Mission Critical, by Otis Technologies, pairs a 1-oz. spray bottle of the company’s MC-10 Cleaner with a 1-oz. spray bottle of its MC-10 Lubricant for a firearm maintenance system that can withstand temperatures ranging from -65° F to 650° F without freezing, gumming up or burning off. Intended for use anywhere there’s metal-to-metal contact, the cleaner removes carbon, fouling and other residue, and prepares the surface for the synthetic lubricant, which penetrates the metal to provide long-lasting protection and lubricity. Mission Critical is safe for use on all metals and finishes, and comes with a microfiber cleaning cloth. Price: $30. Contact: Otis Technologies; (800) 684-7486; otistec.com.
