7.62x39 Ar Mags myth debunked

[jkl33]

Hey guys,
I finally got to testing the different Ar-15 mags for the 7.62x39 ar upper and this is what I have found,

So for the magpul P-mags, I used a 20 rounder with a 10 round limiter and found that loading 5 and only 5 seems to work the best. Had the least amount of jams if any.

Next I used a promag steel 20 round ar-15 mag with a 6.8 follower and was able to load 10 into this mag but this one jammed more than i can count. It was ridiculous. whoever said to just switch out the followers must have been on one or something cause they jammed way too much to make this weapon reliable in any situation.

After all this I tried to modify the pmag follower to fit the round round better and still no luck.

I do have an ASC mag specifically built for the 7.62x39 round and compared that mag to the other mags and the lips at the top are longer than the .223 mags. this is the only thing I can see that is the major problem.

If any of you guys have any input I would love to hear it.

What exactly is the myth and how exactly did you debunk it? All I got from your post was that the magazines not meant for 7.62x39 don't work well if you load 7.62x39 in them. I'm curious as I have interest in 7.62x39 ARs.

I use my ASC's all the time.. Is there supposed to be a problem?

ordered a set of 30 rd parts kits to have on hand.

And the difference is the feed lips, angle of base plate and follower. The spring may be stronger as well, but I don't see why it would be....

I use ASC mag for my ar 762 no problem. about 600 round shot so far. Must be something i'm taking or something your missing.

Glad I'm not the only one who read his post the exact same way!

I was thinking of getting a 7.62 upper but didn't know if they were reliable or where to find mags for them. Are the ACS mags the ones to get and where is the best place to find them?

Like all AR Parts depends on the maker and their qc.

I will not name names however their are certain brands / makes I would never dear trust.

There is a reason it sells for so much less than the others.

I have read on alot of other forums that you could use .223 mags for the 7.62x39 round. Alot of local gun shops told me the same thing. All of them said that all you have to do is just change the follower and you'll be good to go. I did that i even tried to modify my other pmag follower since magpul doesnt make replacement followers for different rounds. Whoever said to just swap out the .223 follower for a 6.8 follower was either BSing or had a miracle magazine that fed fine. As for my experience all mags jammed except the ASC 7.62x39 magazine.

and getting ar mags for the 7.62x39 is almost impossible now. Nowhere sells them. They are all on backorder. But the 7.62x39 AR is amazing to shoot. Alot more fun than the .223 in my opinion. Its the fun of an AK with the accuracy of the AR. So far my Custom upper has had no problems. All rounds fired and ejected. and I am using the complete NFA gen 2 polymer lower. If youre thinking about building or getting a 7.62x39 AR I say go for it!

I have C-products 10 round mags for my AR 7.62x39 purchased at model1sales .com with the upper. Mags work fine for me with no jams with 9 rounds load. With 10 rounds the last round sits too tight and may jam the rifle. It seems to happen when the last 10th round is not properly injected. I have not had a problem so far with 9 rounds loaded. My AR works reliably with proper maintenance. I am not sure why the full load sits so tight in AR mags. My Saiga has similar 10 rounds mags and all 10 rounds is easy to load.

No myth, only heresay from people who dont know anything about the subject. I have 10 round C products mags, and 30 round ASC mags and both work flawlessly. Primary Weapons is where I got my 30 round mags but if I am not mistaken they also sell 10 round mags as well. I shoot TulAmmo out of my Doublestar 7.62x39 AR out of the 30 round mags all day long with no issues. You "busted" a nonexistent myth through observation and no scientific data. Next time go out and shoot one first.

... Its the fun of an AK with the accuracy of the AR.

The "fun of an AK" has little to do with the caliber, and unless you are handloading or at least shooting pricey and rarish USA factory x39 ammo, the accuracy is likey twice that of a nato 556 round, even in an AR. The biggest benifit of the x39 is its better barrier penitration over a 556, and its cheap ammo availabilty (usually in the US, and always worldwide). Wrap that into an AR platform, with it's superior A3/A4 optics mounting and superior user controls, and you have a great close range rifle... BUT ONLY if you can get 100% reliability out of the gun/mag combo!
