First Thoughts on the Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount
The Griffin Armament 30mm Cantilever GPM 1.5″ Height 15MOA Mount promises a robust and versatile solution for mounting optics on modern sporting rifles. Griffin Armament aims to deliver not just a mount, but a platform for accessory integration with their innovative AIS (Accessory Interface Suite). Having spent countless hours tweaking setups for optimal performance, I was eager to see if this mount lived up to its potential.
My main issue was finding a mount that not only provided the necessary height for comfortable shooting but also offered a way to streamline my accessories. Cluttered rails and awkward accessory placement were constant frustrations. The Griffin Armament mount’s AIS system seemed like a potential solution to declutter my rifle.
The mount arrived in a no-nonsense package, revealing a solid, matte black anodized mount. Its weight felt substantial, inspiring confidence in its durability, while the machining appeared precise and clean. Compared to a standard cantilever mount I’d been using, the Griffin Armament offering boasted more pronounced angles and the obvious AIS mounting points. I chose this mount over a LaRue Tactical or Geissele option, primarily due to the integrated 15 MOA and the promise of the AIS system.
Initially, I was impressed by the apparent quality and design. I was excited to finally address my accessory mounting woes and curious to see if the AIS system lived up to the hype.
