Barrel reproofing
Hi all, considering purchasing the linked 10/22 at auction - but it's a bit of an oddity.
It's serial links it to being a model 01117 - 10/22, Blued, 18.5" barrel
But this one is silver/stainless (or perhaps bead blasted receiver?), with a black trigger, rail and blued barrel.
The barrel is also 16" - with a dovetail for the rear sight, and no front sight. The barrel behind the threads also has a little lip.
The auction house says there are no proofing marks near the muzzle, just what seems the be the original, and no extra proof marks by the breach - but to me this appears to be a shortened and re-threaded barrel.
How do I check this? And a side note, what would the consequences be if this is an unproofed barrel?
Many thanks
