MDT Picatinny Scope Base, CZ 452, 40 MOA

• 40 MOA Inclination: built-in cant preserves more of the riflescope’s internal elevation travel, which is especially useful when setting up a rimfire or trainer rifle for longer distances.
• Picatinny Interface: the rail provides a standardized mounting platform for a wide range of scope rings and optics, making it easier to configure the rifle around the optic rather than the receiver’s original dovetail.
• 6061-T6 Aluminum Construction: the aluminum body keeps weight low while still providing the rigidity needed for a stable optic mount in regular field and range use.
• Receiver-Matched Underside Profile: the underside is shaped to sit flush on compatible actions and follow the ejection-port geometry, helping the base fit cleanly and mount securely.
• Hard-Anodized Finish: the black anodized surface adds wear resistance and corrosion protection, which helps the rail hold up to repeated optic changes and outdoor use.

About the MDT Picatinny Bases Series

MDT Picatinny Bases sit in the company’s mounting lineup as dedicated rails for shooters who want a solid optic interface on specific rifle actions. The series is offered in 20, 30, 40, and 50 MOA variants, allowing the user to choose the amount of built-in elevation bias that suits the rifle, cartridge, and intended distance. That makes the range relevant not only for hunting rifles, but also for competition setups, training rifles, and long-range rimfire builds where scope adjustment can become a limiting factor.

Across the series, the bases are CNC-machined from 6061-T6 aluminum and finished with Mil-Spec Type II hard anodizing. They follow MIL-STD-1913 and STANAG 4694 dimensions, so they provide a familiar Picatinny interface for modern scope rings and accessories. MDT also shapes the underside to sit flush on the receiver and to match the ejection-port geometry, giving the rail a cleaner fit than a generic one-size-fits-all base. On actions that allow it, an integrated recoil lug adds another layer of resistance to movement under recoil.

About the MDT Picatinny Scope Base, CZ 452, 40 MOA

The MDT Picatinny Scope Base, CZ 452, 40 MOA is built for shooters who want to move beyond the rifle’s factory dovetail and onto a full Picatinny mounting platform. For the CZ 452 pattern and related 11 mm or 3/8" dovetail-compatible rifles in this family, that means broader ring compatibility, easier optic positioning, and a more flexible setup for target shooting, hunting optics, or rimfire training rifles.

The defining feature is the 40 MOA incline. On rifles that are often used at extended rimfire distances, that extra cant helps preserve more of the scope’s upward adjustment, which can make the difference between a comfortable zero and a setup that runs out of elevation too early. It is a practical choice for shooters pairing compact actions with optics intended for precision work at longer ranges.

MDT machines the base from aluminium and finishes it in black hard anodizing, giving the rail a combination of low weight and everyday durability. The underside profile is shaped to sit flush on the receiver and follow the action geometry, which supports a cleaner fit and more consistent mounting. The rail format also makes the base a useful bridge between older dovetail-equipped rifles and modern optic mounting standards, especially when the goal is a more repeatable and adaptable riflescope installation.

About MDT

MDT Sporting Goods was established in 2009 and is based in British Columbia, Canada. The company focuses on rifle chassis systems and related equipment for target shooting and hunting, with a product range that includes chassis, stocks, magazines, bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, and the brand has grown around practical rifle-interface products designed to improve adjustability, mounting, and shooter fit.

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. The company also notes that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the functional, application-driven design seen across its rails and other rifle accessories.
