Description
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.
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.

Got one of these included with my 1-8x LPVO since it was free. Figured I’d end up swapping it out for the SPUHR mount I love, but ended up keeping this on it instead because it worked so well. Can’t find a thing wrong with this, it’s a little chunky, but I like that because it feels 100% rock solid. I beat my carbines up pretty bad and this mount has never lost zero even after knocking it off the tailgate of my truck onto some concrete at the range. Thinking about picking up one of the red dots and a top mount plate to try out the accessory mounting surfaces… super happy with this!

Griffin mounts are now my go to mounts. They are extremely solid and lock up very well. They have that look of a Spuhr mount which is a good thing. The offset design of the rings is brilliant. The price point is spot on as this mount is worth every penny. Its the little things Griffin does as well. The torque specs are obviously in the manual but they are also on the bottom edge of the pic rail so you can always see what the settings are, even with the mount on, you just tilt your rifle and look at the underside edge.
