Nerf picatinny adapter, adjustable angle and height

thingiverse

Picatinny adapter for Nerf guns. Use red dots and scopes with your blasters! This design is a clamp-style - it's easy to put on and take off the gun. No glue or tight tolerances needed. There is a built in angle of 0.7 degrees (42 MOA) to compensate for the bullet drop. Make sure you install it in the correct orientation (the top of the picatinny should be pointed slightly down the range, bolts should go from the left side of the gun). There are 3 variations of height. Most of the guns will work fine with the low-profile rail, however some guns (ie Helios) and some red-dots require a riser. Fusion 360 model is attached for your customization. There are 2 user parameters - Rail_angle and Riser_height. If you set the Riser_height to less than 10mm, it's recommended to supress Hole_in_the_middle feature. You need 2x M3x25mm screws and a 2.5mm drill bit for asssembly. Drill the holes in the clamp to 2.5mm, put everything on a gun and screw in the screws. The "base" part is printed with support in it's natural orientation. Only bottom of the nerf rail should be supported. Everything is 100% infill. I printed in PETG and it holds up well to the abuse. Enjoy!
