Abstract

A firearm suppressor cover assembly and method of protecting a user while firing a weapon are disclosed. The cover assembly has an insulating cover assembly, a one or more clamps, one or more standoffs per clamp, and an optional heat shield. The standoffs are coupled to the one or more clamps and in contact with the insulating cover assembly thereby forming an air gap between the suppressor and the insulating cover assembly. The heat shield may be arranged within the air gap.

First claim

What is claimed is:

1. A firearm suppressor cover assembly, comprising:
one or more clamps shaped to releasably couple the firearm suppressor cover assembly to a firearm suppressor, one of the one or more clamps arranged near a rear end of the firearm suppressor cover assembly, distal from a muzzle of the firearm;
an insulating cover assembly rigidly supported to maintain an elongated shape and shaped to at least partially surround the firearm suppressor; and
two to nine standoffs extending outward from each of the one or more clamps, and in contact with the insulating cover assembly, the one or more clamps not in contact with a barrel of the firearm, the two to nine standoffs for each of the one or more clamps being circularly spaced from each other relative to a longitudinal axis of the firearm suppressor cover assembly.

2. The firearm suppressor cover assembly of claim 1 , wherein the standoffs have a length in a direction parallel to a longitudinal axis of the firearm suppressor that is less than a length of the firearm suppressor cover assembly such that circular and longitudinal convection is possible in the air gap.

3. The firearm suppressor cover assembly of claim 1 , wherein the one or more clamps include one to three clamps.

4. The firearm suppressor cover assembly of claim 3 , wherein the one or more clamps include one clamp.

5. The firearm suppressor cover assembly of claim 3 , further comprising two or three standoffs.

6. The firearm suppressor cover assembly of claim 5 , wherein the insulating cover assembly comprises an insulating cover and a rigid support having a generally cylindrical shape and being in contact with the insulating cover to support and shape the insulating cover assembly.

7. The firearm suppressor cover assembly of claim 3 , wherein the insulating cover assembly comprises an insulating cover and a rigid support having a generally cylindrical shape and being in contact with the insulating cover to support and shape the insulating cover.

8. The firearm suppressor cover assembly of claim 1 , further comprising two or three standoffs.

9. The firearm suppressor cover assembly of claim 8 , wherein the insulating cover assembly comprises an insulating cover and a rigid support having a generally cylindrical shape and being in contact with the insulating cover to support and shape the insulating cover.

10. The firearm suppressor cover assembly of claim 1 , wherein the insulating cover assembly comprises an insulating cover and a rigid support having a generally cylindrical shape and being in contact with the insulating cover to support and shape the insulating cover.

11. The firearm suppressor cover assembly of claim 1 , wherein the insulating cover assembly includes a thermally reflective liner on an inside surface configured to reflect radiative thermal energy.

12. The firearm suppressor cover assembly of claim 1 , wherein the clamps are metal.

13. The firearm suppressor cover assembly of claim 1 , further comprising at least two thermally conductive interruptions in a thermal path between the clamps and an outer surface of the cover assembly.

14. The firearm suppressor cover assembly of claim 1 , wherein the clamps have a textured or ridged inner surface configured to contact the suppressor and reduce a thermal cross section between the suppressor and the clamps.

15. The firearm suppressor cover assembly of claim 1 , wherein adjacent standoffs on the same clamp have at least 60° of circular separation as measured around the longitudinal axis of the firearm suppressor cover assembly.

16. A firearm suppressor cover assembly, comprising:
one or more clamps shaped to releasably couple the firearm suppressor cover assembly to a firearm suppressor, one of the one or more clamps arranged near a rear end of the firearm suppressor cover assembly, distal from a muzzle of the firearm;
an insulating cover assembly rigidly supported to maintain an elongated shape and shaped to at least partially surround the firearm suppressor; and
two to nine standoffs extending outward from each of the one or more clamps, and in contact with the insulating cover assembly to form an air gap between the one or more clamps and the insulating cover assembly, the two to nine standoffs being circularly spaced from each other relative to a longitudinal axis of the firearm suppressor cover assembly.
