I made this 3D print based on the sight for the Destiny 2 weapon, Vigilance Wing. I think it looks cool, so I made it. There is a little groove in case you wish to add a transparent plastic sheet and draw an aiming reticle. There is quite a bit of clearance between the sight and the rail because I made this for the Nerf Rival blaster and the rail continues right to the edge of the charging part.

Print it in an orientation that strengthens the horizontal axis of the "dog-shaped" reticle sides.

Paint it gold to match the color of Vigilance Wing.

I downloaded a picture of Vigilance Wing and traced the outline into Fusion 360. The Nerf rail was taken from "Nerf Sight" by keylitho. I just cut off their sight using boolean and replaced it with the Vigilance Wing sight.
