Brownells Ar-15/M16 Cotton Chamber Mop 223 Remongton 12 Pack

Proper chamber cleaning is non-negotiable for reliable AR-15 and M16 function, and the Brownells AR-15/M16 Cotton Chamber Mop in .223 Remington is purpose-built to do the job efficiently. This 12-pack of cotton mops tackles one of the hardest-to-reach areas on your rifle—the chamber and locking lug recesses—with a clever two-part design that eliminates the need to swap tools mid-cleaning.

Each mop features a long, thin section loaded with individually-tied cotton strands that snakes through the chamber with precision, working like thousands of tiny fingers to lift fouling, carbon, and debris. The opposite end switches gears: a short, larger-diameter section is sized specifically to clean and lubricate the locking lug recesses where carbon loves to hide. This dual-purpose approach saves time and keeps your rifle cleaner than conventional patches alone.

The cotton construction works wet or dry—pair it with your favorite solvent for aggressive fouling removal, or run it dry to distribute light lubricant after solvent cleaning. With a 12-pack on hand, you'll have spares for follow-up cleanings without hunting for replacements. Whether you're maintaining a range gun, hunting rifle, or tactical build, these mops are a smart shortcut to thorough chamber maintenance on the AR platform.
