Otis 37mm/40mm/12 ga Less Lethal Cleaning Kit

The Otis 37mm/40mm/12 Gauge Less Lethal Cleaning Kit provides a complete maintenance solution for less lethal launcher systems and shotguns. This specialized cleaning system is engineered with breech-to-muzzle methodology, utilizing Otis's Memory-Flex cables and purpose-designed components to maintain consistent bore condition and operational reliability across multiple platform types.

The kit includes oversized bore brushes sized specifically for 37mm and 40mm grenade launchers, 100% cotton 4-inch patches rated for thorough debris removal, and brass brush components that prevent bore damage during extended cleaning cycles. These materials address the unique cleaning demands of less lethal platforms, where residue buildup from practice rounds or field deployment can affect shot-to-shot consistency and launcher function. The Memory-Flex cable system provides flexibility for navigating the internal geometry of launcher chambers without kinking or binding.

Users maintaining 37mm or 40mm less lethal systems, 12-gauge training shotguns, or multi-role launcher platforms benefit from having dedicated cleaning components sized to each bore. Agencies, training facilities, and tactical teams conducting regular qualification or qualification-adjacent training on these systems rely on consistent bore maintenance to ensure reliability during deployed operations. The kit consolidates multiple bore diameters into a single carrying case, reducing inventory management for units maintaining mixed launcher inventories.

Otis Products has built its reputation on precision cleaning systems designed for duty weapons and specialty platforms. This less lethal kit applies the same engineering approach—proper cable design, material selection, and bore-matched components—that defines their rifle and pistol system offerings, adapted for the distinct maintenance profile of less lethal delivery systems.
