Griffin Standard GPM Riflescope Mount w/ Free Shipping and Handling — 3 models

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 allowing use of the Accessory Interface Suite (AIS) of products, affording ambidextrous modular accessory support. The unique patented design splits the rings on two parallel but offset planes allowing accessories to be mounted on five AIS mounting surfaces: top, left, right, and 45° left & right offsets affording unsurpassed, ambidextrous flexibility. A heavy emphasis on anatomically correct positioning of optics was placed on AIS products, leading to the development of the Rapid Transition Optics (RTO) plates. RTO plates position secondary non-magnified optics on optical centerline relationship with the stock comb for comfortable, rapid, targeting 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, Dr optic, Meopta, Insight Microdot, Burris Fastfire, Vortex Venom & Viper, CMORE STS, RTS, STS2, and Vortex Razor, Wilcox Raptar Mount, and Simrad Adaptor Plate. Picatinny AIS plates are also offered. Other accessories will be developed to support future market technology, keeping the system at the forefront of the precision space. Optic height is determined by measuring from the top of the picatinny rail to the centerline of the tube diameter. To find the height to the bottom of the ring cradle, subtract the radius of the tube diameter from the height shown. -
