Firearm bore cleaning jag

Abstract

A firearm bore cleaning jag includes an elongated body defining an axis, with a first set of multiple fins and a second set of multiple fins positioned at first and second positions, respectively along the length of the body. Each of the fins has two opposed surfaces. Each of the opposed surfaces has an angle characteristic measured with respect to the axis. The opposed surfaces of each fin have different angle characteristics, such that one of the opposed surfaces is less acute than the other. The first set of multiple fins is arranged with their less acute surfaces facing in a first direction, and the second set of multiple fins are arranged with their less acute surfaces facing in a second direction opposite the first direction.

1 . A firearm bore cleaning jag comprising:
 an elongated body defining an axis;   a first set of multiple fins at a first position along the length of the body;   a second set of multiple fins at a second position along the length of the body;   wherein each fin has two opposed surfaces;   wherein each of the opposed surfaces has an angle characteristic measured with respect to the axis;   wherein the opposed surfaces of each fin have different angle characteristics, such that one of the opposed surfaces is less acute than the other;   wherein the first set of multiple fins is arranged with their less acute surfaces facing in a first direction; and   wherein the second set of multiple fins is arranged with their less acute surfaces facing in a second direction opposite the first direction.   
     
     
         2 . The cleaning jag of  claim 1 , wherein one of the opposed surfaces of each fin is perpendicular to the body axis. 
     
     
         3 . The cleaning jag of  claim 1 , further comprising two first sets of multiple fins and two second sets of multiple fins. 
     
     
         4 . The cleaning jag of  claim 3 , further comprising:
 wherein the two first sets of multiple fins have an intervening second set of multiple fins; and   wherein the two second sets of multiple fins have an intervening first set of multiple fins.   
     
     
         5 . The cleaning jag of  claim 1 , further comprising:
 at least two first sets of multiple fins and at least two second sets of multiple fins;   wherein the first sets of multiple fins alternate with the second sets of multiple fins along the length of the body.   
     
     
         6 . The cleaning jag of  claim 1 , wherein the difference between the angle characteristic of the less acute opposed surface and the angle characteristic of the more acute opposed surface is always positive. 
     
     
         7 . The cleaning jag of  claim 1 , wherein the angle characteristics of the opposed surfaces differ by at least 20°. 
     
     
         8 . The cleaning jag of  claim 1 , wherein the angle characteristics of the opposed surfaces differ by an amount in the range of 20° to 90°. 
     
     
         9 . The cleaning jag of  claim 1 , wherein the opposed surfaces of each fin meet to define a rim having a width. 
     
     
         10 . The cleaning jag of  claim 9 , wherein the rim width ranges from 0 inches to 0.042 inches. 
     
     
         11 . The cleaning jag of  claim 1 , wherein each fin is a surface of revolution defined by the axis. 
     
     
         12 . The cleaning jag of  claim 11 , wherein the first set of multiple fins is separated from the second set of multiple fins by a neck portion of the body having a diameter that is less than the diameter of a fin. 
     
     
         13 . The cleaning jag of  claim 1 , further comprising a connector attached to the body, wherein the connector is adapted for connection to a cleaning rod. 
     
     
         14 . A firearm bore cleaning jag comprising:
 an elongated body defining an axis;   a first set of multiple fins at a first position along the length of the body;   a second set of multiple fins at a second position along the length of the body;   wherein each fin has two opposed surfaces;   wherein each of the opposed surfaces has an angle characteristic measured with respect to the axis; and   wherein the opposed surfaces of each fin have different angle characteristics, such that one of the opposed surfaces is less acute than the other.   
     
     
         15 . The cleaning jag of  claim 14 , further comprising a connector attached to the body, wherein the connector is adapted for connection to a cleaning rod. 
     
     
         16 . The cleaning jag of  claim 14 , wherein the difference between the angle characteristic of the less acute opposed surface and the angle characteristic of the more acute opposed surface is always positive. 
     
     
         17 . The cleaning jag of  claim 14 , wherein the angle characteristics of the opposed surfaces differ by at least 20°. 
     
     
         18 . The cleaning jag of  claim 14 , wherein the angle characteristics of the opposed surfaces range from 20° to 90°.
