Product DescriptionThe Griffin Armament GPM (Griffin Precision Mount) is a premium one-piece scope mount and ring combo engineered for precision rifle shooters. Machined in-house in Watertown, Wisconsin from lightweight aircraft-grade 6061?'T6 aluminum and finished in durable black anodizing, the GPM integrates the Accessory Interface Suite (AIS) for truly ambidextrous accessory mounting. Its patented design splits the rings on two parallel but offset planes, creating five AIS mounting surfaces-top, left, right, and 45Adeg left/right-for unsurpassed flexibility. Optimized for anatomical optic positioning, the system supports Rapid Transition Optics (RTO) plates to add a secondary, non-magnified optic that aligns naturally with the shooter's stock comb for fast target acquisition. This 30mm model includes mounting hardware and is built to deliver rugged reliability in the field or on the range.Product HighlightsAmbidextrous AIS platform with five mounting surfaces (top, left, right, and 45Adeg left/right)Precision-machined 6061?'T6 aluminum with tough black anodized finishRTO plates maintain optical centerline for fast, comfortable transitions to secondary optics30mm ring bore in a rigid one-piece mount for repeatable zero and stabilityMachined in Watertown, WI, USA; includes mounting hardwareSpecsProduct Type: Scope mount/ring comboModel: GPMTube Diameter: 30 mmMaterial: 6061?'T6 aluminumFinish/Color: Black anodizedAccessory System: Accessory Interface Suite (AIS); supports Rapid Transition Optics (RTO) platesManufacturing Location: Watertown, WI, USAUPC: 689396839953Manufacturer Part Number: GSM1.425H30MMBrand Name: GRIFFIN ARMAMENTDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
