MDT Picatinny Scope Base, Round-Back Savage Model 110 SA, 40 MOA

• 40 MOA Inclination: built-in cant preserves more of a scope’s internal elevation travel, which helps when setting up a rifle for extended-range shooting.
• Receiver-Matched Profile: the underside is shaped to sit flush on the action and follow the ejection-port geometry, improving fit and helping the base seat consistently.
• 6061-T6 Aluminum Construction: the aluminum body keeps weight down while providing the rigidity needed for a stable optic mounting platform.
• MIL-STD-1913 and STANAG 4694 Interface: the rail pattern supports broad compatibility with Picatinny-style rings and mounts, making optic selection and future changes simpler.
• Hard-Anodized Black Finish: the anodized surface adds wear resistance and corrosion protection, useful on a rifle that sees regular field use or repeated optic changes.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as practical scope-mounting solutions for bolt-action rifles used in target shooting, hunting, and long-range work. Within MDT’s mounting lineup, this series covers a wide range of receiver footprints and action lengths, giving shooters a straightforward way to add a rigid Picatinny interface to a compatible rifle. The series is offered in 20, 30, 40, and 50 MOA variants, so the rail can be matched to the intended distance and the amount of elevation adjustment needed from the optic.

A defining feature of the series is its receiver-contoured underside, which is profiled to sit flush on the action and follow the ejection-port geometry. MDT machines these bases from 6061-T6 aluminum and finishes them with Mil-Spec Type II hard anodizing, balancing low weight with the durability expected from a hard-use rifle accessory. The rails conform to MIL-STD-1913 and STANAG 4694 dimensions, which supports consistent fit with Picatinny-compatible rings and mounts. On action designs that allow it, certain models also incorporate an integrated recoil lug to help manage stress under recoil.

About the MDT Picatinny Scope Base, Round-Back Savage Model 110 SA, 40 MOA

The MDT Picatinny Scope Base, Round-Back Savage Model 110 SA, 40 MOA is configured for shooters building a Savage short-action round-back rifle for applications where extra elevation matters. Its 40 MOA incline is the key feature: by angling the scope downward relative to the bore, it leaves more usable upward adjustment in the optic. In practice, that makes this base especially relevant for rifles set up for longer distances, where a flat rail may use too much of the scope’s adjustment range too early.

This model is made from aluminium and finished in black, giving the base a low-profile appearance and the corrosion resistance expected from a hard-anodized mounting part. The underside geometry is shaped for a close fit on the receiver, which helps the rail seat properly and supports stable ring alignment once the optic is installed. The 6-48 thread pattern matches the mounting arrangement used on the compatible Savage actions, while the Picatinny top interface keeps ring choice flexible for hunting optics, tactical optics, or precision shooting scopes.

For a rifle chambered and set up to stretch distance, the advantage of this base is not complexity but usable scope travel. A 40 MOA rail is a deliberate choice for shooters who already know they need more elevation reserve than a lower-incline base provides. On a compatible Savage Model 110 SA round-back and related actions, it creates a solid foundation for a scope system built around repeatable long-range adjustment.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on rifle equipment for target shooting and hunting, designing and manufacturing products such as chassis systems, magazines, buttstocks, 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 range today.

MDT’s development approach is closely tied to practical shooting use. The company states that its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the functional, compatibility-driven design seen across its mounting products. In the scope-base category, MDT is known for CNC-machined 6061-T6 aluminum construction and rails built to MIL-STD-1913 and STANAG 4694 specifications, reflecting a focus on repeatable fit and straightforward integration with modern optics.
