One of the first InRange videos included a mud test on an M1A (M14) in a modified Troy stock.
Recently we did a similar, yet more controlled, test on an M1 Garand. With not only our videos, we see people stating that the AK47 would have breezed through, along with many requests to perform the same test on the AK. Well, here it is. The AK47 mud test, InRange style.
