The Otis MPSR Cleaning Kit (brand part no. FG556MPSR) is packed specifically to clean and maintain piston-driven AR and modern sporting rifles chambered in 5.56 NATO or .223 caliber. Otis Technologies, made in Lyons Falls, NY, fits everything the kit needs into a lightweight, compact soft pack case, keeping the gear organized and ready to grab for a range day or a field cleaning session. Owners of gas-piston AR-platform rifles get a kit tailored to that operating system rather than a generic direct-impingement cleaning kit that misses piston-specific needs.
