Foregrip Long Version Vertical Grip

It feels nice, however I am unsure as to how you'd mount a tapeswitch for it. My SR07 does not fit the slot it has. It also does not fit a KAC M4 RAS handguard, as the inner edge collides with the rounded "corners" (between the bottom and side rails) of the handguard. With a file, I could definitely make it work, so it's not all bad.
