MDT scope base picatinny rails facilitate the seamless installation of optical devices. Constructed from 6061-T6 aluminum, these rails undergo a hard anodizing process to achieve a robust black finish. The underside is contoured to ensure a flush-fit on the receiver and to align with the ejection port's geometry. Featuring a 30 MOA incline, these rails offer enhanced elevation adjustment for your scope. Additionally, a recoil lug is incorporated into the underside profile on models compatible with this feature, contingent on the action's design. MIL-STD-1913 and Stanag 4694 specification rails are standardized mounting platforms used for attaching accessories to firearms, ensuring compatibility and precision Precision-engineered using 6061-T6 aircraft-grade aluminum, this CNC machined component ensures exceptional durability and performance Military specification type III hard anodizing enhances durability by providing a robust, wear-resistant surface, ideal for demanding applications 30 MOA picatinny scope base - precision-engineered rail for enhanced long-range accuracy, offering a 30 MOA elevation for optimal scope alignment The design is meticulously contoured to ensure smooth, snag-free operation, enhancing user experience by minimizing interruptions and maintaining seamless functionality
