I decided to restart the BMP-11/9mm build. The new scope is to just finish it for myself, and not to try to make a selling product. I added it to the weaponsguild build challenge here:

This is a bit ugly. The large ABS parts always seem to warp during printing. Even from this crude shape, I think I have some finally design tweaks I’m going to make and start printing a newer version 9. It will have a lowered ejection port, Fatter shell in general for thicker sides, wider foregrip, and a smoothed magwell.
