Pof usa universal bolt catch - POF USA Universal Bolt Catch Black Anodized 00667P

This is a very good bolt catch. The extra room on the bottom for your finger is perfectly sized. And unlike the Geissele bolt catch, this one doesn't inhibit accessing the trigger pins when it is installed. This POF bolt catch comes just as shown, with no additional attachment hardware. It is a black phosphate finish (since it is steel), not black anodized like the description says.
