WOOL BORE MOPS by BROWNELLS are designed to hold a generous amount of bore cleaner or oil for effective barrel coating.
The natural wool construction provides flexibility to conform to rifling grooves without scratching the bore, thanks to its looped and twisted brass shank and coupling.
These mops are suitable for .50 caliber rifles and handguns, with a 3ΒΌ" (8.3cm) length and 8-32 thread, except for .17 cal. which has a 5-40 thread.
