Firearm configuration for reducing recoil

1. A firearm configuration ( 10 ) for reducing recoil forces encountered by a user of a firearm ( 12 ), the firearm configuration ( 10 ) being triggered by the user's trigger finger, the firearm configuration comprising:

an upper housing ( 14 ), the upper housing including a barrel ( 16 ) and a firing assembly ( 18 ) arranged along a first axis ( 24 ), the upper housing ( 14 ) having a recoil mass ( 22 ) with an opening, a lower section ( 46 ), and an upper section ( 48 ), wherein the recoil mass ( 22 ) includes a heavier lower section ( 46 ) as compared to the upper section ( 48 );

a lower housing ( 26 ) slidably interconnected to the upper housing ( 14 ), a trigger ( 28 ) and trigger assembly ( 32 ) positioned within the lower housing ( 26 ), the trigger assembly ( 32 ) being interconnected to the firing assembly ( 18 ), the trigger assembly ( 32 ) being used to selectively actuate the firing assembly ( 18 ) and fire the firearm ( 12 ), the lower housing ( 26 ) further including a guide rod ( 42 ) and recoil spring ( 44 ) extending through the opening in the recoil mass ( 22 ) and arranged upon a third axis ( 46 ) below and parallel to the first axis ( 24 ), the recoil mass ( 22 ) adapted for linear movement along the guide rod ( 42 ) continuously parallel to the first axis ( 24 ) and in alignment with the trigger ( 28 ); and

a recoil plate ( 52 ) formed forwardly of the trigger assembly ( 32 ), the recoil plate ( 52 ) absorbing forces generated by the recoil mass ( 22 ) during firing;

wherein after firing the firearm ( 12 ), the upper housing ( 14 ) and the recoil mass ( 22 ) slide back with respect to the lower housing ( 26 ) with the recoil mass ( 22 ) sliding along the guide rod ( 42 ) to thereby compress the recoil spring ( 44 ), and wherein the recoil of the firearm ( 12 ) is reduced by positioning the recoil mass ( 22 ) substantially in line with the user's trigger finger or arm.

2. The firearm configuration ( 10 ) as described in claim 1 further comprising a magazine ( 36 ) with ammunition ( 38 ), the ammunition ( 38 ) being delivered upwardly into the upper housing ( 14 ) between the barrel ( 16 ) and the firing assembly ( 18 ).

3. The firearm configuration ( 10 ) as described in claim 1 wherein a first axis ( 24 ) extends along the barrel ( 16 ), the trigger ( 28 ) pivots about a second axis ( 34 ), a third axis ( 46 ) extends along the guide rod ( 42 ) and wherein the third axis ( 46 ) is located substantially below the first axis ( 24 ) and the second axis ( 34 ).

4. The firearm configuration ( 10 ) as described in claim 1 wherein the upper housing ( 14 ) or substantial portion thereof is made of a light weight material comprising aluminum, titanium, carbon fiber composite or a similarly light weight polymer.

5. The firearm configuration ( 10 ) as described in claim 1 wherein the lower section ( 46 ) of recoil mass ( 22 ) is made of tungsten.

6. The firearm configuration ( 10 ) as described in claim 1 wherein the lower section ( 46 ) of recoil mass ( 22 ) is made of bismuth.

7. The firearm configuration ( 10 ) as described in claim 1 wherein the lower section ( 46 ) of recoil mass ( 22 ) is made of depleted uranium.

8. A firearm configuration for reducing recoil forces encountered by the user of a firearm, the firearm having forward and rearward extents, the firearm configuration comprising:

an upper housing, the upper housing including a barrel arranged along a first axis, the upper housing having a recoil mass comprising a weighted lower section and a non-weighted upper section with a central opening, the upper housing and recoil mass sliding to the rearward extent of the firearm upon firing;

a lower housing slidably interconnected to the upper housing, a trigger and trigger assembly positioned within the lower housing, the trigger assembly being used to fire the firearm, the lower housing further including a guide rod and recoil spring interconnected to the recoil mass and arranged upon a third axis below and parallel to the first axis and in alignment with the trigger; and

a recoil plate position forward of the trigger;

wherein the recoil mass is used to reduce recoil forces upon firing.

9. The firearm configuration as described in claim 8 wherein the recoil mass is adapted for linear movement along the guide rod continuously parallel to the first axis.

10. The firearm configuration as described in claim 8 wherein the firearm has a center of mass and wherein the recoil mass moves along an axis that passes through the center of mass.

11. The firearm configuration as described in claim 8 further comprising a firing assembly arranged along the first axis, the trigger assembly being interconnected to the firing assembly and being used to selectively actuate the firing assembly.

12. The firearm configuration as described in claim 8 wherein the recoil mass includes an opening and wherein the guide rod extends fully through the opening in the recoil mass.

13. The firearm configuration as described in claim 12 wherein there is a step formed within the opening of the recoil mass and wherein the recoil spring is positioned upon the step.

14. The firearm configuration as described in claim 8 wherein one of the surfaces of the recoil mass is sloped.

15. The firearm configuration ( 10 ) as described in claim 8 wherein the upper housing ( 14 ) or a substantial portion thereof is made of a light weight material comprising aluminum, titanium, carbon fiber composite or a similarly light weight polymer.

16. The firearm configuration ( 10 ) as described in claim 8 wherein the lower section ( 46 ) of recoil mass ( 22 ) is made of tungsten.

17. The firearm configuration ( 10 ) as described in claim 8 wherein the lower section ( 46 ) of recoil mass ( 22 ) is made of bismuth.
