This is a very tight fitting Nerf scope attachment usable on N-Strike rails, and clicks in with quite a bit of force needed to pull out. (Depends on the Nerf Blaster). This attachment is only designed for the top rails as for some reason Nerf made top/bottom slightly different, but use at your own will. Please note once again, this only works on N-Strike rails commonly found on most Nerf blasters. If your unsure if your Nerf blaster has one search it up and make sure it's N-Strike! Note this does not help you aim, just for cosmetics.
