Help on what to do??

[jworm1420]

So I just picked up my S&W Thompson center LRR 308. But my muzzle brake isn’t on properly. The ports on the brake are not set at 9 and 3 o’clock. They are at 10 and 4. I sent TC an email about it waiting on reply. Why do u experienced guys think about this and what should I do. I added some pics but it is kinda hard to tell the brake isn’t right. Hopefully u guys can see it.

Doubt the crush washer has enough give left to get timed right, I'd back it off, throw a new crush washer on there, then time it myself. It's inconvenient but will be a way quicker option than to see if S&W will get you a return label for it

Get a jam nut put it back on.

Ok guys. U guys have to explain what u mean by timing it. This is new territory for me and I don’t want to screw this up. I prefer for warranty purposes and such to send it in and have it done professionally but I also agree I don’t want to deal with waiting sending it back and waiting to get it back. So if u would please explain what that means. From what I am understanding I just need to screw off the brake put on new crush washer and then screw it back on tight to where the ports are at 9 and 3. Is it that easy?

With a jam nut you can do that very easy. Yes 9 and 3 is how its supposed to be. Doesn't have to be super perfect you can eyeball it. Jam nut you put on first then put the brake on screw it in until it stops. If it isn't the right position screw it backward until it is, then tighten up the jam nut against the brake and you are done.

I have some very thin shims as well but no idea where I bought them.

ok thank you for the easy run down on how to do it. My only other questions is what method to use without damaging the barrel/brake when holding And getting a tool on the brake to tighten it. Suggestions??? Thanks.

I put my firearm in a vise that has carpet on it so it wont scratch the firearm. Then I get a heavy duty screwdriver put a few layers of masking or electrical tape around it. Then stick it through the brakes holes and twist them off, or on.

The OP's on the right track. Let T/C take care of this. Could be more than just a mis-clocked brake wrong.

It's a new gun, it should be right. Hopefully they'll make it right, and then some for his trouble.
