At the time i did not recommend this product...but - Ammunition Storage Components 7.62x39 Stainless Steel 5 Round Rifle Magazine

In addition to buying these 10-round mags, I also purchased 30-round mags from ASC directly from their website, thinking at the time they weren't available anywhere else.

I had issues with feeding due to burs from poor machining. The followers kept dragging and causing all of the magazines purchased to fail(FTF).
Lubricating the insides had minimal improvement. The issues still occurred, but not as much. Getting frustrated, I tried brass ammo from my good old Russian surplus. It was the same result, but this time, I only had FTF towards the last 2 or 3 rounds when the spring tension loosened up. Again, this was so frustrating and I decided to buy CPD(C Product Defense) Mags aka Duramag. Regardless of the ammo those worked flawlessly with no issues whatsoever.

Over a few months, feeling like I wasted my money on all 10 ASC Mags, I decided to get a hold of someone from there, before either using a Dremel on them, sanding them down, or throwing them away. I explained how all the magazines I bought had the same issue with the FTF at the end of the loaded magazine, provided photos, and videos, they gave me an RMA Number and I sent my 5 10rnd and 5 30rnd mags back for repair. After 2 weeks of follow-up, they replaced all 10 of the magazines with a new batch that was smoother than any of the ones I originally purchased...WTF??Really?!!! They said, they were not repairable and gave me a new version of the 7.62x39 AR Magazines.

I did not recommend this product...but after contacting ASC Customer Support, they sent me replacements for my entire set of magazines that I ordered from here and from their website.

The new version of the 7.62x39 magazines is much smoother and feeds flawlessly.
