Looks to be 5. I had to attach it to a Picatinny rail segment because my handguard is all mlok, and I would recommend cranking down on the hex screw if you go that route because it seemed loose when it felt like I had tightened it quite a bit. I went ahead and cranked it down a bit more, and now it’s solid, and opening up a can of man on it hasn’t affected the grip or its ability to retain full magazines. Do note that it is angled, so other attachments that may be in close proximity to the foregrip may need to be spaced a little further away to make room for your hand and the path of incoming/outgoing magazines.
