    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!

    Tig welding uses the least amount of heat but I would probably go with hard silver solder or ( silver Braze).
    Gas blocks are not that expencive so you could look into getting another one.
    Would warrenty be viable?
    F.K.
    P.S. Brownells has Gas blocks from $ 35.00-$100

    Sorry I was thinking AR's
    Tig welding is probably your best bet.

    You could also use a mig welder and do just a tiny bit at a time, letting the barrel cool between steps. Be sure to use a clamp or make a makeshift jig so it's positioning is perfect.

    Heat vrs. distortion

    There are low temp Silver soldiers that might work in your situation. Any heat to the end of a barrel will distort the acuracy of said barrel. In over 30 yrs. in the machineshop bidness the barrel will bend when heat is applied. The closer to the reciever or the end of the barrel in the sight area isn't as bad. If you don't believe this go to a machine shop and ask for a demo. There are ways to straighten the barrel but it is a 100 to 1 shot that it will be accurate. Some times it is just better to bury the dead and replace the barrel. Good Luck And Good Shooting!!!:)
