Vector V-93 US parts count? Want to install wood G3 stock.

I plan on changing out the stock on my V-93 with a G3 style wood stock and possibly see if I can mod a wood for end also to fit, since these will not be US made, I'm worried about staying 922R compliant.

Any one know what parts the V-93 has that are US? I'm thinking the stock and for end are US?

Best way to install a G3 style stock?

I have a few HK mags but will also be using Magpul AR PMAGS, but I would like to use the HK if I can stay compliant.
