it a good design
but, i missed out 2 small blue bits and when its under 16 bands on power it just blew up when i shot it ;(

I build it and it shoot like 2 feet

use more rubber bands !

this happened with me, i was totally gutted, plz fix

can you make the part list because i am not sure that i will have it. i dont whant to destroy my gun

I like it. It looks futuristic. I'm gonna build it after I finish my homework.

Does it ever jam/ have reliability issues?

No, this gun almost never blocks and the mag doesnt block either !
the only problem you can have is that the pushpin falls apart if you use to much rubber bands but you can shoot very fast without blocking :p
