I have a Universal M-1 Carbine, and the gas block has separated from the barrel - it blew off while firing a standard, commercial .30 cal. round (not a handload.)
My question: Can the gas block be re-welded to the underside of the barrel, without the barrel being warped by the heat of welding? If so, WHAT TYPE of welding should be used - MIG, TIG, stick?
Thank you in advance for any assistance you can provide!
