So, new to the whole 308 AR world and wound up with a Tactical Ambush barrel. It has a DPMS extension but an AR10 carbine gas tube length. It was labeled as a mid-length and I assumed being a DPMS pattern barrel the gas length would follow suit.
So where do I get an Armalite carbine gas tube? Rainer Arms has been processing my order for over a week and I can't get them on the phone or email and I don't want to pay $17 in shipping for a $14 part from Armalite. I've found rifle length. Could I gut a rifle length down?
