US Patent:

20180094893, Apr 5, 2018

Filed:

Dec 5, 2017

Appl. No.:

15/831714

Inventors:

Chien Hwang - Salt Lake City UT, US

International Classification:

F41A 29/02

Abstract:

The present disclosure pertains to systems and methods for cleaning implements for firearms. In one embodiment, a single-use cleaning implement may include a hollow member; and a cleaning surface disposed along a length of the hollow member. The cleaning surface may be disposed about a circumference of the hollow member. A flexible shaft may be configured to extend through the hollow member. The flexible shaft may comprise a retainer component disposed at a distal end, the retainer component configured to abut a distal end of the cleaning implement and to impede the cleaning implement from passing over the retainer component. The flexible shaft may be used to pull the hollow cleaning implement through the barrel of the firearm while the retainer component abuts the distal end of the cleaning implement and the first cleaning surface engages with an inner surface of the barrel to clean the barrel.

Inventors:

Chien Hwang - Salt Lake City UT, US

International Classification:

F41A 29/02

Abstract:

The present disclosure pertains to systems and methods for cleaning implements for firearms. In one embodiment, a cleaning implement may include a distal end, a proximal end, and a shaft extending between the distal end and the proximal end, the shaft configured to be coupled to a cleaning rod. A cleaning surface may be disposed along a length of the shaft and configured to be received within a barrel of a firearm. The proximal end of the shaft may be sized to create a friction fit with the cleaning rod and the cleaning implement such that engagement between the cleaning implement and cleaning rod is maintained while the cleaning rod is pushed through the barrel from the proximal end, and the cleaning implement and the cleaning rod disengage when the cleaning rod is pulled away from the proximal end.
