MDT Picatinny Scope Base, Winchester M70 SA, 20 MOA

• 20 MOA incline: adds built-in elevation to the mounting system, helping preserve more of the riflescope’s internal adjustment for longer shooting distances.
• Receiver-specific fit: the base is shaped for the Winchester M70 SA, which supports secure alignment and a clean fit over the action and ejection-port area.
• 6061-T6 aluminum construction: keeps the rail light while still providing the rigidity needed for dependable optic mounting on a hunting or precision rifle.
• MIL-STD-1913 and STANAG 4694 interface: gives broad compatibility with Picatinny-compatible scope rings and mounts, making optic selection and setup more straightforward.
• Hard-anodized black finish: improves surface durability and wear resistance, which matters when the rifle is carried often or the optic is removed and reinstalled over time.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as practical optic-mounting solutions for bolt-action rifles used in hunting, competition, long-range, and general shooting. The series covers a wide range of action types and lengths, giving shooters a receiver-specific base rather than a generic rail. Across the family, the design focus is straightforward: provide a stable interface between rifle and optic while keeping weight reasonable and installation geometry consistent.

The series is defined by 6061-T6 aluminum construction, a Mil-Spec Type II hard-anodized finish, and rail dimensions that conform to MIL-STD-1913 and STANAG 4694. Depending on the model, the lineup is offered in 20, 30, 40, and 50 MOA variants, allowing the base to be matched to the rifle’s intended distance envelope and the scope’s available elevation travel. MDT also profiles the underside of these rails to sit flush on the receiver and follow the ejection-port geometry, which helps maintain a tidy fit and reliable mounting surface. On actions that allow it, selected models incorporate an integrated recoil lug for added resistance to movement under recoil.

About the MDT Picatinny Scope Base, Winchester M70 SA, 20 MOA

The MDT Picatinny Scope Base for the Winchester M70 SA is a fixed mounting rail made for shooters who want a solid optic platform with added elevation built in. Its 20 MOA inclination is the key functional feature: by tilting the scope slightly downward relative to the bore, it helps keep more upward adjustment available inside the optic. In practice, that is useful for rifles set up for longer distances, while still remaining versatile enough for general field use.

This model is tailored to the Winchester M70 short action, so the rail geometry is intended to sit correctly on the receiver rather than relying on a one-size-fits-all pattern. MDT’s profiled underside helps the base sit flush and follow the action’s contours around the ejection port, which supports a neater installation and proper ring alignment. The rail itself is made from aluminum, keeping unnecessary weight off the rifle while still providing the stiffness needed for a dependable scope mount.

Because it follows the Picatinny standard, the base works with a broad range of compatible rings and mounts, making it suitable for hunting optics, tactical optics, or precision shooting setups. The black finish adds surface protection and a subdued appearance, while the fixed one-piece format keeps the mounting arrangement simple, stable, and easy to integrate into a rifle build centered on repeatable optic positioning.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on equipment for target shooting and hunting, with a product range that includes rifle chassis systems, stocks, magazines, bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, and the brand has grown around the idea of improving rifle ergonomics, modularity, and shooter interface.

MDT develops its chassis, magazines, and accessories with input from competitive precision shooters, which is reflected in the practical, application-driven design of its mounting components. In the optics-mounting category, MDT scope bases are CNC-machined from 6061-T6 aluminum and built to MIL-STD-1913 and STANAG 4694 specifications, aligning the brand closely with modern precision-rifle and hunting setups that depend on repeatable optic mounting.
