I was a tad uncertain about the DEZ barrel only for lack of info going into the build. But I really like the DEZ barrel and RCA BCG. Sounds like our uppers are almost identical. I really need to get some good ammo and put it through this thing. I am pretty sure this is an MOA gun or better. But either way my only criteria was for it to be more accurate then an AK so I think we're good lol.

Thankfully it also loves & digest Golden Tiger & even cheap Wolf WPA bulk ammo.

Gas port on this barrel seems to be spot on. Its carbine length and port size was .098 IIRC? So on the large side. But it ejects nicely (right at 3:00) and the recoil impulse isn't too bad so I am going to leave it alone. MOA at 200 is awesome. The more I shoot this thing the more I love this round. I shot that 10 round ragged hole using Wolf so I have high hopes for when I break out the nicer ammo.

Let me know if you find a good source for quality ammo...I've got some brass case PPU that does slightly better than the steel case, but haven't been able to find any precision 7.62x39 ammo anywhere. Haven't looked recently though to be honest...

Me too! So much MORE FUN than a 22/5.56, haha! I call it the “308 Win Short”!

And I doubt you ever will!

While the AR platform certainly helps deliver or exploit whatever inherit accuracy is available/capable from a good –39mm cartridge, me thinks that the words ‘precision’ and ‘7.62-39mm’ are mutually exclusive, lol!

Besides, remember the famous Russian axiom, the epitome of the AK & its rounds … “Quantity has a quality all its own!”

I think the most you can hope for when discussing "precision" 7.62 ammo is that it not be steel cased lol. And lets be honest here. Part of the reason you build a .39 is because of cheap ammo. I'd still love this thing if it was a 4 MOA gun. Maybe just not quite as much.......

Not when you load your own ammo using quality bullets...

Of course but that pretty much holds true for most any caliber. Talking commercially available ammo here.

About that, it's called "Lapua" and it's from Finnland.

They take their 7.62x39 accuracy seriously.

Can't find any for sale stateside. But I did read the specs on the Lapua web site. I would love to get my hands on a few boxes to try it out.

here is mine, aero lower and bca side charging upper. runs like a top and accuracy is good. I did a spray job on the mags and cerakoted the rest
