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. 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.

Although the emphasis of the GPM™ mounts are on the utility they provide, much care and attention was also given to the engineering, precision, and durability of the mounts themselves. Unlike many market offerings which emphasize manufacturing ease, often bolting split rings to a base adapter, the GPM™ foundation is a unibody base that cradles the optic eliminating extraneous parts and interfaces which are often traceable to loss of zero retention, or tolerance stacking and subsequent loss of interfacing accuracy. The addition of the dowel pin alignment interface - new with the GPM™ family of mounts - further reduces loss of zero potential and alignment accuracy. A precision rifle becomes a battle rifle with loss of zero, and serious precision shooters should not tolerate it.
GPM™ mounts are manufactured in the USA at Griffin’s Wisconsin manufacturing facility. Mounts are machined on state-of-the-art multi-axis CNC equipment from solid aircraft-grade aluminum bar stock. Manufacturing in house provides the ability to control quality at levels impossible in contract manufacturing. The geometries of Griffin GPM™ mounts are machined to part datums probed on each part. Prior to machining, costly manufacturing time is dedicated to each part with Renishaw probe strategies coupled with Renishaw RTS set tool magazines, which ensure critical geometries are machined to positional accuracies of +-.0002”, rather than depending on human loading accuracy in a much looser relationship to work-holding based datums like traditional optic mount industry manufacturing processes. Bringing Aerospace industry segmented production engineering concepts and inspection equipment to Optics mounts enhances the state of optical mount quality. This persistent dedication to quality ensures that the mount quality theory and the actual production mount quality are inseparably linked for uncompromising, superior precision.
In an industry space where raw extrusion, job shop quality, and an emphasis on efficiency over quality are normal, why does Griffin bring a wasteful level of manufacturing time and technology to Optic mounts? Because these aren’t just typical market, job shopped, optic mounts. These are Griffin Precision Mounts™. Gear made by snipers for everyone, GPM™ mounts are the next generation of sniper grade, precision rifle optic mounts.
