Your 20 gauge bore brush scrubs the fouling - this cotton bore mop absorbs it and carries it out of the barrel. The densely packed 100% cotton head absorbs solvent and trapped residue in a single pass, leaving your 20-gauge bore clean and ready for a light coat of oil.

The 20 gauge's smaller bore (0.615") means a gun cleaning mop sized precisely for it matters. An oversized mop drags and bunches; an undersized one skips over residue. This bore mop fits the 20 GA bore snugly, so the cotton makes full contact with the bore walls and picks up every bit of loosened carbon and plastic wad fouling.

Use it two ways: wet with solvent after brushing for bore cleaning, then dry or lightly oiled for protection. Wash and reuse until the cotton wears thin. This shotgun cleaning mop finishes what the brush started - quick, effective, done.

Does a 20 gauge bore mop fit a 16 gauge barrel?

No. A 20 gauge bore is 0.615 inches, while a 16 gauge is 0.663 inches - the mop would be too small to make proper contact with a 16 gauge bore. Bore mops need to fit snugly to absorb fouling effectively. Using the wrong size means solvent runs past instead of soaking into the barrel walls.

What is the difference between a bore mop and cleaning patches?

A mop is a cylindrical bundle of cotton that contacts the entire bore surface at once, holding more solvent than a flat patch. Patches are flat squares wrapped around a jag - they give better visual feedback (you can see how dirty the patch is) but carry less solvent per pass. For a 20 gauge, the mop is faster for applying solvent and the first few cleanup passes, while patches are better for the final inspection.

How do I clean a cotton bore mop after use?

Rinse it in hot water with dish soap, or soak it in bore solvent for a few minutes and squeeze out the residue. Let it air dry completely before storing. Never store a damp mop - trapped moisture can corrode the threaded stem and promote rust inside your cleaning kit. When the cotton starts to fray or shed fibers, replace the mop.

Can I use any solvent with a cotton bore mop?

Cotton is compatible with virtually all gun cleaning solvents, including CLP, bore cleaners, and copper solvents. Unlike bronze bore brushes, cotton does not react with copper-specific solvents — so patches and mops give you a true color reading when checking for copper fouling. This makes the mop a better solvent applicator than a bronze brush.

Do I need both a bore mop and a bore brush for my 20 gauge?

Yes - they do different jobs. The bore brush physically scrubs fouling off the barrel walls. The mop absorbs the loosened fouling and solvent. Skipping the brush means the mop pushes residue around without breaking it free. Skipping the mop means loosened fouling stays in the bore. Together, they make cleaning faster and more thorough than either alone.
