I'm slowly moving ahead with the most perfect build I can do, looking for the most accuracy. I'm paying attention to fine details. There was on-line an item about a guy who lapped AK bolts. As I remember you could send your stuff to him, before assembling the receiver, and he would jig it up and lap the bolt to get even bearing on both lugs, just as anyone accurizing any other rifle would do. I'm unable to locate the site again. Does anyone have a link to it? Any ideas or thoughts on DIY bolt lug lapping?
