Eh, I have a few more designs on another computer of mine (a laptop that got cracker jacked and broken.) but here's what I can actually post. This may/may not be updated xP. Feel free to criticize. I'm sure some shit's wrong somewhere.
I know, that front portion of the reciever looks pretty jacked, I had to 'meld' two parts together to get somewhat close to what I was looking for. I'm crap at photoshop/pixeling/pixel colouring asdf, so I had to stick with it. Couldn't find anything majorly awesome to cover it without making the weapon look like total crap. Again, feel free to criticize xP.
