Otis AR-15 Chamber Brush & Mop Set 8-32 Threads

The Otis AR-15 Chamber Brush & Mop Set is a purpose-built cleaning kit for MSR/AR-platform rifles chambered in 5.56 NATO / .223 Rem. Designed around the notoriously hard-to-reach AR-15 star chamber, this set gives you the brushes and mops needed to keep the chamber, lugs, and bore free of carbon and fouling after a day at the range.

All components feature standard 8-32 threads, so they interchange with the rest of your Otis cleaning gear and accept other 8-32 accessories on your cleaning rod or handle. The set includes a dedicated 5.56 NATO / .223 Rem bore brush for scrubbing the bore, a purpose-built chamber brush for cutting carbon out of the star chamber, and a chamber mop for applying solvent and wiping the chamber clean.

Compact, affordable, and purpose-built for the AR-15, this brush and mop set is an essential addition to any MSR owner's range bag or cleaning bench.
