Product Overview
Product Description
Griffin Precision Mounts™ (GPM™) are machined in-house in Watertown, WI from lightweight aircraft-grade 6061-T6 aluminum. GPM™ mounts incorporate a dowel pin alignment system that allows use of the Accessory Interface Suite (AIS™) of products, providing ambidextrous modular accessory support. The patented design splits the rings on two parallel but offset planes, enabling accessories to be mounted on five AIS™ mounting surfaces: top, left, right, and 45° left and right offsets, delivering extensive ambidextrous flexibility.
A strong emphasis on anatomically correct optic positioning is a core feature of AIS™ products, leading to the development of Rapid Transition Optics (RTO™) plates. RTO™ plates position secondary non-magnified optics along the optical centerline in relation to the stock comb, allowing for comfortable and rapid target acquisition with a simple roll of the host firearm.
AIS™/RTO™ plates currently support: Griffin Micro Sight™ (GMS™), Aimpoint Acro, T1/T2, H1/H2, Comp M5, Sig Romeo, Vortex Spark, Trijicon RMR, SRO, Holosun HE507C, HS407C, HS508C, Leupold DeltaPoint, J-Point, Optima, Doctor Optic, Meopta, Insight Microdot, Burris FastFire, Vortex Venom & Viper, C-MORE STS, RTS, STS2, Vortex Razor, Wilcox Raptar Mount, and Simrad Adapter Plate. Picatinny AIS™ plates are also available. Additional accessories will continue to be developed to support emerging technologies, ensuring the system remains at the forefront of the precision shooting space.
Optic height is determined by measuring from the top of the Picatinny rail to the centerline of the tube diameter. To calculate the height to the bottom of the ring cradle, subtract the radius of the tube diameter from the listed height.
