Abstract

A trigger assembly group of the type used with a rifle stock replacement system is provided. The trigger assembly group and may include a trigger assembly, including a trigger coupled to a trigger rod, a locking plate coupled to the trigger rod and a preload cylinder coupled to the locking plate. This in combination with the firing elements of the existing rifle may comprise a firing control mechanism. The trigger assembly group may also include a trigger block with a recess adapted to receive the trigger rod and the locking plate. A safety spool may be a part of the trigger assembly group and include a cross hole, which may be adapted to receive the preload cylinder when the safety spool is in a first position and not receive the preload cylinder when the safety spool is in a second position.

Claims

1. A trigger assembly group of the type used with a rifle stock replacement system, the trigger assembly comprising:

a trigger assembly, including a trigger coupled to a first end of a trigger rod and a trigger roller coupled to a second end of the trigger rod, a locking plate coupled to the trigger rod and a preload cylinder coupled to the locking plate;

a trigger block including a recess receiving the trigger rod and the locking plate, whereby the recess in the trigger block acts as a guide to restrict movement of the trigger rod; and

a safety spool rotatably coupled to the trigger block, the safety spool including a cross hole, the cross hole aligned with, and receiving the preload cylinder when the safety spool is in a first position and not able to receive the preload cylinder when the safety spool is in a second position, whereby when the safety spool is in the first position the trigger is able to move a distance relative to the trigger block and when the safety spool is in the second position, the trigger is able to move a lesser distance relative to the trigger block.

2. The trigger assembly group according to claim 1, wherein the preload cylinder is a threaded screw received in the locking plate.

3. The trigger assembly group according to claim 1, further comprising a preload locking screw received by the locking plate and positioned non-collinear with the preload cylinder.

4. The trigger assembly group according to claim 3, wherein the preload cylinder is substantially orthogonal to the preload locking screw, whereby the preload locking screw is adapted to provide a frictional force on the preload cylinder to restrict movement of the preload cylinder relative to the locking plate.

5. The trigger assembly group according to claim 1, further comprising a front trigger stop received by the trigger block and positioned to restrict the movement of the trigger assembly.

6. The trigger assembly group according to claim 5, further comprising a trigger stop locking screw received by the trigger block and positioned non-collinear with the front trigger stop.

7. The trigger assembly group according to claim 6, wherein the trigger stop locking screw is positioned substantially orthogonal to the front trigger stop, whereby the trigger stop locking screw is adapted to provide a frictional force on the front trigger stop to restrict movement of the front trigger stop relative to the trigger block.

8. The trigger assembly group according to claim 1, further comprising a safety spool pin received by the trigger block and adapted to provide a resistance to movement of the safety spool relative to the trigger block.

9. The trigger assembly group according to claim 8, wherein the safety spool pin includes a spring biased ball, the ball providing a frictional force on the safety spool.

10. The trigger assembly group according to claim 9, wherein the safety spool includes a detent hole adapted to receive a portion of the spring biased ball of the safety spool pin.

11. The trigger assembly group according to claim 1, further comprising a primary trigger safety, movably coupled to the a stock of the stock replacement system, the primary trigger safety coupled to an original safety of a rifle, the primary trigger safety including a safety arm accessible to a user and not obstructed by the stock.

12. A safety and trigger assembly group system for a firearm, comprising:

a trigger assembly, including;

a trigger coupled to a first end of a trigger rod;

a locking plate coupled to the trigger rod;

a preload cylinder coupled to the locking plate; and

a trigger roller on a second end of the trigger rod;

a trigger block including a recess receiving the trigger rod, thereby providing guided movement of the trigger rod and the trigger assembly; and

a safety spool rotatably coupled to the trigger block, the safety spool including a cross hole receiving the preload cylinder when the safety spool is in a first position and blocked from receiving the preload cylinder when the safety spool is rotated to a second position, whereby when the safety spool is in the first position the trigger is able to move a distance relative to the trigger block and when the safety spool is in the second position, the trigger is able to move a lesser distance relative to the trigger block.

13. The safety and trigger assembly group system according to claim 12, wherein the preload cylinder is a threaded screw received in the locking plate.

14. The safety and trigger assembly group system according to claim 12, further comprising a preload locking screw received by the locking plate and positioned non-collinear with the preload cylinder.

15. The safety and trigger assembly group system according to claim 14, wherein the preload cylinder is substantially orthogonal to the preload locking screw, whereby the preload locking screw is adapted to provide a frictional force on the preload cylinder to restrict movement of the preload cylinder relative to the locking plate.

16. The safety and trigger assembly group system according to claim 12, further comprising a front trigger stop received by the trigger block and positioned to restrict the movement of the trigger assembly.

17. The safety and trigger assembly group system according to claim 16, further comprising a trigger stop locking screw received by the trigger block and positioned non-collinear with the front trigger stop.

18. The safety and trigger assembly group system according to claim 17, wherein the trigger stop locking screw is positioned substantially orthogonal to the front trigger stop, whereby the trigger stop locking screw is adapted to provide a frictional force on the front trigger stop to restrict movement of the front trigger stop relative to the trigger block.

19. The safety and trigger assembly group system according to claim 12, further comprising a safety spool pin received by the trigger block and adapted to provide a resistance to movement of the safety spool relative to the trigger block.

20. The safety and trigger assembly group system according to claim 19, wherein the safety spool pin includes a spring biased ball, the ball providing a frictional force on the safety spool commensurate to the contact surface topography of the safety spool.

21. The safety and trigger assembly group system according to claim 20, wherein the safety spool includes a detent hole adapted to receive a portion of the spring biased ball of the safety spool pin.

22. The safety and trigger assembly group system according to claim 12, included in a stock assembly, the stock assembly further comprising a leveling screw positioned to contact a barrel, whereby the leveling screw is adapted to adjust the orientation of the barrel relative to the stock assembly.
