Sping loaded Tip off Optice mount for Sub 2000

I actually would like something similar to this, however since I have a Gen 2, I'd like it to mount to the side of the forend and tip on and lock down with a QD RTZ mount.  I can always add a M lok Pic rail to the side to mount it, but I feel that if it also had a QD mount to secure it to the forend it would be much more stable.  But still allowing it to fold to the side for folding the rifle.
