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, they affix to a standard rifle rod with 8/32 thread. The .45cal Bore-tip fits standard .45 Auto as well as 45-70 Government, .460 Weatherby Mag, .480 Ruger, .455 Webley, .458 Winchester Mag and others. It can also function as a chamber brush for .22/5.56.
