Claim:
A combination barrel brush and jag, comprising: a. a set of shorter bristles having a first longitudinal length and a first transverse diameter; b. a set of longer bristles having a second longitudinal length and a second transverse diameter, the set of shorter bristles being adjacent to the set of longer bristles; and c. a stem having a first end and a second end opposite the first end, the stem defining a longitudinal axis, wherein the shorter and longer sets of bristles project radially outwardly from the stem, wherein the first transverse diameter of the set of shorter bristles is smaller than a diameter of a bore wall of a bore so as to define a gap between the bore wall and the set of shorter bristles and the second transverse diameter of the set of longer bristles is greater than the diameter of the bore wall of the bore when the brush and jag combination is concentrically positioned inside the bore, wherein the gap is approximately 0.005 inch to approximately 0.034 inch, and wherein the first longitudinal length is encompassed in approximately 5 to approximately 10 turns.
