Firearm having a tool-less trigger pull adjustment
View Patent ↗A firearm with a tool-less adjustable trigger pull. The adjustment may be facilitated with a thumb rotatable wheel for tool-less tension adjustment of a trigger tension spring. The rotatable wheel may be accessed by snapping a trigger guard away from a stock of the firearm. Accordingly, the force required to actuate the trigger can be adjusted to the user's preference without having to remove the trigger assembly from the stock, and without need for external tools or accessories.
1. A firearm, comprising:
a stock;
a trigger assembly mounted to said stock and including a trigger pull adjustment for adjusting a pull force required to actuate a trigger of said trigger assembly, said trigger pull adjustment including a thumbwheel for adjustment of said pull force without an external tool;
a removable trigger guard assembly attachable to said stock without a tool and without fasteners, said trigger pull adjustment being accessible by removal of said removable trigger guard assembly.
2. The firearm of claim 1 , wherein said thumbwheel is positioned below said stock.
3. The firearm of claim 1 , wherein said trigger assembly includes a stop lever, said trigger not actuatable to release a firing pin of said trigger assembly without the stop lever first being pulled.
4. A trigger assembly, comprising:
a trigger including a finger pull portion and a pull adjustment platform portion; and
a trigger pull adjustment, including:
a return spring that extends from said pull adjustment platform portion;
a thumbwheel coupled to said return spring and configured to vary a pre-loaded compression of said return spring against said pull adjustment platform portion; and
a post engaged with said thumbwheel, said thumbwheel being adjustable along said post,
wherein:
said return spring contributes to a trigger pull force required to actuate said trigger;
adjustment of said thumbwheel along said post varies said pre-loaded compression of said return spring against said pull adjustment platform, thereby varying said trigger pull force; and
said thumbwheel is configured for positioning along said post with a thumb or finger of a hand.
5. The trigger assembly of claim 4 , wherein said thumbwheel is threadably engaged with said post.
6. The trigger assembly of claim 4 , wherein said post extends parallel to said return spring.
7. The trigger assembly of claim 6 , wherein said return spring is a coil spring and said post extends into an inner diameter of said coil spring.
8. The trigger assembly of claim 4 , comprising:
a pin about which said trigger is rotatable; and
a stop lever rotatable about said pin, said stop lever being configured to selectively enable actuation of said trigger by rotating said stop lever about said pin.
9. A method for adjusting a pull force required to actuate a trigger on a firearm, comprising:
disconnecting a trigger guard from a stock of said firearm to access a trigger pull adjustment, said trigger guard being secured to said stock without use of a fastener, said trigger guard being removable without use of a tool; and
adjusting a thumbwheel on said trigger pull adjustment to vary said pull force required to actuate said trigger.
10. The method of claim 9 , wherein the step of adjusting said thumbwheel includes rotating said thumbwheel.
11. The method of claim 9 , comprising:
after the step of adjusting said thumbwheel, connecting said trigger guard to said stock without use of a fastener or a tool.
