Otis Technology, under its new Otis Defense branding, will be releasing a brand-new product at the upcoming Warrior Expo East 2017 show, Otis Big Bore Cleaning Equipment. This product is designed to service artillery, mobile artillery, and even the main gun of tanks, and utilizes a sock and disk system which expands to fit the bore for more effective cleaning. It will be available in 105mm, 120mm, and 155mm bore sizes. If you happen to make it to this year’s Warrior Expo, you can check out the Big Bore Cleaning Equipment at OTIS Technologies booth 1205.
