dalelerah made and tested a working model: [https://www.thingiverse.com/thing:6377480](https://www.thingiverse.com/thing:6377480)

Remix of AR-15 Grip by mr2quik

added features:

• mounting screw hole and channel
• fire selector detent hole
• slightly widened the channel that mates with the lower receiver

I haven't tested the model yet. Will update once the fitment of the holes has been fine tuned.
