These are my 2 versions of the Nerf Rival Takedown Grip by haphazardlynamed (https://www.thingiverse.com/thing:4418085). One version has only the grip, while the other version includes a stock attachment point that is compatible with any N-Strike style stock.

Haphazardlynamed’s dimensions were perfect, but I wanted to change out the grip, as well as add a stock attachment point. Both grips use the screws that are taken from the stock grip. The styling is subjective, so I included the .step files for those interested in making improvements, adjustments, or any custom stylings they desire.

Enjoy!
