During the ban I would pin and weld, I am not that crazy about hitting the muzzle of my bbl with 1500* flames, until it turns red/orange. To me it just seems wrong on so many levels. I was also hedging my bets for when the ban finally went away, in Sept. it was real easy to find the weld, drill it and the pin out, unscrew F'ed up brake then add normal supressor to undamaged muzzle.
Good Luck,
