This is the only section of the thread that appears to be stripped. Its only about 2-3mm. All other threads are okay. Was this from over tightening I assume? If so, that doesn't make sense since more threads should be stripped right?
Am I okay to use this buffer tube or should I get a new one? The castle nut is on pretty tight so Im thinking it would be fine?

I appreciate the responses. Thanks

It just looks like typical aluminum on steel galling. There might have been a small piece of grit or something in there to cause it. I think it would be fine but you may have trouble if you ever take it back apart. I don't know if it's customary but I allways lube threads when assembling anything aluminum.

Okay cool. Yeah I didn't lube it or anything prior... I was afraid to loosen the nut to examine it more because maybe it wouldnt go back on. But I'll leave it be

Or was it from the wrench tab hitting it?

The threads should always be lubed, all torque values are given for "wet" tightening. Torquing dry gives false reading due to friction.

This goes for the barrel nut also.

Buffer tube doesn't cost much. I doubt there galling on the receiver threads but it's best to check.
