    Alright- ran some tests today.

    First off- for the original, the bolt was open. My bad- forgot to mention that. I had finished firing the rounds in mag 1, bolt was locked back as I inserted the problem magazine.
    Also, fwiw, I do not have a problem inserting a full magazine on a closed bolt with either a rifle or hangun.

    So I got the rifle out today, locked the bolt back, inserted [empty] mag in the normal way. Then I slapped the hell out of it. No result.

    I did manage to replicate the problem in two way though:
    1) With bolt locked back, inserted magazine, depressed release button and smack. Perfect replication- took like 5 minutes to get the mag out. Now granted- duh. of course it's going to do it this way.
    2) Insert magazine about halfway, then smack really hard. Perfect replication again.
    I think this must be what happened, as I had mentioned originally. I got a little frustrated during the mag change- one of "those" days shooting- and I must have smacked it harder than I thought. And I can't for the life of me figure out how I would have manage to depress the mag release at the same time anyway.
    Yes, I am QUITE aware smacking the magaine in is NOT the correct way to do it, and fwiw I hadn't up till that point- like I said, one of those days. I will assign myself 15 minutes of flogging as penance.

    Now I did manage to get a partial replication another way- I took the magazine and beer-canned it into the gun as hard as I could. There was a slight "slide-click" and by looking at the opposite side of the magazine release (the bar side) you could see it was partially pushed out. However, it didn't seem to stay in this position and would slide back down to where it's supposed to be with minimal effort.

    I decided to re-try this method with a new magazine (Pmag) as the one I was currently using had the catch cutout pretty much trashed from the previous two replications. I also dug out a second rifle with a Spikes lower to compare.
    Using the new magazine I beercanned it hard again. On both lowers there was still a slight "s-lick", but I watched the mag release when I shoved it in, and there was only slight movement in it. So I'm assuming everything's normal with the lower.

    The new Pmags as seen at SHOT have a stop to prevent this.
