Gauge and caliber specific bore-tips are tough, reusable foam tips engineered for 100% bore contact; spreading fluids more evenly than mops and patches without lint or fibers. Their non-abrasive foam allows them to be run in both directions, while their absorbency requires less solvent/lubricant. Washable and reusable, the .243 bore-tip will clean your 6mm rifles as well as your .240. They affix to a standard rod with #8-32 threading. Features: A bag contains (6) bore-tips on a runner Each tip can be used multiple time and should substantially outlast a similar priced bag of patches Washable and reusable Lint-free and fiber-free
