Otis M-16 Butt Stock System
This 1/2 lb. cleaning system replaces over 3 lbs. of conventional gear and
fits into the stock of the weapon. With the flexible cleaning rod it is only
possible to clean correctly, from breech to muzzle. The receiver, locking lugs,
chamber, shoulder and neck can easily be cleaned. Bore obstructions, mud or
snow, can be dislodged out the muzzle end. A stuck empty case or bullet lodged
in the neck can be easily knocked out.
