Did you take them apart for a quick wipe down and uniformity check? I always try to do this with new mags before they get put into rotation.
What were the courses of fire like? I have seen a few 3 gun matches; but never a carbine only.
I have heard that PMags are different; I just never had a problem with my steel mags to make me start buying those expensive fuckers.
Pmags are expensive??
Finally filled up my MTM AR magazine can. Ended up loading up 15 30rnd mags for the can and another 7 mags as spares. My thumbs are sore. But I'm a little worried about leaving the mags full for extended periods. All Magpul mags. Any thoughts?
. I also shoot enough that I should know by that point that the spring is going out.Could just leave them empty and get one of these... assuming everyone keeps their ammo in nice 50 rns boxes.

.. but it would save your thumbs! But yeah, there needs to be one that lines up shit for you.After form 3&4 appoved ...~ how long before you receive stamp?
I was under the impression that it isn't the static load on the spring that causes issue, but the cycling of loading and unloading.
