So I picked up a polish tantal 5.45 for a good price, but low and behold..... it keyholes. I have a new chrome lined correct barrel for it, but do not have the tooling or the knowhow to do a rebarrel. Is there anybody in central NC that would do it?
Check it for muzzle damage first. May take a recrown or even a slight counterbore. I repaired a minute of 50 gallon barrel SKS once with a 1 inch counterbore.
