Super Brush Bore Tips Swab-Its By Superbrush.
Reusable Foam Swabs For Precision Cleaning
Bore Tips are a convenient, all-in-one replacement for traditional jags and patches. They feature plastic adapters that fit 8-32 female threads commonly found on cleaning rods, and are reusable up to five times. Bore Tips tightly fit the bore for thorough cleaning, and the spongy foam absorbs solvents and oils for uniform application. Stands up to most cleaning chemicals. Note: .45 caliber Bore Tips will not fit .44 caliber barrels. Pair up with J-B Bore Cleaning Compound for a very easy clean.
