Although Griffin Armament is best known for its signature reducing sound suppressors, which are also coveted sniper tools, founders Austin and Evan have combined their lifelong passion for precision rifle shooting, and nearly a decade of notable research and development into a new product line, The Griffin Precision Mount™ (GPM™).

GPM™ mounts are machined in-house in Watertown, WI from aircraft-grade 6061-T6 aluminum. They boast a dowel pin alignment system that enhances precision and fortifies the assembly. This translates to enhanced rigidity, superior alignment, and consistent return to zero with each use.

GPM™ mounts allow the incorporation of the Accessory Interface Suite (AIS™) of products, which brings ambidextrous modularity and universal accessory support to the precision optics mount marketplace. 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. GPM™ mounts bring unsurpassed flexibility, utility, and rigidity to both left and right-handed shooters.

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.
