The Otis Technology Foaming Bore Cleaner 3oz is a bore cleaner designed for cleaning firearm barrels using expanding foam.

This Otis Technology Foaming Bore Cleaner uses an expanding foam formula that fills the bore to provide full internal coverage during cleaning. It is packaged in a 3-ounce container and is categorized as a bore cleaning solvent for firearm maintenance. In normal operation, the foam is applied from the breech and expands through the barrel before breaking down for removal. This product is used with pull-through systems or cleaning kits for residue removal. The foaming action allows consistent distribution along the bore surface, making it suitable for range use or home cleaning setups where complete coverage is required.
