Bullpup conversion kit for firearm

1. A bullpup conversion kit for a firearm, comprising:

a housing;

a forward trigger assembly;

a trigger actuator;

a firearm safety interlock that engages and controls a safety actuator on the firearm to which said kit is attached; and

a linkage connecting said forward trigger assembly with said trigger actuator;

wherein said trigger actuator includes a first locator plate, a second locator plate and a cam actuator positioned between said locator plates, said cam actuator including a primary trigger engagement surface.

2. The kit of claim 1 , wherein said trigger actuator further includes two locator pins extending between said first and second locator plates and said cam actuator includes an elongated slot through which said locator pins extend.

3. A bullpup conversion kit for a firearm, comprising:

a housing;

a forward trigger assembly;

a trigger actuator, wherein said trigger actuator includes a first locator plate, a second locator plate and a cam actuator positioned between said locator plates, said cam actuator including a primary trigger engagement surface; and

a linkage connecting said forward trigger assembly with said trigger actuator, wherein (1) said linkage includes a first transfer bar and a second transfer bar; (2) said cam actuator includes a first aperture and a second aperture; (3) said first locator plate includes a first elongated opening; and (4) said second locator plate includes a second elongated opening wherein a first end of said first transfer bar extends through said first elongated opening and engages in said first aperture and a second end of said second transfer bar extends through said second elongated opening and engages in said second aperture.

4. The kit of claim 3 , wherein said forward trigger assembly includes a trigger block, a trigger and a trigger pin, said trigger block including a channel that receives said trigger and allows free sliding movement of said trigger with respect to said trigger block.

5. The kit of claim 4 , wherein said trigger pin includes a third aperture and a fourth aperture, said first transfer bar including a third end engaging said third aperture and said second transfer bar including a fourth end engaging said fourth aperture.

6. The kit of claim 5 , wherein said forward trigger assembly further includes a safety trigger, a biasing spring and a projecting lug and said trigger block includes a cavity, said biasing spring biasing said lug into said cavity when said safety trigger is not engaged by an operator whereby inadvertent operation of said trigger is defeated.

7. A bullpup conversion kit for a firearm, comprising:

a housing;

a forward trigger assembly;

a trigger actuator wherein said trigger actuator includes a first locator plate, a second locator plate and a cam actuator positioned between said locator plates, said cam actuator including a primary trigger engagement surface;

a linkage connecting said forward trigger assembly with said trigger actuator; and

a slide release actuator;

and a spring, said slide release actuator being biased by said spring so as to project through an actuator opening provided in said housing.

8. The kit of claim 7 , wherein said slide release actuator includes a lug that engages a slide release on the firearm to which said kit is attached.

9. The kit of claim 7 , further including a firearm safety interlock that engages and controls a safety actuator on the firearm to which said kit is attached.

10. The kit of claim 1 , further including a recoil pad assembly including a rear adaptor block, a recoil pad support and a recoil pad.

11. The kit of claim 10 , wherein said safety interlock is carried on said recoil pad assembly.

12. The kit of claim 11 , wherein said safety interlock comprises a first resilient prong and a second resilient prong.

13. The kit of claim 12 , wherein said first prong has a first cam and said second prong has a second cam.

14. The kit of claim 13 , wherein when said recoil pad support is properly seated on the firearm, said first prong engages a safety actuator on the firearm so as to maintain the safety actuator in an off position and allow discharge of the firearm.

15. The kit of claim 14 , wherein when said recoil pad support is removed from said firearm, said second prong engages the safety actuator on the firearm so as to displace the safety actuator into an on position and thereby defeat inadvertent discharge of the firearm.

16. The kit of claim 15 , wherein said second cam is V-shaped and said second cam includes a clearance channel for the safety actuator when held by said first prong in the off position.

17. A firearm converted to a bullpup configuration; comprising:

a firearm including a receiver carrying a primary trigger and a barrel;

a conversion kit attached to said firearm, said conversion kit including a housing, a forward trigger assembly, a firearm safety interlock that engages and controls a safety actuator on the firearm to which said kit is attached, a trigger actuator and a linkage connecting said forward trigger assembly with said trigger actuator wherein said trigger actuator includes a first locator plate, a second locator plate and a cam actuator positioned between said locator plates, said cam actuator including a primary trigger engagement surface.

18. The converted firearm of claim 17 , wherein said forward trigger assembly further includes a trigger, a safety trigger, a biasing spring and a projecting lug and a trigger block having a cavity, said biasing spring biasing said lug into said cavity when said safety trigger is not engaged by an operator whereby inadvertent operation of said trigger is defeated.

19. The converted firearm of claim 17 , wherein said firearm includes a slide and a slide release and said conversion kit includes a slide release actuator that projects from an actuator opening in said housing whereby an operator may activate said slide release of said firearm.
