Latched charging handle with mechanical advantage separator

1. A charging handle for a firearm comprising:

a charging handle base having a first end and a second end;

the first end arranged for positioning within a first part of the firearm;

the second end having a charging handle latch pivotably attached thereto, the charging handle latch arranged to engage a second part of the firearm to retain the second end in position; and

a pivoting charging handle removal lever coupled to the charging handle base, the pivoting charging handle removal lever having three separate locations to achieve a mechanical advantage:

(a) a first location which engages the charging handle base or the charging handle latch,

(b) a second location which engages a third part of the firearm different than the first part of the firearm and the second part of the firearm, and

(c) a third location exposed for application of manual force and positioned to achieve a mechanical advantage for releasing the charging handle when stuck in the firearm.

2. The charging handle of claim 1 , wherein the first location is positioned in an area between the second location and the third location.

3. The charging handle of claim 1 , wherein the pivoting charging handle removal lever disengages the charging handle latch from the firearm when actuated.

4. The charging handle of claim 3 , wherein the pivoting charging handle includes a cam-lug that rotates the charging handle latch away from the charging handle base during rotation of the pivoting charging handle removal lever.

5. The charging handle of claim 1 , wherein the pivoting charging handle removal lever includes a handle portion extending from the first location to the third location and a load portion extending from the first location to the second location; and

wherein the handle portion is selectively pivotable relative to the load portion so as to configure the pivoting charging handle removal lever from stored configuration to a deployed configuration.

6. The charging handle of claim 5 , wherein the handle portion is coupled to the load portion by a spline shaft having splines; and

wherein the handle portion and load portion each have spline openings having one or more teeth and gaps sized to engage the spline shaft.

7. The charging handle of claim 6 , wherein the spline shaft, the handle portion, and the load portion are arranged such that the spline shaft rotationally couples the handle portion and the load portion in one or two configurations.

8. The charging handle of claim 7 , wherein the spline shaft has a first circumferential portion that, when positioned within the spline opening of the load portion, rotationally locks the spline shaft relative to the load portion; and

wherein the spline shaft has a second circumferential portion that, when positioned within the spline opening of the load portion, allows at least 50 degrees of rotation of the load portion relative to the spline shaft.

9. The charging handle of claim 1 , wherein the charging handle is for an AR style firearm.

10. The charging handle of claim 9 , wherein:

the first end of the charging handle base defines an opening arranged to receive a portion of a bolt carrier group of the firearm.

11. A charging handle for a firearm comprising:

a charging handle base having a first end and a second end;

the first end arranged for positioning within a housing of the firearm;

the second end having a charging handle latch pivotably attached thereto, the charging handle latch arranged to engage the firearm to retain the second end in fixed position relative to the housing; and

a rearward-assist member arranged to provide a mechanical advantage upon application of a force to move the second end of the charging handle base away from the housing when the charging handle latch is disengaged from the firearm;

wherein the rearward-assist member is arranged to apply a force against the firearm over a range of movement of the second end away from the housing.

12. The charging handle of claim 11 , wherein:

when the rearward-assist member disengages the charging handle latch from the housing when actuated.

13. The charging handle of claim 11 , wherein:

the rearward-assist member is a simple machine.

14. The charging handle of claim 13 , wherein:

the simple machine is a lever pivotably coupled to the charging handle base, the lever having three separate locations to achieve a mechanical advantage:

(a) a first location pivotably coupled to the charging handle base,

(b) a second location which engages the firearm, and

(c) a third location comprising a handle for contact with a user's hand.

15. The charging handle of claim 14 , wherein the first location is positioned in an area between the second location and the third location.

16. The charging handle of claim 14 , wherein the lever includes a cam-lug that rotates the charging handle latch away from the charging handle base during rotation of the lever.

17. The charging handle of claim 15 , wherein the lever includes a handle portion extending from the first location to the third location and a load portion extending from the first location to the second location; and

wherein the handle portion is selectively pivotable relative to the load portion so as to configure the lever from stored configuration to a deployed configuration.

18. The charging handle of claim 17 , wherein the handle portion is coupled to the load portion by a spline shaft having splines; and

wherein the handle portion and load portion each have spline openings having one or more teeth and gaps sized to engage the spline shaft.

19. The charging handle of claim 11 , wherein the charging handle is for an AR style firearm.

20. The charging handle of claim 19 , wherein:

the first end of the charging handle base defines an opening arranged to receive a portion of a bolt carrier group of the firearm.
