The Otis Technology Defender Series Cleaning Kit is a complete multi-caliber gun-cleaning system built around the brand’s patented Breech-to-Muzzle cleaning technique — pulling the cable through the bore in the same direction the bullet travels, preventing fouling from being pushed back into the action.
The kit includes Memory-Flex cleaning cables (replacing rigid rods that risk damaging the bore), bronze and nylon brushes, cleaning patches, and the brand’s FP-10 lubricant. Compact zippered case fits in a range bag or vehicle compartment.
Otis Technology has manufactured gun cleaning kits in Lyons Falls, New York since 1985 — the standard cleaning kit issued to US military and federal law enforcement agencies.
