Well, I guess that is one way of doing it. Wouldn't you rather spend hours and hours sanding fiberglass and bondo? lol!
Looks amazing! I need to figure out the laser cutter at my school.
Now that's a BR. All you need now is to bondo the edges a bit to make it uniform, add a barrel and a scope and you've got one bad ass weapon. Just be sure not to go through any metal detectors with that on you. xD
