4th time out this morning....
Ported bbl port up to .086"....also ported dial.
Ejection on dial settings 7 and 6 were strong....5 seemed okay at first...went to 4 and had a bolt over base malf. Dialed up to 5....same problem. Not sure if it's problem mags or still a gas issue.
4 and 5 both seem undergassed still. Problem mags were #7 and #11. Both had bolt over base malfs and failed to lock back on empty.
Noticed that the problem mags I sent in for warranty and these 2 today have a similar oddity....after being fully loaded to 25 rounds and having a bolt over base malf....once I clear the malf and continue on with that mag until empty....the follower will make a popping sound if you press it down into the mag body about 1.5" or so. Mags that worked properly do not exhibit this popping/binding issue when pressing the follower down. Once the "pop" occurs...the follower even in problem mags cycles smoothly by pressing down that same 1.5" or deeper with your finger.
