If you ever find the article send it over to me, id like to check it out.

If you are going to run a gun this hard, it would also be wise to run a free float hand guard, it would help prevent any additional stress on the barrel causing sagging or warping from things like vertical grips.

It probably wouldn't hurt to get a heavy barrel and get some fluting to reduce weight and increase surface area for cooling too.
