DIY Nerf H.A.M.P.




Here is a video I made showing you how to make a H.A.M.P. (High Air pressure Manual Pump) out of PVC. This gun will shoot Nerf darts, slugs, and stefans up to 100 feet. This is a great gun to use at Nerf wars or just in your back yard shooting targets.

    Very cool!

    Do you have a video showing it in action? That would be fun to see how far it shoots.
