Product Description The Griffin Armament Griffin Precision Mount (GPM) is a premium, unibody scope mount machined in-house in Watertown, WI from lightweight aircraft-grade 6061-T6 aluminum. Designed for 30mm scope tubes and featuring a 1.1" mounting height at 0 MOA, this mount incorporates Griffin&';s patented AIS (Accessory Interface Suite) technology.

With STANAG 4694 compliant rail attachment for precise return to zero and Type 3 milspec hardcoat anodizing for lasting durability, the GSM1.1H30MM is a purpose-built solution for demanding precision rifle and tactical applications. Backed by a Lifetime Warranty and a utility patent, this mount delivers unsurpassed modularity and reliability.
