So it changed, for the first year or so no issues. Currently been fighting it for forever though.
I thought this might be the case as well but I checked it every time and found the spring wasn't binding up, at least not from this issue.

This looks like the follower that came with my gun and I don't see any nicks/burrs or anything on it that would catch. What work do you do to the factory follower? I tried a low drag phase 5 follower for a little bit because I suspected the follower but it ran about the same.
This is a good point on the mag spring, I generally bend the cut side a bit but I will try what you are saying and see if that helps.
Some good points! I'll play around with the follower/mag spring again and double check that the carrier dog isn't wobbling around.
