As for your gun, let's figure out what you've got before you go replacing anything. If it is a VN bringback, it may be one of the big three (NVA, E. German, N. Korean) and worth north of $1k. In that case it would be better to try and fix the stock than it would be to replace it. Even a run of the mill Chinese bring back is worth north of $600, though with those, papers and condition are key.
