So I do not pirate dfin's post about his jamming problem, here is mine. I fired mine again today and after about 60 rounds for the day (between 450 and 500 total rounds fired now through this my second AK from IOInc) I started having jams. First rifle had barrel mounted canted to the left. This one has been great until now. Firing Yugo ammo,the bolt hung open nearly fully to the rear, and it appears it is just lifting out of the rails when coming back forward. It is pretty difficult to unjam. Because of the problem with the first rifle I have been without my AK as much as I have been with it since paying for it, and do not look forward to doing that again. This new rifle came and they forgot to mount the scope rail on the left side of the receiver. They sent me the parts to mount it plus the quick releas rail for the scope to mount on for my trouble, but where is the QC? On a good note,I shot pretty tight groups with it today on the 100m range. But AKs dont flipping jam right? Four jams in two 30 round mags. I will take it out this week one more time to verify, but i am done if it happens again. I hope IOInc will just refund me for my time and trouble. I was originally gonna buy an uncompensated Norinco, but the wife let me buy this and another pistol instead of the more expensive chicom. Shouldn't have been greedy I guess.
