I had a muzzle brake pinned and welded and don't think the smith did it right. It's timed right, and pinned, but is slightly loose.

I don't mind it if its ok. But I thought there should be no movement at all?

I feel like a noob. Is it right or not.

final update: So after reading my post the nice folks at mastodon offered to fix the other shops mistake. Nick took the time out of his day to fix my issue. He had me take pictures of how the other shop did not drill down enough on the barrel and of course showed me how to use a crush washer. It was a very amusing time at the shop. If you guys ever need anything I can say go nowhere else.

It shouldn't move, have him fix it.

:unknw: If you don't get an answer here I'd PM PK90 or Shane45.

It looks like the problem is in the crush washer. Normally that jams on the muzzle device, and no pressure is put on the pin until someone tries to remove it.

The muzzle breaks are actually under quite a bit of stress, remember that all those gasses push against it enough to move the entire rifle. With that much play it will eventually break the pin and weld. Get it fixed,

are you sure he didn't do that on purpose thinking it's going to add an extra twist on the bullet??? :unknw: okay, I joke, I joke. I'd ask for it to be fixed.

This. It probably should have been tightened one more turn before pinning.

There should be absolutely no play with the muzzle device at all. What would happen if it moves enough that the bullet grazes it as its coming out of the barrel? Not good. Please tell us who did this for you.

there shouldn't be enough play for contact but it will break.

Exactly what Lalo said its the main concern

It was done wrong. THis looks like it was done by someone who doesn't grasp the concept of a crush washer and said I don't want to torque it down that hard.

As everyone said. Definitely done wrong. You'll be amazed how much you can compress that crush washer. I've done a whole 360 degree of turn on one and have heard it can go a bit more. The washer's gotta get crushed before pinning. You're not going to strip the thread.

 

Send it back and get it done correctly or get your money back and go somewhere else. This is a ridiculous error on the smith.

Still from your video:

 

That's a large gap; the smith should have went another full turn with your brake.

 

Nice screen cap. That's exactly it. That washer's loose as a goose. We like'm TIGHT! I'd be pissed if I had to wait a while for a pin job to have that returned the way it was.

 

I think the OP got the point. Git'r done!

so the ffl was nice and worked with me, told me with the crush washer with the brake would not time right and to keep the brake on right and tight it would need either a bigger crush washer or some peel washers.

he is ordering peel washers and will fix it for me next week.

He's going old school with the peel washers - that's fine. Good to see that your smith is taking care of the problem.

 

Edit: Just noticed the timing comment. I disagree that it won't time right as there's definitely enough crush left for at least a full turn.

Yeah, glad to hear he's making right. I don't think he knows what he's talking about either. When I was hand tightening a brake, it clocked exactly to position when the washer started giving resistance. If I didn't turn it the full 360, I wouldn't have believed it. Some smiths would even pre-press the washer in a vise before installing it. Just seems like a pretty simple job made complicated.

So, who did the initial work?

 

...and post the pics of the barrel your took.
