Muzzel break blew off on the first shot!

[Clayne B]

Just got the 7mm back from the gun smith. Had him thread and install a muzzle break. First shot the thing blew off the front and went 115 yards! Looking at it there was no baffle strike and the bullet was on target. i think it was the blast that popped it off. the threads look like JUNK. How would you go about dealing with the gunsmith on this issue?

Thank you

WOW! Glad your OK. I think it's time for a new gunsmith.

If it's a workmanship issue, he should fix it for free IMHO. Good luck!

Yikes! It almost sounds like he forgot to bore it out to clearance, but you said no internal damage? Only thing to do is take it back to him and show him the barrel and brake. I think they are supposed to have around .020" clearance?.......Rich

Got any pictures Id like to see it

In this picture I can slide the muzzel break on with out threading it on. just slips on down to here...




this is how far it slips on easily

The threads inside the brake look a lot better than the threads on the barrel! Is that thread locker on the barrel threads or rust? Could the braek possibly have been cross threaded on the barrel? They should spin on easily........Rich

Its not rust, I do not know what it is. the threads are not cut very deep at all, and there are little steps, and it looks like it tapers...
