A universal gun cleaning kit gives you one organized case for every firearm you own, from .17 rimfire up to 12 gauge shotguns. Inside is a full set of brass cleaning rods, phosphor bronze bore brushes, jags, cotton mops, slotted tips, and patches sized for the most common calibers and gauges. Brass and bronze components stay softer than barrel steel, so they cut fouling without scoring rifling — the same reason gunsmiths have specified these materials for decades.
