The mount is CNC machined from 7075-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Includes necessary screws to attach light body to mount. Requires a T15 Torx and 5/64" Allen wrench for installation (not included). The Surefire AA Scouts and Streamlight Protac Rail Mount HL-X are not compatible because the bodies are longer and cover one mounting screw, unless you are willing to modify an L-key Allen or Torx wrench to fit between the light body and mount. BCM KeyMod screws are covered under US Patent 9377274. Made in the USA..
Top right 45 degree flat: Due to the asymmetrical body of the Surefire Scout Light, placement of the front sight and light are more critical in this setup. The smaller sights like MBUS Pro and Knight's Armament Micro work fine, but the Troy, Diamondhead, and MBUS Gen II will not be able to clear the main body where the screw holes reside for the stock picatinny adapter. This means one or the other will have to be moved forward/back to get appropriate clearance. Another option is to use an Arisaka 300 Series Light Body or 600 Series Light Body, which will allow plenty of clearance.
