That counter monkey was an idiot. Colt makes good rifles, but so do a lot of other manufacturers. So long as you avoid Hesse, Blackthone, Vulcan, Olympic, you should be fine.
Commercial tubes were made thicker because the 6061 is softer. The reality is anything that will damage a 1.17" 6061 tube will most likely also damage a 1.15" 7075 tube.
The thing you have to watch for when buying is to make sure that the mil spec diameter tube you get is 7075 and not 6061; There are several manufacturers that make 6061 mil spec diameter tubes, which are weaker than a commercial tube. Would probably be fine for 99% of use, but why buy the tube made of weaker and thinnner metal?
I run commercial tubes on all of my ARs because both of my earlier production Armalite rifles had them, and it was more economical to stick with commercial pattern for stock interchangeability between rifles. I'm pretty rough with them, never had a problem.
Except for the difference in material (mil-spec is 7075-T6 vs 6061-T6) and the inferior method of threading that doesn't leave a full profile thread in the commercial tube. For a range plinker, you're right, there is no difference. For a rifle that is going to get beat on, there's a difference. There are also several stocks that are only available in a mil-spec diameter. I've yet to see a quality stock that was only available in commercial diameter.
Really??? Do you care to back that statement up with facts? I'd like to see the first example in history of a commercial tube being proven as inferior to a milspec one, even considering the type of metal.
