Barrel for 7.62x39 AR build

[sevt_chevelle]

Looking at building a 7.62x39 AR, wanting something to run steel cased ammo through. I have several 556 builds all ready and a few spare receiver sets laying around.

Any suggestions on barrels, am leaning towards a 16" middy?
Thoughts on these.

What barrels are you guys running?
Thanks.

I used this on my build. Haven't gotten a chance to shoot it, so I can't attest to its accuracy yet.

save your money and get a bear creek, all there barrel over 14'' have a 1moa guarantee.

I also second the bearcreek, I bought an upper and it's great so far. Best group was 3/4 of an inch at 100 yards and I am by no means a good rifle shooter. Very impressed, in my opinion best bang for the buck.

My exeperience & observations of BCA barrels indicates your odds are no better than 50/50.... Likely you’ll eventually get one that shoots well enough but it may take 1-2 friggin RMA’s... Why risk it?

At least in 5.56, Nitride barrels are available from Brownells, KAK (Green Mountain blanks) Valu-Line, sales on Ballistic Advantage, Right to Bear all offer better barrels for not much more loot. For chrome-lined DSA are great for the money.

Choices are fewer with x39 but here a handful of KAK barrels. Their 16” Nitride Valu-Line barrel is $110 bucks... The Faxon barrel(s) you mentioned are also GTG.

IME shooting bi-metal bullets, a Nitride or chrome-lined barrel will be more durable than plain phosphate.

Does anybody know if the bear Creek barrels have a .308 or a .310 bore?

there .308 from what i seen they shoot both bullets good us and euro spec ammo good to.

I had a Bear Creek on one of mine, and it shot Wolf and Tula ammo into very good groups! I could not believe my eyes...

I WOULD say I prefer to “cry once,” but I have found I don’t even cry any more when spending more for my barrels. The results are worth the cost for me, and headaches never worth the savings.

Nice shooting. I have some similar rifles in that caliber and concur with you.

carbine gas system but i have the 12.5 inch and have had no trouble was even shooting great with golden bear, was able to harvest 2 deer this year with it accurate enough for neck shots on both deer.

Another vote for KAK industries. Have not had any problems with mine.

Were I of a mind to build one (and I'm toying with the idea), I'd go with KAK.

I've got a AR Stoner 7.62x39 upper and it's a great shooter with my handloads (.308 dia. 135 FTX and CFE BLK) killed 2 deer with it this season and results were as expected. Shoots 1.5 MOA with either Wolf 125 SP or the Wolf HP.

I've put together a x39 pistol with a 10.5" pistol upper from Hardened Arms and WOW color me impressed. Probably my favorite firearm and shoots small groups with the factory 123 SST ammo.

I've been eying this Green Mountain barrel: http://www.gmriflebarrel.com/gm-m10-16-7-62-x-39-mm-ar-barrel-1-9-5/

I also went with a Bear Creek Arsenal barrel on my 7.62x39 build. It's done well so far and I like the heavy profile. Primary arms has then for $59 right now but they occasionally go lower (it was $49 when I bought it):
