barrel question for the hoarde?

[tackdriver]

I took a chance on a used grendel barrel that someone had tried to shorten themselves. This person said it was AA but I have my doubts, the bolt that came with does have AA on the side. One of my main questions is, did AA ever use barrels that didn't have feed ramps on the barrel extension?

Nope!

I didn't know anyone made finished barrels without feed ramps.

I think what I an looking at is throwing me off because I just built a 18" for my dad and his barrel had m4 feed ramps. I see this barrel does have feed ramps but not as robust as the barrel we installed a couple weeks ago.

B.Waited, the barrel is stamped 6.5 grendel but does not indicate twist. Do you know if that follows AA's mo?

When AA first came out with the Grendel barrels, I could have sworn that the ext on AA's barrels did not have M 4 ramps. Now I could be wrong, keep in mind this was a long time ago. So bwaits could be right and I'm just really wrong.
