Yeah I second that!!!
Full size guns are so difficult to get hold of without paying a fat wedge for them!!!
Great work Butterbean! 
I love threads like this - they're very encouraging to those of us who want to build as much as they can from scratch!
Couple of questions:
1. What did you use for cooling vanes on the barrel?
2. Do you have any pics of the build process?
3. Can we see the blaster from the other side?
Well done brother!!! :cheers
