I recently got to check one of these and it is wicked. The Small Arms Armorer’s Tool Case is stocked with everything you need to service standard US military issue weapons (M9, M4, M16, M240B, M249SAW, Mk19, etc.). It includes a full complement of Armorer’s Tools, (Roll Pin Punches, Hammers, and Twisting Pliers) as well as Otis’s Quick Detach Armorer’s Tool Bag and the Otis Deluxe Military Elite Cleaning System. As you can see in the photo below, Deluxe Military Elite Cleaning System is fully outfitted to clean everything from a 9mm to a 40mm.
Agencies and units can source the entire line of Otis cleaning products through www.adsinc.com.
