Matt from OHUB LABS recently met up with Joe from Dakota Tactical, makers of some of the finest roller-locks in the United States, for a day full of shooting machine guns. In this clip, Joe shoots a D300 (a super-cool roller-lock based on the HK53) in full auto and blasts apart a watermelon. It's all recorded in glorious slow motion video using the edgertronic high-speed camera. Visit Dakota Tactical at http://dakotatactical.com/.

We used Freedom's sub- and supersonic reman loads in this video.
