Griffin Armament SPRM Cantilever 30mm

SPRM Cantilever Features Made in the USA the Superior Precision Rifle Modular Mounts (SPRM) 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. It is machined on state-of-the-art multi-axis CNC equipment from solid aircraft-grade aluminum bar stock. The SPRM mounts bring unsurpassed flexibility and utility to the discriminating user. Left-handed or right-handed shooters are equally supported with the SPRM mounts and accessories. The Rapid Transition Optic (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. These plates currently support: 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 and viper CMORE STS RTS STS2 and vortex razor. The SPRM allows for the incorporation of the Accessory Interface Suite (AIS) of products which brings ambidextrous modularity and universal accessory support. The unique patent-pending design splits the rings on two parallel but offset planes allowing accessories to be mounted on 5 AIS mounting surfaces. This system affords left and right sides left and right 45-degree surfaces as well as the top surface to be used for accessory interfaces.
