Change of plans. The Faxon barrel has a larger gas port than what I wanted and I don't want to deal with overgassing if I don't have to, so I contacted Brownells and dropped that from the order. Found a barrel that Ballistic Advantage has out now, classic series 10.3" with chrome lining and a Crane spec 0.070" gas port for $160, free shipping and no tax. For an additional $40, I added one of their gas blocks and they will pin it to the barrel for that price. I feel better now.Alright you hooligans, looks like I'm finally joining the Law Tactical folding AR pistol club. Placed an order for the folder and a Faxon 10.5" barrel to convert my existing 12.5" AR to backpack capable duty.
