Benefits of technology

[0007]By virtue of the tip of the trigger contacting tip of the trigger travel adjustment insert contacting the trigger tang, a lifting force is applied to elevate the trigger tang towards the safety selector cam within the fire control cavity. Accordingly, the trigger is rotated relative to the hammer to reduce the depth and engagement of the trigger sear into the hammer sear notch within which the trigger sear is received prior to the trigger being pulled. Therefore, both the trigger and the trigger sear are required to travel a shorter distance before the trigger sear is fully disengaged from the hammer sear notch to permit the hammer to be released and the weapon to be fired. The shorter pull distance of the trigger results in improved consistency and better shooter accuracy.

Problems solved by technology

Excessive backward travel, beyond the point of trigger reset, is undesirable and only serves to lengthen trigger pull distance and add to inconsistency of trigger function.

Embodiment Construction

[0013]A trigger travel adjustment insert 10 according to a preferred embodiment of this invention is described while referring concurrently to FIGS. 1-5 of the drawings. The advantages of this invention are particularly applicable to a rifle such as that shown in FIG. 1 which generally includes upper and lower receivers 3 and 5 detachably connected at one end thereof to a barrel and handguard 7 and at the opposite end to a buffer tube 1 and a shoulder rest or butt 9. By way of example only, the trigger travel adjustment insert 10 can be used with the AR15, M16, AR10, and similar weapons platforms. It is to be understood that the trigger travel adjustment insert 10 can also be used in handguns that are based on the stated platforms.

[0014]As is best shown in FIG. 2, the trigger adjustment insert 10 has an elongated screw threaded body 12 so as to be capable of replacing a conventional threaded grip screw that is typically used to detachably connect the hand grip 14 of the rifle or pis...

Abstract

A threaded trigger travel adjustment insert to be located in the existing grip screw hole of a lower receiver commonly associated with a rifle or a pistol to connect the hand grip to the receiver. The trigger travel adjustment insert has a trigger contact tip at one end thereof for receipt within the fire control cavity of the lower receiver at which to contact the trigger tang of the weapon. Rotating the threaded trigger travel adjustment insert through the grip screw hole causes the trigger contact tip of the insert to elevate the trigger tang resulting in a corresponding reduction in the overlap between the trigger sear and the hammer sear notch prior to the trigger being pulled. Accordingly, the distance traveled by the trigger through the fire control cavity after the trigger is pulled and released is advantageously shortened to improve trigger predictability and reliably, thereby facilitating improved accuracy.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a trigger travel adjustment insert to be located in the existing grip screw hole of a lower receiver that is commonly associated with the AR 15, or similar weapons platforms. The trigger travel adjustment insert has a trigger contact tip at one end thereof which is located in contact with the trigger, thereby establishing the home position to which the trigger will return after the trigger has been pulled to fire the weapon. Adjustment of the trigger travel adjustment insert towards the trigger correspondingly reduces the length of the trigger pull required to release the hammer and fire the weapon. The trigger travel adjustment insert facilitates improved shooter accuracy by promoting predictable and reliable hammer release and subsequent discharge of the weapon.[0003]2. Background Art[0004]In the case of a shooter aiming and firing a rifle or a pistol, accuracy is significantly influenced by ...
