Your stock is also repaired with threaded brass pins on the woods right rail along with the crack behind the recoil plate.
Look closely at the fit between your recoil plate to the rear of the receiver.......not to snug.
If replacing the stock I'd strongly advise putting a better fitting recoil plate on it. They do wear out. Doing so will improve accuracy.
BTW..... your stock shows the cut out for the M2 selector lever on the leftside.
With your carbine being a import it really isn't worth putting the $$ into a proper SG stock for it.
If your just shooting and don't want to tie a lot of $$ in it.....I would also pick up a solid shooter stock for it. Any USGI stock or even a ItalianFAT stock will properly fit. With little out of pocket cost.

P.S. make sure any replacement stock you buy has the recoil plate screw escutheon nut still installed. It can be a bear to install one and get the correct fit.
