Otis Technology M-16 Soft Pack Cleaning System 223 BX is a portable cleaning unit packed with all the essential tools for weapons maintenance. Tucked away in a small, 11 oz soft pack carrying case, this cleaning kit allows you to clean your M-16, M4, or AR-15 rifle virtually anywhere you go. The Memory-Flex cleaning rod allows you to follow the natural path of the bullet for a more holistic cleaning method that actually ejects residue from your weapon instead of packing it back into the action. The cleaning rod wouldn't be useful by itself, so Otis Tech has also packaged a set of cotton patches, a brass slotted tip, and a 0.5 ounce tube of Otis O85 Ultra Bore Solvent with the Otis M16 Softpack Cleaning System. With these tools, no part of your gun's anatomy is safe from a stern scrubbing. If your bore becomes blocked, you can use the included brass obstruction removers to quickly clear stuck cases, mud, and other bore obstructions. In low light situations, the bore reflector makes a handy addition to this Otis Technology cleaning kit, allowing you to inspect the interior of your bore with nothing but the reflector and a flashlight. For a compact, portable weapons cleaning kit that helps you perform maintenance on your .223 caliber rifle, purchase the Otis 5.56mm Soft Pack Cleaning Kit.
