MDRX Rivalry: 300 Blackout

In today's MDRX Rivalry video, we discuss the 300 Blackout conversion kit for the MDRX. The 300 Blackout was put on a temporary production pause which will soon be suspended and 300Blk kits will again start shipping. In this video we go over the intricacies of the 300Blk conversion kit and information you should know. Especially the part about gas settings, the 300Blk should always be run on the lowest setting that will reliably function the rifle. Operating it on a higher gas setting will cause damage to the gun and render it inoperable.
