So I just got my new McGowen barrel. I ordered a .25 recoil lug from midway to put on when I swapped barrels. I was just trying to install and headspace my barrel today, turns out Mcgowen didn't cut enough threads on my barrel!! I screw the barrel nut all the way down till it stops. Once there I threaded on and it stops on the recoil lug before the bolt face. So I took the recoil lug off and screwed on the barrel with the nut still on until it contacted the bolt face. I took a micrometer and measured the space -- 0.11" not even enough for a stock recoil lug!! I can't believe it. I have heard some horror stories about them and their customer service (which I didn't find until my barrel was well on its way here), so I would rather not send it back.

BTW I know for sure the nut is ALL the way on. I have checked it about 30 times and even tried tapping it with a hammer gently to see if a burr or something was stopping it... trust me it is all the way down.

So my question is... now what?
