I’ll tell you LEGO gun replicas are awesome on their own, but when you combine that with the fact that these awesome gun replicas actually shoot I get all tingly inside.
These guns don’t shoot real bullets mind you, they shoot rubber bands.
Created by PrototypeNo97, these guns make prolific use of rubber bands in their build as well for various things. All I can say is that these guns are all really cool despite the fact that they have little velocity behind their shots. You need to be a LEGO engineer to make one of these things. (Or you need to buy this book).
My favorite is the M249 Para, which is a wicked looking design on its own. I have no idea how they managed to pull the construction off, but Proto could sell these replicas for some coin if he were so inclined. Check out all the vids to see them in action.
