The FAB Defense Gen-II Vertical Foregrip w/ Integrated Adjustable QR Bipod does not mount directly to M-LOK rail systems. You would need to use an M-LOK to picatinny adapter rail, like the one found by using the link below:

The manufacturer dose not state that this can hold a flashlight.
This should be tight and should not have play.
All FAB Defense products are made in Israel.
This would be considered a vertical foregrip, so it is not allowed on a pistol.
It will depend on the rail, this requires specific spacing of the cross-slots, so if they aren't spaced correctly it will not fit. This is the advantage of picatinny, it has a set standard so the cross-slots are always correctly spaced.
Yes as long as you have a picatinny rail on the bottom.
From what I can tell based on the part numbers you provided is that one model is the standard rail mount while the other is the "QR" quick release model.
Unfortunately we do not sell small replacement pieces for these FAB Defense products. FAB Defense is the only source for these parts. You may need to fabricate your own part to replace it if FAB Defense cannot sell it to you.
