Quoted:
They are not cast, but forged. Every 601 receiver I've seen has been smooth. Are you sure it is a 601?
I guess I'm not sure, I purchased it as a 601. It has all the features of a 601 'cept the flashing inside the carry handle looks 'removed'.
The pivot hole is rebated.
There are no rear sight marking on the right rear of the carry handle.
The rear sight is a 601, not a repro.
There are no forging marks in the recess under the rear sight.
'C' in a square over a triangle up front.
Ejection port door is correct.
The hole for the ejection port door spring is correct.
The off set profile under the ejection port is correct.
It appears slightly pitted and refinish in what I'll call the matte black, dont appear to be recent.
It was the inside the handle that got me thinking........
