The AIS™ Flat Plate Picatinny Adapter is a precision-machined mounting plate designed exclusively to work with Griffin Armament’s GPM™ optics-mount line via the AIS (Accessory Interface Suite). It provides a flat, low-profile platform to attach secondary, non-magnified optics or other Picatinny-style accessories (flashlights, lasers, bubble levels, data cards, etc.) alongside the primary scope. The plate is built from 6061-T6 aluminum, hardcoated to Type-3 mil-spec anodizing for durability and corrosion resistance. It features dowel-pin alignment for repeatable positioning and rigidity, mounting holes on five sides to suit left- or right-handed setups, and is manufactured in the USA. The unit carries a perpetual lifetime warranty. Mounting screws: 8-40 × 7/16-inch, T-15 Torx 6 screwsTapered pins Griffin Armament Picatinny AIS™ Flat Plate GSMA-PIC-FP
