Well did some shooting on friday, finaly had time to break it down and clean everything today.

I found the weld had broken on the bottom of the muzle brake. Now I have to reweld it. One problem I have is that I dont want to do it in correctly. Should I take it to a smith to reweld it? I do know how to weld and all that, but Never had done it on a firearm. What could go wrong with just tacking it back into place. It has a spring loaded pin holding it on top, and the weld on the bottom that I can line the crack back up on and tack it.

Fair enough. Originally they were not welded, think it is a thing to make them compliant in states like CA.

If it wobbles do you have it tightened down enough? I is a left hand thread and if tightened down all the way should not move. Something worth checking.

You can retack it, but you need to use a TIG setup so that you can control the heat. Also, using a heat-sink would also help. You just want to make sure that you don't get the barrel too hot when welding and screw up the heat treat...

I have a foot peddle controlled miller tig welder at work that I am going to use. I would love a suppressor on an m4. Not really wanting to muffle the psl. Besides if I end up moving to the PRK I would be in hot water lol

I'm jealous. I'd love to have access to one of those bad boys. Haven't had one that nice since school...
