So I decided to model a PSE Tac 15 simply because there are barely any bloody crossbows out there. Collected a whole bunch of reference pictures from all across the web. It's quite ridiculous how few proper orthogonal pictures there are of this thing, but I managed to find about 2 or 3 which were extremely good for modelling on.
So I ended up with a whopping 43451 polygons, about 10k of which are in the stock alone. Do whatever you want with it, just remember that it came from Germany.
Grab it here!
