Uh, that's not a stock 10/22. Shooter changed the stock, the barrel, and
probably the receiver.

The receiver is the part with the serial number on it. Duh

I am also not sure much but the stock was changed and that is common
with 10/22s. They are sort of like ARs. You buy the part with the
serial number and make whatever kind of gun you want.
The 10/22 may be the best selling .22 out there over the 50 years it
has been around.
