Handstops other than KAC?

I got this one from deliberate dynamics, but I have seen some other ones in pictures. Are most of these custom or are other companies making them. I want to get one in FDE if possible, but haven’t see them yet. And the only plastics ones I have seen are REAL cheap looking.

GearSector.com makes them.
Black is here and FDE is coming.

Black no FDE

the edges on the first one look like they would hurt your hands after a while.

I couldnt find the hand stop that I wanted/needed, so I had mine made from an HK “K” grip and a tango down rail cover. the HK grip was filed down and then the TD rail cover was glued to the unside of the hk grip, to use as an attachment point.

GearSector looks like the nicest, though the AFG can be used in the same capacity with longer handguards.

This would be my vote.
