I have bought some of their M14/M1A mags in the past and have been happy. But the ones I received today had quite a bit of rust on them, way too much rust. I am sending them back of course. FYI-Be warned.

My guess is that they are scraping the bottom of the barrel.
The six I purchased during the first month they were offered
were clean, one had a busted weld – Armalite exchanged it N/C.

All USGI parts are in short supply.

I wonder if they'd exchange one of the six mags I bought from them in Dec. The other 5 run flawlessly, but this one will not allow a round to be chambered without me helping the bolt forward manually. I checked it against the working mags and could not tell any difference in clearances, etc. But the rear of the follower was cracked and evenually busted off. I still can't see how that'd make a difference. Wonder if I should email them and ask them to exchange it...

I'm sure they will, but keep in mind return postage is on you...
