It's a 3mil /26\ . Not matching. At some point in time the Bolt and Bolt carrier were replaced.
No Sorry, I don't have the stock that came with it.
The magazine was rusted. One spot was pretty bad with major pitting.
So I disassemble the mag, stripped it down to bare metal and Rust Blued it using
Mark Lee's Express Blue #1.
The Gas tube is a replacement from a de-milled gun. I still have the gas tube that
came with it. It looks good but it's one of the 2 piece types. I wanted the early type
on mine and switch them out.
