The Otis Range Box is the universal cleaning solution that lives in the range bag — a comprehensive kit covering pistols, rifles, and shotguns from a single rugged carry box. Otis’s Memory-Flex cable lets the cleaning line pull a brush or patch through the bore from breech to muzzle, the way professional armorers clean firearms.
The kit includes bore brushes for every standard caliber, patches, solvent, lubricant, and the obstruction-removal tools needed for trail-side jams. Hard-sided box keeps everything organized through range trips, hunting weekends, and military deployments — same kit design used by US Army, Navy, and Marine units.
Otis Technology has been making gun cleaning systems in Lyons Falls, New York since 1985. Every Otis kit is hand-assembled in their Adirondack-foothills facility, using the same Memory-Flex cable design that’s been the standard for US military firearm maintenance for decades. Made in the USA.
