My first build works perfect. Just test fired my second and having a little trouble.
without a mag in it cycles smooth, but with a mag in the bolt is binding up against the mag. If you look at the top of the mag it is hitting on the right side oposite of the extractor.
When I was putting it together I had to grind down the extractor a little because the bolt was binding on the right side of the front tronion. Where should I grind or how do I get the bolt+carrier to move to the left a hair.
is the mag in there straight? 7.62 i presume......did ya take some off of the part of the rail that sticks out in the magwell at the dimple(non ejector side)??
