OP here, After some more digging, Wilson Combat lists the Intermediate Gas system on a 14.7" inch barrel. I'd imagine that's about as short as possible for that system, otherwise WC wouldn't make it. Guess I'll just go with a 13.7" mid-length. Oh well.

Well I won't be purchasing a Noveske barrel. My pockets aren't that deep. Ranier Arms has a 16" intermediate with presumably the same dimensions as far as port placement. If guys can get dissipators to run in 5.56, why not the intermediate at 13.7, in .308?

My main concern, which is the same as anyone else messing with gas systems, is dwell time. From doing some digging, it seems the Noveske intermediate system has the port 11.5" from the face of the receiver. Knowing that .308 has much more gas available and a slower overall velocity, theoretically there should be more leeway with having ~2.5" of barrel past the gas port. Does this hold water?

First post here, and really my first foray into the world of 308 ARs. Has anyone ever run an intermediate, not mid-length, on a 13.7"-14" barrel unsuppressed?
