392 is correct no problem with bolt locking back, just wont go into full battery with more than one round in mag, functions perfectly with one round.

The upper and lower are anderson rifle purchased together as a matching kit. My BCG is not dripping wet so I will give that a try.

Hello all, just built my first ar308 and have an issue with the BCG dragging on the top of the ammo, so much so the bolt wont lock up if there is more than one round loaded in the mag. I have tried two different mags both pmag one 10rd and one 20 rd. The lower is an Anderson Rifle and BCG is Aero precision. What should the next step be? Thanks in advance, Tom
