Christmas Present to Myself

[Neuraleanus]

This is what I did:

I left the follower itself alone. I compared the height of the follower hump to the one that was working and found them to be identical. I also noticed that the right-most tab on the mag body was bent up more allowing a higher follower hump over the top edge of the mag. Upon hammering the tab a bit this reduced the follower height and I was able to make the follower profile appear more like the other mag. The result is rounds are no longer popping up out of the receiver, but sometimes the right-most cartridge will get stuck. The other mag does not do this. The left-side tab doesn't seem to have much of an effect on the follower position. I have not touched the rear tabs. Not sure what to try next.

Break through:
At least for this rifle, sample size of one, not only is the degree of bend of the front right-most tab an issue, but so is its shape. In comparing to my other mag I noticed that the rear corner had been removed. Upon filing this corner a bit the problem of stuck rounds was greatly diminished. Rounds are cycling much better now.
