This .44 / .45 Cal bore mop is designed to help maintain clean barrels for improved shooting accuracy by gently removing excess powder, buildup, and debris while preserving firearm integrity. Made from 100% soft, washable, and reusable cotton, it provides an effective cleaning solution without scratching or damaging the rifling. Equipped with external brass threading and a standard #8-32 thread, it allows for easy attachment to cleaning rods. The mop is engineered to achieve a consistent compression fit against the bore wall, helping it reach into the lands and grooves to effectively lift carbon deposits. Compact and convenient, it can be stored in a range bag or cleaning kit alongside other firearm maintenance tools, brushes, and solvents for reliable and versatile use.
