Nerf Blaster M16-Style Picatinny Carry Handle Sight

M16-style picatinny mount carry handle* / rear sight with elevation adjustment. Hardware required: 1x M3 heat-set insert (4.5mm diameter x 6mm) for adjustment wheel 1x M3 x 25mm screw 2x M3 x 10mm screws (to stabilize sight when elevation is extended) 1x M3 nut 2x M4 x 30mm screws (ideally around 27mm, cut them down a bit if you want) 2x M4 nuts Print 2x each of block1 and block2, 100% solid for strength Thread the 2 M3x10 screws directly into the outer holes in the top sight block. They should slide freely in the holes in the main body (but a bit of friction is good.) Screw in the M3x25mm screw and nut tightly. Insert the wheel with the threaded insert side up, and assemble. Pick a peep sight aperture size and slot it in, glue if needed. Works well with something like DuckyIndustries' Ducky Iron Sights front sight I'll try to add windage adjustment some day Maybe not recommended to actually carry the blaster with! :)
