MDT Picatinny Scope Base, CZ 527, 20 MOA

• 20 MOA Inclination: The built-in forward 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 shaped for the CZ 527 action family, helping it sit flush on the receiver for a secure interface and consistent scope alignment.
• 6061-T6 Aluminum Construction: The aluminum body keeps weight low while providing the rigidity needed for a stable optic mount on a hunting or general-purpose rifle.
• Picatinny Standard Interface: Built to MIL-STD-1913 and STANAG 4694 dimensions, it gives broad compatibility with Picatinny scope rings and simplifies optic selection.
• Hard-Anodized Finish: The black anodized surface adds wear resistance and corrosion protection, helping the base hold up to repeated mounting, field use, and changing weather.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are designed as practical optic-mounting solutions for bolt-action rifles used in hunting, competition, long-range, and general shooting. Within MDT’s mounting lineup, this series focuses on giving shooters a solid, receiver-specific rail with the geometry and incline needed for modern scoped setups. The family is offered in 20, 30, 40, and 50 MOA variants, allowing the user to match the rail to the rifle’s intended distance envelope and the amount of elevation travel needed from the optic.

A defining characteristic of the series is its combination of 6061-T6 aluminum construction, Mil-Spec Type II hard anodizing, and rail dimensions that conform to MIL-STD-1913 and STANAG 4694. In practical terms, that means a lightweight base with consistent ring compatibility and the durability expected from a rifle-mounted component. MDT also shapes the underside to sit flush on the receiver and follow the ejection-port geometry, which helps produce a cleaner fit. On actions that allow it, the design also incorporates an integrated recoil lug for added resistance to movement under recoil.

About the MDT Picatinny Scope Base, CZ 527, 20 MOA

The MDT Picatinny Scope Base, CZ 527, 20 MOA is built for shooters who want to mount a conventional riflescope on the CZ 527 platform while gaining additional elevation adjustment for longer shooting distances. The 20 MOA incline tilts the optic slightly forward, which helps preserve more of the scope’s usable internal adjustment. In practice, that gives the rifle more flexibility for distance work while still remaining suitable for general field use and hunting setups.

This model uses a Picatinny rail interface, so it accepts a wide range of ring options and makes it easier to position the scope correctly for eye relief and balance. Because the base is profiled for the receiver, it is intended to sit flush and match the action geometry rather than acting like a generic rail. That matters for mounting consistency, overall fit, and maintaining a stable connection between rifle and optic.

The base is made from aluminium and finished in black, giving it a combination of low weight, corrosion resistance, and a subdued appearance that suits both hunting rifles and practical range builds. As part of MDT’s scope-base design approach, the rail follows recognized Picatinny dimensional standards, which helps ensure dependable compatibility with quality rings and accessories. For a CZ 527 owner building a more capable scoped rifle, this base provides the key advantage of added elevation without adding unnecessary bulk.
