MDT Picatinny Scope Base, Ruger American SA, 20 MOA

• 20 MOA Incline: The built-in 20 MOA cant preserves more of a scope’s internal elevation travel, which is especially useful when stretching a rifle farther without running out of adjustment.
• Receiver-Specific Fit: This base is made for the Ruger American Rifle SA, giving the optic a stable mounting surface that follows the receiver profile for secure alignment and straightforward installation.
• 6061-T6 Aluminum Construction: The aluminum body keeps weight down while still providing the rigidity needed for a dependable scope mounting platform on a hunting or precision rifle.
• Picatinny Interface: The rail uses a Picatinny pattern, making it easy to pair the rifle with a wide range of scope rings and optic setups.
• Hard-Anodized Finish: The black anodized surface helps resist wear from repeated mounting, ring clamping, and field handling, so the base stays serviceable over time.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as practical optic-mounting solutions for bolt-action rifles across hunting, competition, long-range, and general shooting use. The series includes 20, 30, 40, and 50 MOA variants, allowing shooters to choose the amount of built-in elevation that best suits their cartridge, optic, and intended distance. Across the range, the design focus is straightforward: provide a rigid, repeatable interface between receiver and scope rings while keeping weight reasonable.

These bases are CNC-machined from 6061-T6 aluminum and finished with Mil-Spec Type II hard anodizing for durability in regular field use. The rails conform to MIL-STD-1913 and STANAG 4694 dimensions, which helps maintain compatibility with common Picatinny rings and accessories. MDT also shapes the underside to sit flush on the receiver and follow the ejection-port geometry, improving fit and helping the base integrate cleanly with the action. On models where the action design allows it, an integrated recoil lug adds another layer of resistance against movement under recoil.

About the MDT Picatinny Scope Base, Ruger American SA, 20 MOA

The MDT Picatinny Scope Base for the Ruger American Rifle SA is a fixed mounting rail designed for shooters who want a solid optic platform with added elevation built in from the start. Its defining feature is the 20 MOA incline, which shifts the scope’s adjustment range in a useful direction for longer-distance shooting. In practice, that means more available upward travel for dialing at distance while still keeping the setup suitable for general range use and hunting applications.

Because this model is made specifically for the Ruger American short action, it is shaped to match the receiver properly rather than relying on a generic rail profile. That receiver-specific fit matters for consistent ring alignment, secure mounting, and a cleaner overall interface between rifle and optic. The Picatinny rail format also gives the rifle broad compatibility with modern scope rings, making it easier to configure the optic position for eye relief and shooting style.

MDT builds the base from aluminum, which keeps the assembly light without giving up the stiffness expected from a scope base. The black finish adds surface protection against handling wear, while the 165.00 mm length provides ample mounting space for many riflescope ring placements. For a Ruger American setup intended for hunting optics or precision shooting optics, this base offers a simple mechanical upgrade that supports a more flexible and dependable scope installation.
