Default Why build a 7.62 x 39 AR ?

I know the ammo hits harder than the 556 stuff and I assume the reputation of being less accurate is because much is fired through AK's, But the accuracy of the ar with the punch of the 7.62 x 39 ammo sounds like a good combo, not to mention the 7.62 ammo can be cheaper.
Anyone?

Why not build one?

I think that is my next AR build... I think a 7.62 AR is a great idea.

My main apprehension would be magazines. I think 6.8 would be better choice from that standpoint, while having semi-common magazines. Yet retaining similar ballistics. Plus 6.8 is common enough now that most shops carry it.

You may want to study terminal ballistics. While 7.62x39 has more energy, the 5.56 creates a MUCH more devastating wound. Put it through a 20" barrel and it will hapen to 200 yards.

7.62x39 is similar to 30-30 so you could use it for hunting pigs and deer if you wanted

If you are only going to have one AR or build your first, I would go with the classic 556/223. For my one and only AR, it's going to be a 10" 556/223 ar15 pistol. I thought about doing a 9MM or a 7.62x39 or even 5.45x39 to keep the ammo common with my AKs but thought, it's a friggin AR, gotta have one at least chambered in what it is suppose to be.

Well, I waited long enough and found what I think a great deal on a hardly used CMMG 10" complete AR15 a2 flat top upper.

IDK the thought of my 10in AR15 pistol, just gets me excited to get it built. Something small but with the 10in barrel I get a good amount of omph and accuracy behind it. I also thought of going 7.5 super shorty but for my only one I'm going 10in then later on I can get the super shorty when I get more $$$.

From what I have researched, magazine issues sound like they may been resolved , esp in the shorter ca 10 rnd mags. I know in 2007 and 2008 everyone had issues with them. And if I had to live with just 6 rounds in the mag I could live with that.

Being my 3rd possible ar I already have a 22 and a 556, so I am looking at the next one. I realize the 7.62 does kind of fall off after 300 yards so it wouldn't be as effective as the 6.8 in long distance targets. But getting 6.8 ammo and it's costs are concerns I would have. 6.5 looked even better, but costs and availabilty were an issue once again.

My next ar may be a 308 so that might resolve the long distance issue as well as more plentiful ammo.

The mag issue is an older issue which CProducts has resolved. I have four 10 rounders and all of them function flawlessly.

Why a AR in 7.62x39? Because it's cheaper to shoot than .223. My M1S upper is just as accurate as the HBAR 5.56 upper I sold. The main reason I got my 7.62 upper was because it seemed I was spending more money buying all sorts of different caliber of ammo, so I decided to consolidate. I have an AR and AK in 7.62 and eventually will add an SKS. So that means I can buy 1 caliber ammo and it'll work in all three guns.

Its cause you can, I built one shot it and was happy with it then sold it. Decided I want to keep my AK47 rather than a 7.62x39mm AR. Ak47 far more reliable, besides 7.62x39mm is a much dirtier round

It'd be interested to see an AR shooting 7.62 x39 and see how it performs. I think the round will shoot great in an AR. You can shoot it all day long without hurting your pocket.

I think I would go with the 6.8. It's much the same as the 7.62x39. But I wonder if the 6.8 is going to be more common.

b/c my other 10 ARs/AR pistols and two sig556s are 5.56...so my next two ARs are going to be 7.62x 39 pistol and 9mm carbine !

Why blonde over brunettes?

Variety is the spice of life....

You seen the cost of 6.8 ammo yet? Even if you load your own, it's still an expensive round.

Most of my AR receivers are set up for one upper only - I don't do alot of switching out. The one I do switch out has a RRA 2 stage trigger and an ACE full length skeleton stock, the uppers I use are both flat tops, a 223 cal 16" bull barrel (no brake) with 4 to 14X scope and a 7.62X39 16" with a DNTC brake and a 1.5 to 5X scope. CProducts 10 round mags in 7.62 work perfectly for me.

Default AR15 conversion to 7.62x39 magazine, just change the followers?

Can the regular AR 15 magazines be changed out to hold and feed the AK rounds by just changing out the followers or is there more to it?

Was thinking of building an AR in the 7.62 x 39 configuration as well.

Thanks,
Eddie

Don't know, but the 10 round C Products are cheap so I wouldn't bother. On +10 rounders no.

Unless I'm missing something there isn't a price advantage on ammo, more of an issue of finding a need for 7.62 in an ar platform.

Personally I am leaning towards doing one in 7.62. I have 5 extra stripped lowers so there's my weak reasoning excuse.

It will only feed a couple of rounds till it malfunctions non stop. If your gonna spend all that money on a 7.62x39 AR, why not just spend the extra $35 or whatever on a 7.62x39 magazine. Even a 7.62x39mm mag is usually finicky.

Default Thanks for the input on AR15 conversion to feed AK rounds.

Thanks... wasn't sure if just changing out the follower would do the trick to convert some of my other regular AR Magazines I already have on hand.
I'll look around for magazines already set up for AR with 7.62x39 ammo.

Any one recommend any upper receivers for this configuration?


Thanks in advance,

Eddie

For me, here's the cost advantage of an AR in 7.62. I have 2 rifles, both 7.62x39 so I buy 1000 rounds of 7.62x39 at $229. Before when I had 1 rifle in .223 and 1 rifle in 7.62 then I was buying 1000 rounds at $209 and 1000 rounds at $229. In essence, by moving to one caliber, I'm saving $209 (I know, not really but that math works for my wife).

I see your point. But I have 2 aks and 1 ar so I need both ammo anyways.
