AR-10 308 Barrels

[whitewalrus]

Any AR-10 308 Barrels around the $300-400 that anyone recommends? I was thinking of going with a 20" Criterion in my Aero M5 build - any feedback on their barrels?

It seems to me that Criterion has had some difficulties recently (or, that others have had difficulties with Criterion barrels).

Historically, they've been great: I have a Fulton M110 built on a Criterion blank that I'll be putting up for sale soonish - it does easily sub-minute with M118LR. I also have a Midwest 5.56 carbine barrel that shoots sub-minute with anything decent.

On the other hand, I am in-process with Mike Ross at Criterion right now on an ADM 5.56 barrel that shoots 4 MOA. I also have been reading accounts from others encountering difficulties.

I guess all this is to say that from my observations, Criterion is not the slam-dunk choice it once was.

I can comfortably recommend DSG's match-grade barrels. They are, I believe, a high-end Ballistic Advantage product. My 6.5 Creedmoor is a 5-shot sub-MOA all day, as is my buddy's 308 18".

Thanks for the information, maybe I need to keep looking. Was looking at their M110 profile barrel, but if their quality is been going down lately may not be the choice for me.

I bought a Proof AR-10 barrel last year. 18 inch, full steel, not the CF stuff.

I am very happy with it.

A touch higher than your range, but I like this one...

Or the Proof Steel barrel that Hoser suggested.

Thanks for the suggestions!

Any particular reason to stay away from the CF barrels from proof Hoser?

Cause they are stupid expensive.

Well that is true. I meant from a proformance perspective. I was considering one for weight savings for a hunting AR-10.
