Hey folks,
I just checked my old receipts to make sure about this, so here goes. In January 1996, I purchased a bunch of 30 round magazines for the Colt AR-15 in 7.62X39. They were blue steel and definately did not look like the 30 round magazines for .223 rounds. I purchased them from Eagle Exim Inc., 435 23Rd. St., San Francisco, CA 94107, and they cost about $27 each with S&H included. I have no idea if they are still in business, but their telephone number then was (408) 358-5586. The product code for the magazine was 290-EXC-133, but I have no idea who made them since there is no name on the mags. They look somewhat like USA mags, but I cannot say they are USA made. I can say, however, they are the real thing. They have functioned flawlessly for me since I have had them. While I do not get them filled with dust and dirt as in combat conditions, I can say that I keep them filled to capacity when not in use. They are called 30 round mags, but they really hold thirty-one, and a couple of them actually hold thirty-two rounds for some reason.
While checking my old receipts, I also found some purchases in 1995 of Thermold magazines for my AR-15 in .223 and my Ruger Mini-30. Some of the Thermold mags were the 30/45 colapsable type also. I found all of the Thermold mags to also function flawlessly in these two rifles.
I wish I could tell you more about the mags for the Colt AR-15 in 7.62X39, but none of the mags have any markings on them to indicate their manufacturer. I do still have the receipt for them, but I have already given you all of that info above. If I can be of any further help, please do not hesitate to contact me via E-Mail. I have heard a lot of bad stuff about mags for the AR in 7.62X39, but my mags have simply not been a problem. I really like AR in the 30 cal, and I am sorry to hear others having problems. My advice is to see if Eagle is still in business, and, if they are, identify the mags I purchased and see if you can get the same kind.
Best wishes,
Dave Wile
