The Lock-N-Load Sonic Cleaner can hold up to two hundred 223 Rem cases or one hundred 308 Win cases. The Lock-N-Load Sonic Cleaner is a combination of intense ultrasonic cleaning action and One Shot Sonic Clean solution, which provides an extremely effective and efficient method to remove carbon residue and other foreign materials from the entire case. Unlike tumblers, this sonic cleaner quickly cleans the inside of the case as well as primer pockets. The ultrasonic action creates microjets that blast carbon buildup off cases, small gun parts and equipment.
