KleenBore MOP9 Cotton Bore Mop .38/.357/9mm 8-32 Thread

The KleenBore MOP9 delivers thorough bore cleaning for .38 Special, .357 Magnum, and 9mm handguns with its 100% cotton construction that absorbs solvents and removes fouling effectively. This bore mop features the standard 8-32 thread pattern for universal compatibility with most cleaning rod systems.

What Makes This Different

Unlike synthetic cleaning patches that can leave residue, the MOP9 uses pure cotton fibers that naturally absorb cleaning solvents and carbon buildup without scratching bore surfaces. The twisted cotton construction creates multiple contact points along the bore length, ensuring complete coverage from chamber to muzzle. Standard 8-32 threading eliminates compatibility issues with major cleaning rod manufacturers.

Key Features

• 100% cotton construction absorbs maximum solvent volume
• 8-32 thread pattern fits Dewey, Pro-Shot, and most cleaning rods
• Caliber-specific sizing for .38 Special, .357 Magnum, and 9mm
• Twisted fiber design maximizes bore contact surface
• Non-abrasive material protects rifling and bore finish

The MOP9 excels in competition environments where consistent accuracy demands pristine bore conditions. Law enforcement armorers rely on cotton mops for final cleaning steps before weapon inspection. The natural cotton fibers conform to bore irregularities and rifling grooves that rigid brushes might miss, making this mop particularly effective for removing stubborn lead deposits from cast bullet shooting.
