Pretty Good Breakdown Video especially if you know Russian

At time marker 3:40 he starts to break down the internals and compare them side by side to Systema parts. It took me a while to find this since they titled the video Celsius CTW X-MAX

FYI: That CTW was shoowing ~138 meters/sec = ~450 feet/sec

I was looking at that video the other day. I keep hoping more review/demonstration videos will pop up but sadly they are few and far between.
