Q. One of the most common questions I am being asked is how Sight Mount is mounted to the slide and whether or not the third hole is needed.
A. Here is my standard answer. Sight Mount comes with a dovetail block that fits snugly into the existing rear sights dovetailed slot after the rear sight is removed. 2 #6×48 screws with external star lock washers and Locktite secure Sight Mount to this block. A centered hole is drilled and tapped for the third screw that matches the third hole on Sight Mount. It is a .156 inch deep blind hole which is tapped to the bottom of the hole. This third mounting point uses only a screw and Loctite, no washer is used. Using all three holes the mount is rock solid, always centered, and parallel to the bore which allows a quality RMR to return to “0” when removed and replaced.
I still get asked, “Can the third screw be left off”? My answer is the same as Burris’ in their packaging, “A third hole is provided for a competent gunsmith to add the third screw” I will add Sight Mount considers this proper installation. It simply makes no sense to me to not use it, as any sight is only as accurate as the security it is mounted with. Sight Mount has been designed for LE and Military use and becomes the weapons permanent rear sight. Shortcuts are not an option in my opinion, as lives depend on it’s performance. Most people would never think of only using one of their scope base’s available screws on a rifle as accuracy WILL be affected, Sight Mount is no different. Mounted properly it will excel at its intended purpose.
Q. What is Sight Mount made out of?
A. Sight Mount is machined from a block of 6061 T6 Aluminum to Military specs for MIL-STD-1913 (Picatinny) rail. It is then hard anodized to Mil Spec.
