The German Precision Optics (GPO) SetBack 3” Cantilever Extension Mount delivers an exceptionally stable, lightweight optical attachment solution built specifically for Modern Sporting Rifles and flat-top Picatinny rail environments. It is meticulously engineered from high-grade aircraft aluminum alloy to withstand punishing recoil impulses while maintaining perfect zero alignment across long-term deployments. The specialized 3-inch forward offset architecture allows shooters to mount high-magnification scopes or Low Power Variable Optics (LPVOs) further forward over the receiver, ensuring ideal head placement and safe eye relief without shifting body position on the rifle stock. Featuring precision-bored 30mm rings secured via multi-bolt caps for robust scope retention, its non-reflective matte black anodized coat offers a professional look perfect for competitive match shooters, tactical operators, and field hunters alike.
