I’m not a gunsmith, nor do I play one on TV. The last time I hired a gunsmith to work on my AR he removed the compensator in order to install a new gas block and when he re-attached the compensator it was not put on correctly. It’s canted slightly to the right. In order to get it straightened out I called another smith and asked him how much it would be, and he said it depends on whether there is a problem with the threading. It’s the original compensator and the original barrel, I said; why not just take a wrench and give it an eighth of a turn counterclockwise and be done with it? No, he said, there might be some problem with the threading (that didn’t make sense to me) so he might have to cut the barrel down and re-thread it. Is this guy BSing me or is that a legitimate concern?
Thanks in advance.
Most likely the crush washer has been compressed and won’t let it like back up with correct torque value. If you are using a comp/brake that needs timing you will need shims. If it is an a2, a new crush washer should work fine
Post pics, and try to get some detail, that should help us.
If the whole thing is mashing up the threads, you’ll need to cut/rethread I believe. Make the other guy pay.
Inspect the gas block as well. If he can’t install a muzzle device, I can’t imagine how the gas block turned out.
Dude, what? No. The threads are fine.
The crush washer got compressed and that’s why it is overclocked right now. That other guy is an idiot.
You can do it yourself with the rifle in your lap, a new crush washer, and a crescent wrench.
Guess I missed the “slightly” part. I was picturing a heavy cant, disregard my previous post-sorry.
Thanks for your help folks. I took another look and it turned out that it needed a slight turn clockwise instead of counterclockwise, meaning that the last guy hadn’t torqued it far enough. I was able to resolve it with a crescent wrench and a judicious application of elbow grease, and no new washer was needed.
Glad you’re straight again. Don’t go back to that guy.
It’s easy to under/over clock a muzzle device. It’s also easy to fix. No need for anyone to over-react and call anyone an idiot. The second gunsmith is probably just inexperienced and being overly cautious. As you can see, it was a simple fix and everything went well- even if a Crescent wrench was used
