Vertical Pistol grip for AR

[BigStiCK]

Hey All,
Did a search & couldnt find, so I was wondering if anyone makes a vertical or near 90* pistol grip for the AR platform. I'm talking about the grip on the receiver, not the handguard mounted types. Links?
Thanks

I don't know why you are so interested in a 90 degree grip, but the Stark Industries grip seems to most match your request. I've never used one, I'm not interested in them, but here's a thread about them. There are other threads about them, just search for "Stark grip".

HK makes them for their models too.

This might be the closest thing to vertical

I also found that the Magpul grip with different straps got me a little more vertical.

I just had hand and arm surgery so hopefully I won't have to be thinking about vertical grips anymore:D

I thought Hk uses a Tango Down grip?
