Ammunition Storage Components 7.62x39 AR-15 Magazine - 10 Round

I purchased two of these for benchrest and hunting as I did not want a long magazine getting in the way. I have typically loaded it to five rounds, and it gets used at most a few times a month. I have also used it with 6.5 Grendel again only loading 5 rounds.

Today during a range session I fired four shots when the last shot failed to feed and upon removing the magazine I found the follower about halfway down the magazine with one cartridge still in place. Assuming that perhaps the magazine was just dirty and carbon fouled from suppressor use I took it apart to clean it and found the spring in about five pieces. My local range did have a choice between ASC and duramag in 10 Rounds however I chose to replace this with a Duramag. I did send pictures to ASC and I would be thrilled if they would send me a new spring.

Note: We are happy that we were able to speak to you on this and get you taken care of. Please let us know if there is anything else we may assist you with.

Unloaded, it fit well. Once 2 out more rounds were in the magazine, it didn't easily fit the mag week anymore. Have to bang it into place and really work to get it out if you don't empty the mag.

Fits and feeds good.

I have 4 of these and all of them have zero problems after about 100 rounds feeding, loading or ejecting. If you have the gas adjusted right there should be no problems locking the BCG back and I put a Super 42 H2 buffer (much love for the super 42) and spring so no failures to feed either. I have not tried the Duramag yet but I have not had any of the reported issues with the ASC mags.

works great, no problems

no problems with this mag

I bought these in combination with a Diamondback 7.62x39 16" barrel. When loading the magazine with 9 rounds I have not encountered issues. At 10 rounds there tended to be some issues with feeding the first round. Fine for my purposes but I could see how someone would get annoyed by not having a full 10 rounds in the mag. For that reason I took off 1 star. Beyond that, these work great.

I bought 2 of these to try in my first AR47 build, along with 2 CPD ones. Construction looks good, nice finish. No failures to feed (Faxon 16" barrel in Aero Upper) in 160 rounds. As another reviewer noted, the springs were quite stiff when loading 8+ rounds, but did get better the more I used the magazine. Feeding was also a bit sluggish at first, possibly due to the spring, or maybe feed lips. The only reason I'm giving it 4 stars is that these drop out of one lower, but have to be pulled out of another, where the CPS ones fall free from both. Still, I'm happy with them.

Purchased this magazine and while getting the 30 rounds out for a range trip, found that I had already purchased a 10 round in the past. I use the 10 round mags when shooting from a bench rest. No problems with failure to feed using Brown Bear 123 grain HP ammo from either 10 round magazine or 30 round ASC magazines. My carbine build is a couple years old so I do not remember what brand of BCG or barrel. I have a Spikes upper and lower and buffer/spring. No problem loading 10 rounds by hand.

They look good and well manufactured. Started putting rounds in and at the 9th and 10th round it felt like i was pushing against a truck suspension spring in a 7.62x39 mag. Hopefully the spring loosens up a bit.
