Just bought a IO Stg2000c AK47, had to use the firing bolt out of my Norinco as this one would not fire the rounds, it looked as if the firing pin had no rounded tip and was flat and there was no protrusion, took it out to the range today and fired about 120rds, thru her, very accurate other than the elevation was off by by 500 meters, meaning that shooting at a pie plate 12" target from 26yds I would not even hit it, ***, so after making rear elevation changes, no tool yet for the front sight! set on the 500 meter mark I was putting it inside a 3" target, my Norinco would not never do that, got home from the range and called IO and they are going to send me out a new bolt with pin asap, this rifle is light at about 6 lbs, so far I do like it but more testing to come and you can not beat the price, thanks
