I purchased this barrel last spring when the panic was full blown and barrel's hard to find. It has sat in my closet in original package until now, I decided to build an AR. I never noticed until I went to screw the flashider on, the threads are damaged. I have no idea how it happened, if it was that way when I received it, or if someone in my house dropped it. The maker said to send it back and they would replace it, but now I cant find the invoice.
It's only the first couple of threads, I'm wondering if it would be possible to fix rather than go through the hassle of sending it back. Does anyone have experience with fixing damaged threads? Is there a way to remove/file away the first couple threads to get the flashider started? Advice appreciated.

Thanks guys for the replies. When I talked to the supplier he said send it back with the invoice, I said no problem thinking I had it. Now, I cant find it and the email confirmation is long deleted, so I just figured if it was an easy fix, I would just handle it myself. I havent asked him about not having my invoice yet, so I dont know if it's that big of a problem. I'm sure they have the original.
I was honest with the guy, I told him I'm pretty positive It didnt get damaged from me, but being that It was last spring that I received it and I'm just now finding the problem, I feel a little bad about it. It could have been UPS who dropped it, but it's my fault for not inspecting it better at the time. |

Quoted:
I'd be worried about the crown as well. If it were mine and I couldn't return it, I'd take a few passes at it with a crowning tool. Should remove enough to get down to good threads and ensure you've got a consistent crown. http://www.blindhogg.com/pics/tool16.jpg This. Or take it to a gunsmith or machine shop who can. Also see if your email acct has a "trash" folder of deleted emails, mine does |
| The crown is the edge right at where the rifling meets the muzzle. The threads are relatively nowhere near close to the crown so I don't understand the talk about the crown being damaged. Get a 1 / 2 x 28 die and chase the threads. Done. Now, if you can see physical damage at the junction of where the rifling meets the face of the muzzle then that is another story, but just those threads being boogered up would not concern me in the least. I'd either chase the threads or take it to a shop that has the die and let them do it but I really do not see that big a deal here. |
absoulutely not a problem to fix.......shoot me an email to [email protected] ............it'll take longer to set up in the 4 jaw chuck and indicate the center line of the bore than it will to actually machine it.....
