sear surface, the at least one trigger sear extending from the frame such that the at least one trigger sear engages a corresponding one of the at least one hammer sear;
- a trigger hook extending from and pivotally coupled to the frame;
- a first spring connected to the frame for resisting rotation of the frame about the pivot axis;
- and a second spring disposed between the frame and the trigger hook for resisting rotation of the trigger hook relative to the frame;
- wherein the first spring and second spring are configured to work in series for dividing an application of a predetermined trigger pull force into a first and a second stage.
An automatic or semi-automatic firearm comprising:
- a receiver;
- a fire control group iocated at least in part within the receiver, the fire control group including a trigger having at least one trigger sear, a hammer having an elongated frame and at least one hammer sear extending from a lateral side of the hammer frame;
- wherein the at least one trigger sear extends along a portion of at least one lateral side of the hammer frame to engage a corresponding one of the at least one hammer sear, wherein the trigger comprises a frame and a trigger hook extending from the frame, the trigger hook being pivotally coupled to the frame;
- and wherein the trigger further comprises:
- a first spring connected to the frame for resisting rotation of the frame within the receiver;
- and a second spring disposed between the frame and the trigger hook for resisting rotation of the trigger hook relative to the frame;
- wherein the first spring and second spring are confidured to divide an application of a predetermined trigger pull force into a first and a second trigger pull stage.
