I fired my SKS at the edge the other day. Sitting down in a chair, back staight, I made 5" grouping from 50 yards out. I don't know if thats good or anything but it worst than the UZI 9mm and similar to the M4. My shots had like 2 second pauses becaue of recoil. It seems to shoot nice. Now I just need a 75 round drum and turn it up to 900 rpm.
But yeah, I guess it did what it was supposed to do.
