Pro-Shot Mopster Long Cotton Mop 12 ga (5/16-27 Thread) - 10" Length

The Pro-Shot Mopster Long Cotton Mop 12 ga (5/16-27 Thread) is a purpose-built bore cleaning and lubrication tool engineered for shooters and armorers who demand consistent, reliable maintenance of their shotguns. This 10-inch working length mop fits standard 12-gauge bore dimensions and threads directly onto compatible cleaning rod systems via the 5/16-27 thread pattern. Whether you're maintaining duty weapons, hunting shotguns, or competition firearms, this cotton mop delivers the controlled cleaning action necessary for proper barrel care between rounds and after shooting sessions.

Constructed from 100 percent cotton with a brass core, the Pro-Shot Mopster generates superior foaming action when paired with bore oils and solvents—a critical feature that maximizes lubrication penetration and breakdown of carbon fouling. The brass core resists corrosion and provides structural integrity during the vigorous scrubbing motions required for effective bore maintenance. The cotton fibers are tightly wound to maintain their shape and absorbency across multiple cleaning cycles, ensuring the mop doesn't shed fibers that could contaminate the bore or interfere with subsequent accuracy. At 0.15 lbs and compact in profile, it integrates seamlessly into any maintenance kit without adding bulk.

Law enforcement armorers, military small-arms custodians, and civilian shooters benefit most from this mop's reliability and ease of use. The 5/16-27 thread pattern is the industry standard for 12-gauge cleaning rods, making compatibility straightforward across major rod manufacturers. Simply attach to your cleaning rod, apply bore solvent or light machine oil, and work the mop back and forth through the barrel to remove fouling and establish a protective lubricant film. For best results, follow with a dry patch to remove excess oil before returning the firearm to service.
