They are precision machined out of 6061 aluminum, given a satin finish, and then black anodized. Each mount includes a 2.5MM allen wrench and a 4mm x 0.7 screw and washer to attach it to your carry handle. Two 7/16 long 6-32 screws are also included for mounting a Trijicon RMR, along with two special 3/8 long 6-32 T10 torx screws for the Holosun 407/507c. When mounting other sights such as the Swampfox Kingslayer, you will use the 6-32 screws that came with your sight. This mount locks tightly into the carry handle and will block the view of the factory sights when installed. If you have any questions, feel free to ask.
