Nerf Rail-mounted Front Ironsight

This is an Ironsight Specifically spaced for use with the Nerf N-Strike Retaliator or Recon, for this Mock Red-dot: https://www.thingiverse.com/thing:2018780

I have printed this, so I know it fits to the rail correctly, and it will certainly be in the right position if used with the Retaliator/Recon front barrel on the Retaliator or recon blasters, or a blaster with an extended top-rail that is at the same level along the whole length, such as a Halo Bulldog (someone try that, it would be so cool).
