MDT Picatinny Scope Base, Browning X-Bolt SA, 20 MOA

• 20 MOA Incline: The built-in 20 MOA cant preserves more of a scope’s internal elevation for longer distances, which is especially useful on rifles set up for hunting, competition, and general long-range shooting.
• Receiver-Specific Fit: This base is shaped for the Browning X-Bolt short action, helping it sit flush on the receiver and align cleanly with the action for a secure optics platform.
• 6061-T6 Aluminum Construction: The aluminum body keeps weight down without giving up the rigidity needed for a stable scope mount, making it well suited to practical field rifles and range builds alike.
• MIL-STD-1913 and STANAG 4694 Profile: The rail follows common Picatinny standards, so it works with a wide range of compatible rings and optic mounts while maintaining consistent cross-slot dimensions.
• Hard-Anodized Finish: The black anodized surface adds wear resistance and corrosion protection, helping the base stand up to repeated mounting, transport, and outdoor use.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are designed as practical scope-mounting solutions for bolt-action rifles that need a stable rail and useful built-in elevation. Within MDT’s mounting lineup, the series covers a broad range of rifle actions and is offered in 20, 30, 40, and 50 MOA variants, allowing shooters to match the rail to their intended distance and optic setup. The 20 MOA configuration is the most versatile option in the family, making it suitable for hunting rifles, competition builds, long-range setups, and general shooting applications.

The series is built around CNC-machined 6061-T6 aluminum with a Mil-Spec Type II hard-anodized finish, combining low weight with the durability expected from a rifle-mounted component. MDT also builds these rails to MIL-STD-1913 and STANAG 4694 dimensions, which supports broad compatibility with Picatinny rings and mounts. A key design feature across the series is the profiled underside, which is shaped to sit flush on the receiver and follow the ejection-port geometry for a cleaner fit. On actions that allow it, certain models also incorporate an integrated recoil lug to improve resistance to movement under recoil.

About the MDT Picatinny Scope Base, Browning X-Bolt SA, 20 MOA

The MDT Picatinny Scope Base for the Browning X-Bolt SA is a fixed optics-mounting rail made for shooters who want a simple, rigid platform with added elevation built in. Its 20 MOA incline is the defining feature: by tilting the scope slightly downward relative to the bore, it helps preserve more upward adjustment in the optic. In practice, that gives a rifle more room for dialing at extended distance while still remaining useful on general-purpose hunting and target setups.

This model is tailored to the Browning X-Bolt short action, so the rail geometry matches the receiver footprint rather than relying on a generic one-size-fits-all shape. That receiver-specific contour helps the base sit properly on the action and supports consistent ring alignment. The rail is made from aluminum, which keeps the mount light while still providing the stiffness needed to hold zero reliably. Its black finish adds surface protection and gives the base a subdued appearance that suits both sporting and precision-oriented rifle builds.

Because the rail follows Picatinny dimensions, it gives the rifle a flexible mounting interface for a wide variety of compatible scope rings. That matters when setting up eye relief, ring spacing, or swapping optics between roles. With its combination of action-specific fit, practical 20 MOA cant, and straightforward fixed-rail design, this MDT base is well suited to shooters building a Browning X-Bolt SA for dependable field use or for stretching a scoped rifle farther on the range.

About MDT

MDT Sporting Goods was established in 2009 and is based in British Columbia, Canada. The company began in Chilliwack and identifies the TAC21 as its first chassis. MDT focuses on equipment for target shooting and hunting, with a product range that includes rifle chassis, stocks, magazines, bipods, scope bases, scope rings, and related accessories.

A defining part of MDT’s reputation is its emphasis on practical rifle-interface components developed with input from competitive precision shooters. That background is especially relevant in its mounting products, where fit, repeatability, and compatibility matter as much as raw strength. For scope bases, MDT states that its rails are CNC-machined from 6061-T6 aluminum and made to MIL-STD-1913 and STANAG 4694 specifications, reflecting the company’s focus on durable, standardized components for precision-oriented rifle setups.
