OTIS MC#7 Bore Cleaner & Conditioner 1 Gallon SHF-MC7128

Shooter's Choice MC#7 Bore Cleaner & Conditioner by Otis Technology provides high-volume users, armorers, and gunsmiths with a concentrated, one-step bore cleaning solvent. The premium solution chemically targets and dissolves aggressive carbon buildup, lead, copper, powder fouling, and plastic shotgun wad residue. It cleans non-abrasively to protect the rifling and crown structure from friction degradation or damage. As it strips away performance-robbing contaminants, the formula seasons the barrel interior to reduce future fouling buildup and shield steel from atmospheric corrosion. This bulk one-gallon container is ideal for high-capacity shop use, supply replenishment, or deep-soaking armorer basins.
