This was suggested a long time ago known as the Build and Paint Gun. If you wanna check it out, search it up.
Anyway, i'm suggesting we could get the Swiss Army Gun, and remove the extra features (Wand, Bomb, Nuke, Theme, etc.) and give it the model Filipe made. That model looks so epic that I just HAD to suggest this. If you wanna see it, again, I'm too lazy to show it so it's in the Build and Paint Gun topic. Be ready for pure epicness.
EDIT: Never mind about the showing thing. Look down at Shell's post.
Thanks, Shell! .-.
