MDT Picatinny Scope Base, CZ 457, 50 MOA

• 50 MOA Incline: the built-in cant preserves more of a scope’s internal elevation travel, which is especially useful on rimfire and long-range setups where extra adjustment helps reach distant targets without resorting to holdover alone.
• Receiver-Specific Fit for CZ 457: this base is shaped for the CZ 457 action so it sits flush on the receiver and follows the ejection-port geometry, giving a cleaner installation and dependable optic alignment.
• 6061-T6 Aluminum Construction: the aluminum body keeps weight low while still providing the rigidity needed for a stable optic platform on a rifle used for regular range work or field use.
• MIL-STD-1913 and STANAG 4694 Rail Profile: the standardized Picatinny interface makes it easier to pair the base with a wide range of scope rings and mounts while maintaining consistent cross-slot engagement.
• Hard-Anodized Black Finish: the anodized surface improves wear resistance and helps the base stand up to repeated mounting, handling, and exposure to typical outdoor conditions.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are designed as dedicated optic-mounting rails for bolt-action rifles, with the series covering a wide range of action patterns and receiver lengths. Within MDT’s accessory lineup, they serve shooters who want a solid interface between rifle and scope without adding unnecessary bulk. The series is offered in 20, 30, 40, and 50 MOA variants, allowing the rail to be matched to the intended role, from general shooting to applications where additional elevation travel becomes important.

A defining trait of the series is its combination of 6061-T6 aluminum construction, a Mil-Spec Type II hard-anodized finish, and rail dimensions made to MIL-STD-1913 and STANAG 4694 standards. In practical terms, that means broad compatibility with Picatinny rings and a lightweight but rigid mounting platform. MDT also shapes the underside to sit flush on the receiver and to follow the ejection-port geometry, which helps the base install neatly and maintain proper fit. On action designs that allow it, the series also incorporates an integrated recoil lug for more secure indexing under recoil.

About the MDT Picatinny Scope Base, CZ 457, 50 MOA

The MDT Picatinny Scope Base, CZ 457, 50 MOA is built for shooters who need substantial additional elevation in a compact, rifle-specific mounting solution. Its 50 MOA incline is the key feature: by angling the scope downward relative to the bore, it frees up more usable upward adjustment inside the optic. That matters on rifles set up for extended-distance shooting, where a conventional flat base can leave valuable turret travel unused. On a CZ 457, this is particularly relevant for precision rimfire setups that are often pushed well beyond typical smallbore distances.

The base uses a Picatinny rail interface, giving the rifle a flexible platform for modern scope rings and optic placement. Because the underside is profiled to sit flush on the receiver and match the ejection-port geometry, the rail is not just compatible on paper; it is shaped for a tidy, stable fit on the action. MDT machines the base from 6061-T6 aluminum, which keeps the assembly light while still providing the stiffness needed to support repeatable optic alignment. The black anodized finish adds surface durability, helping the rail resist wear from installation and normal handling.

For a CZ 457 owner building a rifle around target shooting, training, or long-range rimfire work, this base provides a practical foundation. It does not change the rifle’s handling dramatically, but it does expand what the optic can do by making more of the scope’s adjustment range available where it is most useful.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle systems and accessories for target shooting and hunting, with a product range that includes chassis systems, magazines, buttstocks, bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, and that early emphasis on modular rifle platforms still shapes the brand’s product development.

For mounting components such as scope bases, MDT is known for practical, shooter-oriented engineering. The company states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the strong focus on fit, repeatability, and compatibility across modern rifle setups. In the optics-mounting category, MDT’s bases are CNC-machined from 6061-T6 aluminum and made to MIL-STD-1913 and STANAG 4694 specifications, reflecting the same functional design approach seen across its broader rifle accessory lineup.
