I've seen LWRC, KAK, POF, PSA, Colt, you name it have similar needs. I think the one that was -7 was a mutt. Anderson lower I think (could be anything), stripped upper, etc. Try it with your rifles. Take every AR you own that shares a lag and load the mag to full. Insert the mag, if you have to force it or smack it, remove a round. Once you have where every rifle you own with easily lock a mag in with the bolt closed WITHOUT needing to smack the mag to lock it in or otherwise needs to be forced in that is where you can load your mags because it will work.in any rifle you grab.
Welcome to what we call tolerances. When they don't stack the right way it looks like that.
Havnt experienced issues like that with the AK. My VZ58 likes -1 because everything is still wearing together.
