MDT Picatinny Scope Base, Marlin 336, 20 MOA

• 20 MOA incline: adds built-in elevation to the mounting surface, helping preserve more of the riflescope’s internal adjustment for longer distances while still working well for general hunting and range use.
• 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 clean optic alignment.
• Aluminium construction: keeps weight down without giving up the rigidity needed in a scope base, making it a practical choice for lever-action hunting rifles that are carried often.
• Picatinny interface: provides broad compatibility with Picatinny scope rings and accessories, giving more flexibility in eye-relief positioning than many two-piece base setups.
• Black anodized finish: adds surface protection against wear and handling marks while keeping the base visually discreet on blued, coated, or matte-finished rifles.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as practical optic-mounting solutions for shooters who want a rigid rail with the geometry and elevation needed for modern riflescopes. Within MDT’s mounting lineup, this series covers multiple action patterns and is offered in 20, 30, 40, and 50 MOA variants, allowing the shooter to choose how much built-in incline best suits the rifle and intended distance. The rails conform to MIL-STD-1913 and STANAG 4694 dimensions, so they work with a wide range of Picatinny-compatible rings and mounts.

A defining trait of the series is its focus on fit and usable elevation. The inclined rail profile helps a scope retain more upward travel for longer shots, while the underside is contoured to sit flush on the receiver and follow the ejection-port shape. MDT machines these bases from 6061-T6 aluminum and finishes them with hard anodizing, balancing low weight with the durability expected from a rifle-mounted component. In practice, the series is aimed at shooters who want one-piece rail convenience for hunting, competition, long-range, and general shooting, with a design that emphasizes repeatable mounting and broad compatibility.

About the MDT Picatinny Scope Base, Marlin 336, 20 MOA

The MDT Picatinny Scope Base, Marlin 336, 20 MOA is tailored for classic Marlin-pattern lever actions that benefit from a modern optic interface. By replacing traditional base arrangements with a one-piece Picatinny rail, it gives more freedom to position scope rings for proper eye relief, which is especially useful when setting up compact hunting optics or accommodating different stock dimensions and shooting positions. The rail is also compatible with other listed actions in the same footprint family, making it a versatile choice for several lever-action platforms.

The key functional feature is the 20 MOA inclination. On a rifle that may be used both in the field and on the range, that built-in cant helps preserve more of the scope’s internal elevation adjustment, which can be useful when stretching distance beyond a basic zero. At the same time, 20 MOA remains moderate enough to suit general-purpose setups rather than only specialized long-range builds. The aluminium construction keeps the base light, so it does not add unnecessary bulk to a rifle that is often carried for long periods.

MDT’s rail design also emphasizes fit and durability. The underside profile is intended to sit flush on the receiver, supporting stable contact and consistent mounting. Finished in black, the base blends well with most hunting and sporting rifles while offering a protective surface treatment for regular field use. For shooters fitting a Marlin 336-family rifle with modern glass, this base provides a straightforward way to add Picatinny compatibility and useful elevation in one component.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company built its name around rifle chassis systems and later expanded into a broader range of shooting accessories, including stocks, magazines, bipods, scope bases, and scope rings. MDT identifies the TAC21 as its first chassis, and its product development has been shaped by input from competitive precision shooters.

Today, MDT designs, manufactures, and sells equipment for target shooting and hunting, with a strong focus on practical rifle-interface components. That background is directly relevant to products like its scope bases, which are designed around repeatable mounting, action-specific fit, and compatibility with modern optics. In the mounting category, MDT is known for using CNC-machined aluminum construction and rail dimensions aligned with established Picatinny standards, reflecting the company’s emphasis on functional, rifle-specific hardware.
