AIRSOFT GRIP
Foregrip for keymod rail. 2mm spacing is indented into the rifle side to accommodate for the keymod nuts.
Keymod nuts required!!!

UPDATE - May 2nd 2018
It has been brought to my attention that this grip does not follow the keymod spec directly. This is still not a safety concern as the main function of the angle grip is purely to pull the pinky and ring finger away from the rail to keep ones wrist at a more ergonomic angle; not to be used as a whole hand grip. Ensure when used you are gripping the rifle it is mounted on as well as the grip underneath.
Cheers,
Charlie.
