Well the mystery is solved. The bit you sent labeled .073 easily fit in. I measured the bit at .072 so I’m comfortable saying this is a .073 GP...not .069. Barrel is dated 9/17 if anyone is interested....not sure if you can see that in the second pic.
I’ll go ahead and order a tube from you. With the goal of 50/50 suppressed and wanting to be able run xm193 down to Brown Bear what would you recommend size wise? I’m heavily considering the new OSS 7.62 can or low back pressure design like the Dead Air Nomad.
Thanks again!

Once a Rifle, Always a Rifle
The BATFE has made it very clear that once a receiver is built into a rifle, whether by a factory or by you, it is always a rifle and converting it to a pistol is illegal.
OP are you using the upper on the same Colt lower?

I appreciate your concern but as @mistwolf pointed out, I put this on an LMT lower that I bought stripped and built with a LPK.
There is an interesting wrinkle with this rifle though. I had sent the lower back to Colt because it had all types of file and tool marks on it. Colt said it was indeed “out of spec” and sent a new one. I asked if it was a virgin lower or if it was from a rifle. The guy I spoke to said he personally pulled it off the assembly line and it was never assembled into a rifle. I guess I could technically use it but I’ve decided to SBR it as planned. I like the idea of having an SBR and pistol lower.
To the original post, I just received the .069 tube from BRT. I was going to install it this weekend but got distracted with our AC going down. Will have to wait until next week but I will be sure to report the results.
