Picatinny hinge for Nerf Smiley

Items needed are as follows: One M3x30 ScrewSix (you could also get away with four but it wouldn't be quite as sturdy) 8mmx2mm magnets ADDITIONAL STEPSYou will most likely need to cut down, or get shorter screws for the part that attaches the rail to the blaster, as I tried to make it as slim as possible. This resulted in the screws being too long and hitting the bolt sled. I believe that I cut mine down about 2mm.
