Rubber panel attachable to a rail system of a firearm

1. A rubber panel attachable to keyholes of a rail system of a firearm, the rubber panel comprising:

an elongated body comprising a first side, a second side, an upper edge, a lower edge, a first end, and a second end;

a gripping surface disposed on the first side of the elongated body; and

a plurality of attachment protrusions disposed on the second side of the elongated body, with each attachment protrusion comprising a first portion having a lesser width dimension in plan view and a second portion having a greater width dimension in plan view, the first and second portions being upwardly extending and disposed around the entire perimeter of a respective attachment protrusion for mating engagement with the rail system of the firearm;

the first and second portions having inwardly deformable inner and outer surfaces, and having inwardly tapered guide surfaces disposed on the outer surfaces thereof, thereby to guide the respective attachment protrusion into a respective keyhole and to facilitate insertion and attachment of the respective attachment protrusion to the rail system; and

the first portion of the respective attachment protrusion having a securement lip unitarily formed with the inwardly tapered guide surfaces and laterally extending from the first portion of the respective attachment protrusion for mating and gripping engagement with the respective keyhole of the rail system upon insertion of the respective attachment protrusion thereinto.

2. The rubber panel of claim 1 , wherein the first portion and the second portion of each attachment protrusions collectively form a substantially keyhole-shaped protrusion which comprise a rounded portion connected to a substantially rectangular portion.

3. The rubber panel of claim 1 , wherein the first portion of each attachment protrusion is substantially rectangular and the second portion of each attachment protrusion is substantially circular.

4. The rubber panel of claim 1 , wherein the first portion of each attachment protrusion comprises a substantially hexagonal cross-section.

5. The rubber panel of claim 1 , wherein the securement lip of the first portion of each attachment protrusion is continuous.

6. The rubber panel of claim 1 , wherein the upper edge of the elongated body comprises an upper curved lip.

7. The rubber panel of claim 1 , wherein the lower edge of the elongated body comprises a lower curved lip.

8. The rubber panel of claim 1 , wherein the first end of the elongated body is rounded.

9. The rubber panel of claim 1 , wherein the second end of the elongated body is rounded.

10. The rubber panel of claim 1 , wherein the first portion of each attachment protrusion has sides that are substantially parallel in plan view for mating engagement with the keyholes of a rail system and extends from the second portion of each attachment protrusions.

11. The rubber panel of claim 1 wherein each attachment protrusion has a hollow central portion.

12. A rubber panel attachable to rectangular holes of a rail system of a firearm, the rectangular holes having rounded corners for attachment of accessory mounting rails or mounts or accessories, the rubber panel comprising:

an elongated body comprising a first side, a second side, an upper edge, a lower edge, a first end, and a second end;

a gripping surface disposed on the first side of the elongated body;

a plurality of rectangular attachment protrusions with rounded corners disposed on the second side of the elongated body, with each attachment protrusion comprising a rectangular portion having a rectangular dimension in plan view, the rectangular portion being upwardly extending and disposed around the entire perimeter of a respective attachment protrusion for mating engagement with the rail system of the firearm; and

the rectangular portion having inwardly deformable inner and outer surfaces, and having inwardly tapered guide surfaces disposed on the outer surfaces thereof, thereby to guide the respective attachment protrusion into a respective rectangular hole and to facilitate insertion and attachment of the respective attachment protrusion to the rail system; and

the rectangular portion having a continuous securement lip unitarily formed with the inwardly tapered guide surfaces and laterally extending from the rectangular portion of the respective attachment protrusion and disposed about the entire perimeter of the respective attachment protrusion for mating and engagement with the respective rectangular hole of the rail system upon insertion of the respective attachment protrusion thereinto.
