The Griffin Precision Mount (GPM) is engineered for unmatched modularity and precision. Machined in-house in Watertown, WI, from lightweight aircraft-grade 6061-T6 aluminum, these mounts are built for durability and performance. Featuring a dowel pin alignment system, the GPM seamlessly integrates with the Accessory Interface Suite (AIS), providing ambidextrous modular accessory support. The patented ring design is uniquely split across two parallel but offset planes, allowing accessory attachments on five AIS mounting surfaces - top, left, right and 45 deg left and right offsets - for superior customization. Designed with ergonomic optic positioning in mind, the Rapid Transition Optics (RTO) plates enable fast, intuitive target acquisition by maintaining an optimal optical centerline with the stock comb. This allows for seamless secondary optic use with a simple roll of the firearm. AIS/RTO plates support a variety of industry-leading optics, including Griffin Micro Sight (GMS), Aimpoint Acro, Trijicon RMR, Sig Romeo, Vortex Razor, Leupold Deltapoint and more. Additionally, picatinny AIS plates are available, with new accessories continually in development to ensure GPM remains at the forefront of precision shooting technology. AIS technology (accessory interface suite) allows users to mount accessories wherever they desire, providing ultimate flexibility and convenience RTO accessory support allows for a 40 degree co-witness with primary optics The dowel pin alignment interface ensures precise and accurate positioning of parts during assembly, enhancing the overall integrity of the build Versatile ambidextrous support designed for left and right handed users, ensuring universal accessibility and comfort Unibody construction increases structural integrity and overall durability Individually probed datum's drive all machining during manufacturing for unmatched dimensional consistency Stanag 4694 compliant attachment ensures precise return to zero for consistent accuracy Type 3 Mil-Spec hard coat anodizing enhances resistance to corrosion and wear Lightweight 6061-T6 aluminum construction matches optics materials while maintaining strength and affordability Utility patented to support ongoing technological advancements in electro-optics Backed by a perpetual lifetime warranty for ultimate confidence in long term reliability
