I was in a little bit of a Nerf kick 7 years ago. Mostly buying them and customizing them to either shoot further or look cool. One thing I have learned with them is no matter if it's the shortest Nerf gun to the longest Nerf gun they'll shoot about the same distance when you buy them at the store. I think it's a liability thing with nerf is they can't go over a certain feet per second.
Lot of aftermarket stuff for them though these days
