Cleaning up stripped threading on buffer tubes?

[Mosinowner]

Can it be done? Would I be better to just cut the buffer tube so I could get the castle nut off? I cannot move the castle nut past the stripped threads because it gets stuck. Suggestions

how on earth did you strip threads on a buffer tube? so you have the buffer tube off the rifle but you can't get the castle nut off the tube? is that correct?

It isn't going to hurt to try it. Use a jewelers file to file away the metal that is pushed out of place. I constantly have to chase threads on stuff that gets stripped. You might also be able to find someone local to you that has the correct die to chase the threads.

Yes. The way I stripped it is the crappy stock wrench I have been using

You know how when you were 13 you used to beat the snot out of your friends with Hot Wheels tracks? Well, he's got gun parts instead of Hot Wheels.

Yep

I'd think if you had a decent way to apply torque to the buffer tube, then wrench that castle nut through the stripped part by brute force, it would very likely straighten those threads out enough to use the thing. The buffer tube is aluminum, the castle nut steel. Not sure I want to know how you boogered them up that bad in the first place.

It was the crappy stockwrench from aimsports. Also there was user error involved

Well, now everyone has a new sig line.

Local hardware will have a tool called a thread file. It usually has 8 different pitches. Four on each end. Looks like this. Minus rust.

Oh that's sweet. I've never heard of that. I'm looking into it.

So this could be found at home depot? Also would it work for this?

If I recall correctly AR lower is 1 and 3/16 x 16 threads per inch. If you can run nut forward to get at gobbered threads I don't see why it wouldn't. After thread clean-up ,by what ever method, be sure to use a good lube (never seez) before trying to back off nut. Steel and aluminum don't play well together. Will gall at the slightest chance. Explains anodizing. Sorry, maybe Home Depot but more likely something like a Tractor Supply or similar.

So I won't be able to use the buffer tube again? Anyone recommend a good cheap one?

Pick one or the other,I don't think you can have both.

For thread file go to Whole Sale Tool on Hanna Ave just off of 31/East street in the south sife of Indianapolis. They will have it and a lot more "man toys".

That might be a bit of a trip for someone living in Texas without a driver's license.
