    Mine, too. What’s the worst that could happen? The only other option, which seem to be to replace the barrel.
    If we have to march off into the next world, let us walk there on the bodies of our enemies.

    A “here, hold my beer and watch this” idea. Why not pull the blade and drill/tap in the slot for a setscrew through the crack? It might be enough to stabilize it and would be hidden by the blade.

    Like this...

    It would likely be less expensive just to unscrew the barrel and screw a new (or used) one on in its place.

    Finding a spare barrel is probably the ideal, but that may take some time to find.

    Yep, I would make a phone call to the factory and see what they have available, and what it would cost to have them do a swap.

    If its truly hairline, I would just keep on keeping on with it.

    Maybe keep an eye on GB for a 629MG parts kit. If GB still offers it, set up an email with certain tags in it so you get an alert.

    I’m not a metallurgist, nor a machinist, but that crack is moving forward, not downward. Take it to a machine shop, and ask them what they think. I suppose a gunsmith’s opinion would be just as valuable, as long as you find a REAL gunsmith.

    Micro tig or laser

    I run a small welding shop and I'd fix that in 20 minutes start to finish. Take it to a skilled tig welder..low heat on pulse with .020 dia tungsten, a little pre and postflow on the argon..could heat paste inside and around the area but probably wouldn't be necessary. I'd groove out the crack with a tungsten carbide burr like at the dentist and fill up the groove with 308. After welding a little touch up with a stone and scotchbrite for a nice brushed finish on the lug. Took almost as much time typing as the whole job. If your really desperate p.m. me I'm in Michigan and you could ship it to a local FFL that I weld for occasionally.
