[QUOTE="stenger, post: 972292, member: 26184"] Bolt slop is what causes the top lug to pull away. The trigger pushes up on the bolt which has slop thus causing the bottom lug to act as a hing or pivot point. sleeve the bolt and lap only the bottom lug. I had one rifle go from a .4 to a .2 gun just by getting both lugs to touch on a trued receiver. That action had around .018 of slop on the bolt. Or get a PTG bolt and spec the size bolt body to get rid of the slop. [/QUOTE]
