Headspace Gauges

[Robocop1051]

Anyone got a set of 6.8SPC II gauges laying around?

I'm building a special upper for an old family friend. He's a retired LEO in his 70's, who used to work with my old man, and just likes to blast from a bench all day. He just had 4' of intestines removed due to cancer, so I'm building him a new blaster for when he's recovered enough to go out and play again. I got everything laid out for the upper when I realized, I forgot about checking this out with gauges. 

Im mating a Wilson Combat 18" barrel to a AIM Surplus bolt.

I don't-but will Wilson Combat headspace it for you, if you send them the bolt?...
