CVA mountain stalker is the same. I saw a few wood stocks for sale on eBay. Deercreek products has a synthetic camo stock for the bobcat. About 30 bucks.
There's a cva plainsman wood stock for sale on eBay. It looks about the same as the mountain stalker and bobcat.
The guy wants about 70 bucks plus shipping.
It's seems to be in pretty good condition.
