Otis Technology FG-400 Shotgun Micro Cleaning Kit 400 makes short work of damaging residue and fouling that builds up inside your shotgun. Suitable for all bores and gauges of shotguns, from .410 bore to 10 gauge, this cleaning kit allows you to return your favorite shotgun to optimum condition without disassembling it. Use Otis Tech's patented Breech-to-Muzzle cleaning method with this Micro Cleaning Kit to pull dirt and fouling out the muzzle, not back toward the action. The Otis FG-400 All Gauge Shotgun Micro Cleaning Kit comes packaged with a variety of Otis Technology gun cleaning tools; the core component of this cleaning kit is the 36" Memory-Flex cleaning rod, which uses flexible aircraft aluminum to bend the patch to the contours of your shotgun. Besides the Memory-Flex cleaning rod, Otis Technology has also included an internal thread slotted brass tip, small and large Otis Patch Savers, a 0.5 ounce bottle of Otis O85 Ultra Bore Solvent, all caliber patches, and a 12 to 10 gauge bore brush. For a basic cleaning system that will make pristine virtually all aspects of your shotgun, use the Otis FG-400 Shotgun Micro Kit.
