Shooters Choice MC#7 Extra Strength Bore Foam 12 oz Aerosol Can

The Shooters Choice MC#7 Extra Strength Bore Foam is a one-step concentrated aerosol bore cleaner formulated to quickly strip copper, lead, carbon, and powder fouling from firearm bores. Packaged in a 12 oz aerosol can, the foam clings inside the bore for extended contact time and breaks down fouling faster and more effectively than the original MC#7 formula.

MC#7 is ammonia-free and non-abrasive, making it safe for barrel steel and bore finishes. Beyond the bore itself, the foam can also be used on receivers and trigger groups, giving shooters a single product for complete firearm maintenance. It works equally well on handguns, rifles, and shotguns, removing both carbon and copper fouling in one application.

Spray a generous coat of foam into the bore, allow it to dwell and break down fouling, then follow with a patch and your standard bore cleaning routine.
