MDT Picatinny Scope Base, CZ 457, 20 MOA

• 20 MOA Inclination: The built-in 20 MOA cant preserves more of a scope’s internal elevation travel, which is especially useful when stretching a rimfire rifle like the CZ 457 to longer distances.
• Receiver-Matched Profile: The underside is shaped to sit flush on the action and follow the ejection-port geometry, helping the base seat cleanly and align consistently during installation.
• 6061-T6 Aluminum Construction: The aluminum body keeps weight down while providing the rigidity needed for a stable optic interface on hunting, training, and precision rimfire rifles.
• Picatinny Standard Interface: Built to MIL-STD-1913 and STANAG 4694 dimensions, the rail gives broad compatibility with Picatinny scope rings and other optic-mounting accessories.
• Hard-Anodized Finish: The black anodized surface improves wear resistance and helps the base stand up to repeated scope changes, handling marks, and field use.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are designed as practical scope-mounting solutions for bolt-action rifles used in hunting, competition, long-range shooting, and general range work. Within MDT’s mounting lineup, this series covers the core need for a rigid, correctly profiled rail that gives the shooter a standardized Picatinny interface without unnecessary bulk. The family is offered in 20, 30, 40, and 50 MOA variants, allowing the rifle to be set up around the optic’s available elevation travel and the intended shooting distance.

Across the series, the rails are CNC-machined from 6061-T6 aluminum and finished with Mil-Spec Type II hard anodizing. They conform to MIL-STD-1913 and STANAG 4694 dimensions, so ring fit and accessory compatibility remain consistent across different rifle platforms. A defining characteristic of the series is the contoured underside, which is shaped to sit flush on the receiver and follow the ejection-port geometry for a cleaner fit. On action types that allow it, MDT also integrates a recoil lug into the rail profile to improve resistance to movement under recoil.

About the MDT Picatinny Scope Base, CZ 457, 20 MOA

The MDT Picatinny Scope Base, CZ 457, 20 MOA is built for shooters who want to mount a scope securely on the CZ 457 while gaining useful additional elevation for longer-range rimfire work. On a platform often used for target shooting, small-game hunting, and precision training, a 20 MOA rail helps keep more of the scope’s adjustment range available where it matters. That makes it easier to pair the rifle with optics intended for dialing, rather than forcing the scope to operate near the limit of its internal travel.

The base uses a Picatinny interface made to MIL-STD-1913 and STANAG 4694 specifications, so it works with a wide range of scope rings and optic setups. Its 6061-T6 aluminum construction keeps the assembly light without giving up the stiffness needed for repeatable optic alignment. The black hard-anodized finish adds surface durability, which matters on a rifle that may see frequent scope changes or regular transport to the range and field.

MDT also shapes the underside of the rail to sit flush on the receiver and match the action geometry more closely. In practice, that gives the installation a cleaner fit and a more purpose-built feel than a generic rail. At 165.00 mm in length, this fixed scope base provides ample mounting space for ring placement, making it easier to position the optic correctly for eye relief and overall rifle balance.

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 since expanded into a broad ecosystem of rifle accessories shaped by practical use on modern precision rifles.

MDT develops its chassis, magazines, and accessories with input from competitive precision shooters, which helps explain the company’s emphasis on fit, repeatability, and compatibility. In the mounting category, MDT states that its scope bases are CNC-machined from 6061-T6 aluminum and made to MIL-STD-1913 and STANAG 4694 specifications. That background makes MDT a well-established name for shooters building rifles around stable optics mounting and modular precision-rifle components.
