AK-47 caliber conversion. How I did it is explained.

I built an AK47 kit into a straight blowback gun that utilizes both PPSH drums and mags and in this video I go over how I did it. I also did a check of the velocity of 1980’s romanian surplus and got a pleasant surprise, the 16 inch barrel is a big plus! Ray at Saiga Tech USA convinced me to make this video, but I hope everyone else likes it as well.
