Otis, the industry standard for Weapon OEM, Military, Law Enforcement Armorers & Operators.

The Otis Technology Breech-to-Muzzle® Cleaning System is widely regarded by experts as the most advanced gun cleaning system in the world. It offers many gun cleaning advancements and refinements developed for the military and competitive marksmen.

By cleaning Breech-to-Muzzle® (the direction the bullet moves through the firearm), dirt and fouling is pulled out the muzzle, not pushed back into the action gumming the trigger or causing malfunctions. Because the slotted tip with the patch is pulled through the chamber, it doesn't compress the patch against the side of the rod. Conventional rods will jam off-center, scraping the rifling in the process, and potentially ruining the bore. 

The Otis Memory-Flex® rod allows you to tightly form the patch to the bore, actually cleaning it rather than just moving the dirt around. The tight patch is formed by being pulled through the chamber, compressing in the throat, and cleans the leading edge of the rifling; the edge that actually bears the stress of the rotating bullet. For shotguns, custom soft durometer plugs, (patch savers®) force the patch to the full diameter of the bore, cleaning the chamber, forcing cone, bore and choke, all without having to disassemble the gun.
