Early Norincos weren't too bad, but the later (commercial market) production was pretty sloppy.
For an early rifle that hasn't been butchered and Tacticooled-out, it's a reasonable trade (if you really want an SKS).
For a later production Norinco... I'd hang on to the XD.
Something else to consider:
If the parts count hasn't been complied with, in accordance with 18 U.S.C. § 922(r) and 27 C.F.R. 478..... the extra-capacity magazine makes the rifle a 922(r) violator. (Except for the rare chance that it's an original "paratrooper" model; but, then you shouldn't be getting it in trade for an XD, either.
Now, if you can find a beat up, but usable, Russian
SKS... Good trade.
