Pro-Shot Pro-Clean Gun Cleaner

Pro-Clean is Pro-Shot's gun cleaner, the bottle that comes out at the start of a cleaning session before any oil goes near the gun. Wet a patch, push it through the bore, let it sit while you work on the action, then follow with a brush and dry patches until they come out clean.

It does the same job on a bolt face, a carrier or the underside of a slide: wet a utility brush, scrub, wipe off what comes loose. Treat it like any solvent and keep it off wood and finished stocks.
