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.
Features:
- AMERICAN MANUFACTURED at GRIFFIN HQ
- AIS™ Technology (Accessory Interface Suite) Allowing the user to mount accessories wherever they desire.
- RTO™ Accessory Support (Ability to mount Rapid Transition Optic™ plates to the system for a 40° co-witness to the primary optic)

Outstanding!!! These scope mounts rock?

Got one of these to replace the crappy rings I had on my bolt gun and holy crap am I happy I did! The rings I had were such a pain in the ass to get right and they would lose zero if I hit a pothole too hard driving to the range. This mount has never come loose on me, and I think the one-piece design makes it MUCH more solid. Missed a 12-pointer last season, but I won’t let that happen again!

Really tough design. I’d rather have a few more in a mount and not have to worry about being gentle with it. This thing is built like a tank. My only suggested improvement would be to machine some of the clamping bar to make it even with the flat part of the mount directly under the turrets. I had to take the clamping bar off to use the feeler gauge method to level the scope. Not really a complaint, since I know the clamp is stronger without the machining.

These are one of the best mounts I have ever encountered in my decades of building and shooting long range rifles.. They are precision and one of the strongest mounts in aluminum I have ever bought. No need to lap and offer great functionality in mounting red dots of other piggy back sights..You won’t be sorry with the quality at this affordable cost. I have paid nearly as much for far less quality weaker 34mm mounts and will be switching them to these.
