Will this work for an M-70 milled receiver? (Hoping to catch CarlosC's eye)

Just like the title says I am interested in replacing the barrel on my milled Yugo M-70. I know that the Yugo is kind of a beast unto itself for many of it's parts so I need to know if this barrel is the correct size(s) to fit the receiver, rear sight base, gas block, and front sight base.

New Manufactured AK47 1970 Barrel

Also curious what has been done (or not done) on Green mountain barrels (from those of you who have personally worked one).
Like:
cut out on chamber end
Gas port hole
etc.

Thanks in advance for your knowledge on these,
Nico

 

Thanks for the the reply CarlosC.

I guess I am stuck waiting until they are in the office (Monday), and calling them to find out what the dimensions of that barrel is.

Hmmm,
Looking at your data, and the measurements I took off the barrel I pulled......My old barrel is really close to the dimensions you provided for an Yugo AKM (not your milled Yugo Data).

Here are my measurements from the barrel I pulled.
Receiver= .910
Rear Sight= .730
Handguard retainer= .688
Gas Block= .631
Front Sight= .591

Compared to your Yugo AKM data:

So I am guessing that I have a milled AKM Yugoslavian rifle.

 

Talked with Dennis from Green Mountain barrels today about the AK47 (1970s model) that they have for sale.
He was nice enough to pull one from the assembly line, take profile dimensions of it, and call me back.
Great news is it's the correct size for my Yugo M70

I ordered one on the spot, and it should be on it's way soon.

 

I have received my new barrel from Green Mountain barrels today.
It is an EXACT match for the barrel I pulled from my milled receiver Yugo M70.
Here's the dimensions as I measured them from both barrels:
Receiver= .906
RSB=.728
Handguard retainer=.688
Gas Block=.631
FSB=.591

Some pictures of the new (chrome lined) GM barrel next to the pulled barrel from my rifle>>>
(the end of the old barrel has been cut shorter for re-crowning, and the new still has a protective cap on the threads)





I recommend talking with Dennis at Green Mountain Barrels as his customer service is fantastic.

 

I am happy as well.
I'll post some pics, and give a range report when I get it all together.

 

Range report:

Impressions of Green mountain barrel during installation:

Gas block, and RSB were tight press fits.
Both receiver, and FSB were press fit but more loose than I would have liked.
I had to clamp the barrel/receiver six ways from Tuesday to keep the barrel from being moved (we're talking .001 of an inch here now) while drilling the barrel pin hole through the barrel. FSB could almost be twisted on (with a cheater through it).
All was close enough to make work though.
I took it out for a test fire, and to sight in today.
Ran like a champ. No issues at all through about 100 rounds.
It was windy but I gave it a go at 100 yards with some Wolf Black Box, and using a 5MOA cheapo red dot. It covered almost all of the 6" shoot'n'c targets at 100.
Here's the rifle, and results (11 shots at 6" shoot'n'c' 100 yards, and rested on my range bag):


Not bad at all IMHO.

 

Agreed.
I was most impressed with accuracy out of the Green Mountain barrel.
A windless day, and some better ammo, and I am sure the groups would tighten up more.
Best $155 I ever spent. After the time, and effort to re-weld that milled receiver it's nice to have a new barrel on that rifle.

Now to touch up the cold blue on the receiver (had to scotch brite the front of it because of some marks I put on it while working on it), and I can move on to the next project, and just enjoy shooting this one.
