I bought (and have barely gotten to use) a colt competition pro 18 about 5 years back. What happened to this department or gentleman who was making these? What about the adjustable gas system?
I don't know what happened to them for certain but it was probably multi-faceted like a lot of things are so I won't speculate. I think the guy that owned Bold Ideas/Colt Competition started another business named Ox Manufacturing (Ox Mfg), and this looks like it could be the same gas block that was previously used on the Colt Competitions.
Bold Ideas/Colt Competition only licensed to use the Colt name on the rifles, I don't think there was really anything on the rifle that was actually from Colt.
