You want to be sure that the guy threading the barrels knows his stuff. If the can is canted in any way, the bullet can impact the can and ruin it.
Personally, I'd go with a factory threaded barrel, or someone that does barrels for a living like Green Mountain, Shilen etc. Having Joe $hit do the threading if he's never done it before can ruin a good thing. Just sayin', cause the pain and expense of getting the stamp is ruined if the can is ruined with the first shot.
