## Abstract

An apparatus comprising a bore cleaning device operable to clean a bore of a firearm is provided. The apparatus includes a cylindrical cleaning pad including a periphery portion including a radial outer surface of the cylindrical cleaning pad, a center portion including a remainder of the cylindrical cleaning pad contained radially within the periphery portion, and a compression expansion cut disposed in the center portion and extending from a first flat end of the cylindrical cleaning pad to a center of the cylindrical cleaning pad. The apparatus further includes a propellant located in a bore-rearward position of the cylindrical cleaning pad providing a force to push the cleaning pad down the bore of the firearm and a payload located in a bore-forward position of the cylindrical cleaning pad.

## Claims

### Claim 1

An apparatus comprising a bore cleaning device operable to clean a bore of a firearm, the apparatus comprising:
a cylindrical cleaning pad including:
a periphery portion including a radial outer surface of the cylindrical cleaning pad,
a center portion including a remainder of the cylindrical cleaning pad contained radially within the periphery portion,
a plurality of parallel compression expansion cuts disposed in the center portion and extending from a first flat end of the cylindrical cleaning pad to a center of the cylindrical cleaning pad;
a propellant located in a bore-rearward position of the cylindrical cleaning pad providing a force to push the cylindrical cleaning pad down the bore of the firearm; and
a payload located in a bore-forward position of the cylindrical cleaning pad; and
wherein the cylindrical cleaning pad further includes a perpendicular compression expansion cut perpendicular to the parallel compression expansion cuts.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the plurality of parallel compression expansion cuts extend from the first flat end to a second distal flat end of the cylindrical cleaning pad.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the plurality of parallel compression expansion cuts terminate at the center of the cylindrical cleaning pad.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the plurality of parallel compression expansion cuts and the perpendicular compression expansion cut are operable to enable the cylindrical cleaning pad to expand radially when compressive forces are applied to the first flat end and a second distal flat end of the cylindrical cleaning pad.

### Claim 5

An apparatus comprising a bore cleaning device operable to clean a bore of a firearm, the apparatus comprising:
a cylindrical cleaning pad including:
a periphery portion including a radial outer surface of the cylindrical cleaning pad,
a center portion including a remainder of the cylindrical cleaning pad contained radially within the periphery portion,
a plurality of parallel compression expansion cuts disposed in the center portion and extending from a first flat end of the cylindrical cleaning pad to a center of the cylindrical cleaning pad;
a propellant located in a bore-rearward position of the cylindrical cleaning pad providing a force to push the cylindrical cleaning pad down the bore of the firearm; and
a payload located in a bore-forward position of the cylindrical cleaning pad; and
wherein the plurality of parallel compression expansion cuts are operable to enable the cylindrical cleaning pad to expand radially when compressive forces are applied to the first flat end and a second distal flat end of the cylindrical cleaning pad.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein the parallel compression expansion cuts extend from the first flat end to the second distal flat end.

### Claim 7 (depends on 5)

The apparatus of claim 5, wherein the parallel compression expansion cuts terminate at the center of the cylindrical cleaning pad.

### Claim 8 (depends on 5)

The apparatus of claim 5, wherein the cylindrical cleaning pad further includes a perpendicular compression expansion cut perpendicular to the parallel compression expansion cuts.
