Green Mountain AR-15 Barrels?

[SA80Dan]

Anyone know if the 1:8 twist 20" Green Mountain M16A2 barrels have the M4 style feedramps?

Old thread, I know, but I have one of these barrels, and I noticed that someone asked about the chamber. Mine is a 1:8 twist 20-inch M16A2 barrel (to the poster above, I would check for you but I'm not at home).

My statistical sample of one, but mine has a 5.56 chamber. I shoot 5.56 almost exclusively (mostly American Eagle XM193 and XM855, with some Black Hills Mk 262 mod 1 mixed in). No popped primers or gas staining or anything like that, and it is actually pretty accurate.

EDIT: SA80Dan, mine has rifle feedramps.

I just got my Samson Evolution 11" handguard today and finished my rifle with the Green Mountain barrel. My plan was to build a low cost/light weight rifle that I could carry comfortably all day if needed. It weighs in at 6lbs, 8.25oz as pictured. Gonna shoot it this evening hopefully.

Nice Job

Let me know if you have problems with your EVO rail. I had problems with mine and sold it. No matter what I did, the rail would pull forward off the barrel nut. It was fine offhand but once on a bipod, the recoil would pull it off.

I made a thread in the custom build forum.

Where did you find the 1/7 fluted? I don't even see that as an offering on their website...

They don't sell them direct. A place called Gunkings is one of their dealers. They are sold out now but you can sign up to be notified when they are back in stock. I had to do that when I wanted to buy one and they had them back in stock about a week after I signed up.
