Firearm vise block

1. A firearm vise block, comprising:

a block body, the block body having:

a first side structured and configured to be clamped between jaws of a bench vise;

a second side structured and configured to fit within an ammunition magazine well of a firearm, the second side being adjustable between at least an insertion state and an expanded state;

at least two contacting portions expandable outward along a first axis;

at least two additional contacting portions expandable outward along a substantially different second axis, and

an adjustment mechanism selectively and reversibly expands both the at least two contacting portions outward along the first axis and the at least two additional contacting portions outward along the substantially different second axis thereby causing the second side of the block body to move from the insertion state to the expanded state.

2. The block of claim 1 , wherein the first side and the second side are on substantially opposing ends of the block body.

3. The block of claim 1 , wherein:

in the insertion state, the second side is readily slideably insertable into the ammunition magazine well; and

when in the expanded state, one or more contacting portions of the second side are disposed further away from a central axis of the second side, relative to when in the insertion state, such that when the second side is inside the ammunition magazine well when in the expanded state, the contacting portions contact interior surfaces of the ammunition magazine well sufficient to secure the block body to the ammunition magazine well.

4. The block of claim 3 , wherein the adjustment mechanism is structured and configured to reversibly move the second side of the block body between the insertion state and a plurality of expanded states, wherein among the plurality of expanded states, the one or more contacting portions are disposed further away from the central axis of the second side by varying degrees, such that the plurality of expanded states accommodate varying dimensions of ammunition magazine wells.

5. The block of claim 3 , wherein when the block body and the ammunition magazine well are mutually secured with the second side of the block body in the expanded state, they are so secured essentially without perceptible free play.

6. The block of claim 3 , wherein:

the block body is substantially formed of a single piece of a resilient material; and

the one or more contacting portions are cantilevered away from a central portion of the body block.

7. The block of claim 6 , wherein the adjustment mechanism includes a wedge selectively movable via human manipulation that moves the second side between the insertion state and the expanded state.

8. The block of claim 7 ,

wherein the adjustment mechanism further includes:

a threaded post rotatably secured to the block body; and

an adjustment handle coupled to the threaded post such that human manipulation of the adjustment handle is readily translated into rotation of the threaded post; and

wherein the wedge is tapped with threads complementary to the threaded post such that rotation of the threaded post is transformed into translation of the wedge.

9. The block of claim 8 , wherein the adjustment mechanism is structured and configured such that the wedge is reversibly moveable between an insertion state position and an expansion state position by human manipulation of the adjustment handle, and via the threaded post, wherein when in the expanded state position, the wedge forces the one or more contacting portions further away from the central axis of the second side, relative to when in the insertion state position.

10. The block of claim 6 , wherein the one or more contacting portions include a first pair of contacting portions that, when in the expanded state, are disposed further away from each other, relative to when in the insertion state.

11. The block of claim 10 , wherein the one or more contacting portions further include a second pair of contacting portions that, when in the expanded state, are disposed further away from each other, relative to when in the insertion state.

12. The block of claim 1 , wherein the second side of the block body includes a magazine lock notch structured and configured to cooperate with a magazine lock mechanism of the firearm.

13. The block of claim 1 , wherein the adjustment mechanism is structured and configured to selectively and reversibly move the second side between the insertion state and the expanded state via human manipulation.

14. The block of claim 1 , wherein the adjustment mechanism is structured and configured to selectively and reversibly move the second side between the insertion state and the expanded state under power provided by a motor.
