MDT Picatinny Scope Base, CZ 455, 50 MOA

• 50 MOA Inclination: adds substantial built-in elevation to the mounting platform, helping preserve more of the riflescope’s internal adjustment for extended-range shooting with rimfire and other cartridges that need significant holdover.
• Receiver-Matched Profile: the underside is shaped to sit flush on the action and follow the ejection-port geometry, which supports a secure fit and cleaner optic alignment on the rifle.
• 6061-T6 Aluminum Construction: keeps the base light while still providing the rigidity needed for a stable optic interface, so weight stays low without giving up mounting security.
• Picatinny Specification Interface: the rail follows MIL-STD-1913 and STANAG 4694 dimensions, giving broad compatibility with Picatinny scope rings and other rail-mounted optics accessories.
• Hard-Anodized Finish: the black anodized surface improves wear resistance and corrosion protection, which helps the base stand up to repeated mounting, field use, and changing weather conditions.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as dedicated optic-mounting solutions for shooters who want a precise interface between rifle and scope without unnecessary bulk. The series is offered in 20, 30, 40, and 50 MOA variants, allowing the mounting setup to be matched to the rifle, cartridge, and intended distance. That makes the range relevant not only for general target shooting and hunting, but also for disciplines where preserving elevation travel in the riflescope becomes increasingly important.

Across the series, MDT uses 6061-T6 aluminum with a Mil-Spec Type II hard-anodized finish, combining low weight with the durability expected from a fixed rail. The rails are made to MIL-STD-1913 and STANAG 4694 specifications, so they accept common Picatinny-compatible rings and mounts. A key design trait is the profiled underside, which is shaped to sit flush on the receiver and follow the ejection-port geometry for a cleaner, more secure fit. On actions that allow it, certain models also incorporate an integrated recoil lug. In MDT’s lineup, these bases serve as practical mounting components for precision-oriented rifles used in target shooting, hunting, and long-range applications.

About the MDT Picatinny Scope Base, CZ 455, 50 MOA

The MDT Picatinny Scope Base, CZ 455, 50 MOA is a fixed mounting rail made for shooters who need considerably more elevation built into the rifle-to-scope interface. On a CZ 455, a 50 MOA base is especially useful when setting up a rimfire rifle for longer distances, where bullet drop quickly consumes a scope’s internal adjustment range. By adding cant at the base, this model helps keep more usable elevation in reserve, which is valuable for stretching a .22 LR platform well beyond typical zero distances.

The rail is machined from aluminium and finished in black, giving the setup a combination of low mass, corrosion resistance, and a clean match with modern rifles and optics. Its Picatinny-format top interface allows the use of a wide variety of compatible rings, making it easier to pair the rifle with target, hunting, or training optics. The underside profile is shaped to sit flush on the receiver and match the action geometry, which supports stable installation and consistent scope alignment. For practical use, that means a mounting platform designed not just to hold an optic, but to do so in a way that supports repeatability, maintains fit on the rifle, and gives the shooter more freedom to configure a long-range rimfire setup around the CZ 455 action.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company first identified the TAC21 as its initial chassis design, and it has since expanded into a broader range of shooting equipment for target shooting and hunting. MDT designs, manufactures, and sells rifle chassis systems, magazines, buttstocks, and accessories, with its catalog also covering bipods, scope rings, and scope bases.

Within this category, MDT is particularly known for building practical mounting components that reflect the needs of precision shooters. The company states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which fits the functional, no-frills design approach seen in its rails and bases. For scope mounting products, MDT uses CNC-machined 6061-T6 aluminum and builds to MIL-STD-1913 and STANAG 4694 rail standards, emphasizing fit, compatibility, and repeatable alignment.
