Seeing a lot of these on the interwebz for cheap lately. I suspect Bold Ideas Texas has liquidated their inventory, and were seeing it trickle down to Gunbroker etc.
I thinking of picking up a bare barrel to finish up a parts bin build.
The profile is sensible, the price is right.
The ones im seeing are rollmarked "5.56 NATO 1/7 C P" or "5.56 NATO 1/7 C"
So what Im wondering is
1. Did Colt make the barrels in house for Expanse/Colt Competition? Or were the barrels sourced by Bold Ideas?
2. What does the "P" rollmark mean?
3. Can I expect a correct 5.56 chamber on an Expanse barrel?
4. Can I expect a .063 port on an Expanse barrel?
5. I am aware the Expanse was not chrome lined. But what grade steel was used?
