folding iron sights for nerf foam blasters

folding rear sight with different apertures. no supports needed. I used a small ziptie melted on both ends on the rear sight to connect it. you can also use a cut hanger and super glue. snaps up and snaps down. front post may be shortened or heightened per your blaster max and min range.

if its too loose on your rails, just use a heat gun or lighter to tighten down the tolerances. have fun yall.
