I have the Faxon 308 16" Big Gunner barrel, mid-gas, and I'm using the Armalite AR-10 carbine gas tube with it, no problems. I like the little bit of extra length it provides the gas key engagement. I'm very pleased with it, and surprised that it weighs less than my 14.5" 308 barrels.
I also have the Faxon 20" fluted 308 heavy barrel, rifle gas, and I'm using the Armalite AR-10 rifle gas tube with that one, same reasoning. I have both the 20" fluted heavy, earlier design, and also the later 20" fluted heavy match version.
I also have the Faxon 20" medium tapered 308 barrel, not the Gunner, that one is also rifle-gas, and using the Armalite AR-10 rifle gas tube also.
I get the Armalite gas tubes from either Armalite or Fulton.
