Boresmith TM Triangle Patches TM

500 premium cleaning patches in a poly bag with an info card. Make your firearm Cleaner Faster TM.

Longer Sides and Notches

These rifle/pistol cleaning patches have a side length of 3.8 inches, and that is much longer than the side of a typical 2.5-inch square patch. The longer side means a longer radius, and a longer radius means Triangle Patches TM reach farther down a jag. Reaching farther down a jag means more bore contact. They work best when used with long jags or our Jag Brushes TM. See jag selection.

Notches at the middle of the sides prevent our patch from getting stuck inside the bore.
