Otis FLEX Cleaning Kit Features The Otis Technology FLEX uses a flexible cable-based cleaning system rather than a rigid rod reducing the chance of the cleaning tool contacting and damaging the crown of the barrel during use. This design is particularly useful in the field where a rigid rod can be awkward to maneuver through a chamber or around obstructions. Built specifically to service .30 caliber rifles the kit is matched to the bore diameter for an effective thorough clean. The compact packaging keeps the kit organized and easy to store between uses. Because the FLEX system folds down small it travels easily in a range bag backpack or vehicle without taking up significant space. This portability makes it a practical option for hunters who need to clean a rifle in the field after exposure to rain mud or dust. Otis Technology has built its reputation around flexible durable cleaning systems designed for exactly this kind of field reliability.
