Abstract
In a firearm having a trigger assembly with a trigger nose, a hammer with a sear hook and a trigger notch, a disconnector and an automatic sear, an improvement including a notched bifurcating the sear hook of the hammer for receiving the disconnector in a past-cocked position. Further improvements include the trigger notch being offset rearwardly from a center of the pivot point resulting in a slightly changed angle away from an acute engagement angle with the trigger nose.
Claims18
In a firearm having a trigger assembly with a trigger nose, a hammer with a sear hook and a trigger notch, a disconnector and an automatic sear, wherein the improvement comprises:
- a notched bifurcating the sear hook of the hammer for receiving the disconnector in a past-cocked position;
- and
- the hammer pivots about a pivot point and the improvement further comprises the trigger notch being offset rearwardly from a center of the pivot point resulting in a slightly changed angle away from an acute angle of engagement with the trigger nose.
A trigger mechanism for use in a select fire M16 type firearm, the trigger mechanism comprising:
- a trigger assembly having a pivot for pivotally coupling the trigger assembly to a firearm;
- a disconnector having a pivot pivotally coupling the disconnector to the pivot of the trigger assembly;
- a hammer pivotable about a pivot point between a forward position, a cocked position and a past-cocked position, the hammer having a bifurcated sear hook defining a notch, the disconnector receivable within the notch in the past-cocked position.
A firearm comprising:
- a lower receiver;
- a trigger assembly having a pivot pivotally coupling the trigger assembly to the lower receiver;
- a disconnector having a pivot pivotally coupling the disconnector to the pivot of the trigger assembly;
- and
- a hammer having a pivot pivotally coupling the hammer to the lower receiver, the hammer being pivotable about a pivot point between a forward position, a cocked position and a past-cocked position, the hammer having a bifurcated sear hook defining a notch, the disconnector receivable within the notch in the past-cocked position.
A trigger mechanism for use in a select fire M16 type firearm, the trigger mechanism comprising:
- a trigger assembly having a pivot for pivotally coupling the trigger assembly to a firearm and a trigger nose;
- a disconnector having a pivot pivotally coupling the disconnector to the pivot of the trigger assembly;
- a hammer pivotable about a pivot point between a forward position, a cocked position and a past-cocked position, the hammer includes a trigger notch formed proximate the pivot point for receiving the trigger nose in the cocked position, the trigger notch being offset rearwardly from a center of the pivot point resulting in a slightly changed angle away from an acute engagement angle with the trigger nose.
A firearm comprising:
- a trigger assembly having a pivot for pivotally coupling the trigger assembly to a lower receiver and a trigger nose;
- a disconnector having a pivot pivotally coupling the disconnector to the pivot of the trigger assembly;
- and
- a hammer pivotable about a pivot point between a forward position, a cocked position and a past-cocked position, the hammer includes a trigger notch formed proximate the pivot point for receiving the trigger nose in the cocked position, the trigger notch being offset rearwardly from a center of the pivot point resulting in a slightly changed angle away from an acute engagement angle with the trigger nose.
