Nerf Apollo Picatinny lower rail

thingiverse

The Nerf Rival Apollo is a solid springer that outshines its counterpart, the Helios. If you're on the market for a new blaster and don't already have an Apollo, it's worth considering the Helios instead. The Helios boasts all the positives of the Apollo while offering several key improvements. A trapezoidal orange piece in front of the finger guard is merely decorative, giving way to a functional picatinny rail that allows for easy attachment of a swiveling fore-grip.
