Handgrip with slight angle like a pistol grip does. - FAB Defense Vertical Foregrip

While this is not my first forearm grip, it is the correct one for my hand.

I've had vertical grips, other angle grips but they just were not the correct ergonomic angle of a hand.
This is why a pistol grip has its angle to fit your hand in a natural angle.

This grip actually has 4 finger groves and the backstrap fills the palm of your hand.
I may or may not put a pachmayr grip on it like I have on the AR pistol grip

It says it has a compartment but It does not open easy, so leave it.
It does have a quick release for some reason and it also has a standard picatinny screw
