DPMS makes a 7.62x39mm upper for a reasonable price, but IMHO don't do it... The DPMS guys don't even like to sell them.
The mags (and 10 rounders are the only ones I can find new) suck. Wanting to shoot that cheap 7.62 ammo in your AR? In my experience most mil-surp type 7.62 ammo has very poor tolerances and does not feed reliably in an AR platform, nevermind the fact that dirty burning powders are the bane of the AR system. If you are wanting something different try 9mm or 6.8 SPC. I have done several rifles now in 6.8 SPC and have gotten very good results. Or if you are a reloader, try 6mmx45 wildcat. They are basically a .223 necked up to 6mm. They run great, using the same bolt, magazine, everything, and there is some great bullet selection out there (like hornady's 87gr ballistic tip). We can get barrels and complete uppers for this caliber. I'm sure some have made it work, especially by using "Frakenmags" cobbled together from AK and AR mags... but for me the "AR-47" just isn't a good concept. YMMV, - HGW |

Thanks,
I already have a pistol caliber upper-.40 in Olympic with .41 AE mags. Works great, just seeing if the 7.62 would be worth it. I will check into the 6.8 mm-don't reload, is ammo readily available and if so how many arms and legs does it cost? |

Recently MidwayUsa has had lots of it in stock for around $0.50 a round...

These guys all seem to be very happy with their 7.62x39 uppers. Of course, most of them have AR47 lowers which solves the magazine issue, but the uppers are identical.
I don't know what happened to DPMS making Franken-mags, but I was under the impression they had started back since the fall of the AWB. Aside from DPMS, you can also get 7.62x39 uppers from Del-Ton, Model 1 Sales, and JT. It's down the list a ways, but I'd like to build one in this caliber. |

For the love of all that's holy
if you want to build a 7.62x39 AR make SURE you run it on an AR47 lower Hi Cap mags will not work with the magwell setup on an AR15 lower Barry |

Who shot the Colt factory 5 round mag? Are they reliable?

I have a Model 1 Sales 7.62x39 upper and it shoots about 2-2 1/2 MOA. It feeds everything I give it. I have a handfull of the 20 round Frankenmags and they work slicker than snot. The round works well on deer and I've had no issues.
Finding high capacity mags is the only real issue with 7.62x39. The Franken mags are the only high capacity mags that work well (top of mag is straight wall like and AR mag but the bottom looks like a AK mag. There out there but you gotta keep looking. |

The Colt 5 shot mag that came w/their version of the rifle was nothing but a standard 20 roiund .223 mag, w/a 7.62 marked floor plate, and an internal block to keep you from loading more than five. Worked just fine-----and so will any 20 round AR mag. In fact, if I remember right, the regular, unblocked, 20 rounders will actually do OK with 6 rounds. Beyond that, the body taper of the 7.62 round starts causing problems |

The DPMS runs fine. DPMS is making frankenmags again. When I bought mine, I posted the price and part number, so it is in the archives somewhere. The frankenmags are well made and run like gangbusters!!
 They hold over 30 rounds, but I can't count much higher than that.  I have heard that the bolt will eventually break, because a bit of material is removed to allow for the larger case, but it hasn't happened to me, yet, and if it does, I won't mind buying a new bolt. I can hit the silhouette targets out to 300M with the irons on a 20" bbl. Groups were very reasonable, but it has been a long time since I punched paper with it. I don't see the AR platform as a bench rest rifle, so I don't get hung up on sub MOA groups, particularly with cheap Ruskie ammunition. Get one, it is well worth it!!!

OK. With a little more research, I have found that Oly also makes a 30 carbine upper that uses M1 mags. I have 2 M1's and beaucoup mags-this looks like an option. Any word on how this setup works / shoots for accuracy? I think this would definitely qualify as "something different". Thanks in advance.
