This is a 3d printed curved foregrip / handstop, this grip can be compatible with keymod or M- Lok systems, providing a secure attachment for almost any airsoft gun. Just let me know which attachment system you require (fittings included). I am also currently working on a 20mm picatinny version.
I have personally been using this design for years and can honestly say it feels great to use.
Be aware, this is 3D printed so layer lines will be visible as seen in photos.
