The Griffin Precision Mount (GPM) mounts 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.
