MDT Picatinny Scope Base, CZ 455, 20 MOA

• 20 MOA Incline: the built-in forward cant preserves more of a scope’s internal elevation travel, which is especially useful when stretching a rimfire or trainer rifle to longer distances.
• Receiver-Specific Fit: this base is shaped for the CZ 455 pattern so it sits cleanly on the action, helping maintain alignment and giving the optic a stable mounting surface.
• 6061-T6 Aluminum Construction: the aluminum body keeps weight down while still providing the rigidity needed for repeatable scope mounting on a working rifle.
• Picatinny Standard Interface: the rail follows MIL-STD-1913 and STANAG 4694 dimensions, making it easier to pair the base with a broad range of rings and optic mounts.
• Hard-Anodized Finish: the black anodized surface adds wear resistance and corrosion protection, which helps the base hold up to regular handling, weather, and repeated optic changes.

About the MDT Picatinny Bases Series

MDT Picatinny Bases are built as practical optic-mounting solutions for shooters who want a secure rail with geometry matched to specific rifle actions. Within MDT’s mounting lineup, this series covers a wide range of receiver patterns and is offered in 20, 30, 40, and 50 MOA variants, allowing the shooter to choose the amount of built-in incline that suits the rifle and intended distance. That makes the series relevant not only for hunting rifles, but also for competition, training, and general target shooting setups.

The series is defined by a straightforward mechanical approach: CNC-machined 6061-T6 aluminum, a receiver-contoured underside, and a rail profile made to MIL-STD-1913 and STANAG 4694 standards. In practice, that means broad compatibility with modern scope rings and a fit designed to sit flush on the action while respecting ejection-port geometry. On models where the action design allows it, MDT also integrates a recoil lug into the underside profile. The result is a family of bases aimed at shooters who want dependable scope positioning, low unnecessary weight, and extra elevation travel from an inclined rail.

About the MDT Picatinny Scope Base, CZ 455, 20 MOA

The MDT Picatinny Scope Base, CZ 455, 20 MOA is intended for shooters who want to mount a riflescope on a CZ 455 with a more versatile elevation setup than a flat base can provide. The key feature is the 20 MOA incline, which angles the scope slightly downward relative to the bore so more of the optic’s upward adjustment remains available. On a rimfire rifle, that matters when moving from short-range zeroing to longer-range target work, where bullet drop quickly becomes more significant.

This base also solves the practical side of scope mounting. Its 145.00 mm length gives a stable platform for ring placement, while the Picatinny format makes it easier to position optics with the eye relief and ring spacing a particular scope requires. Because the rail is made from aluminium, it adds useful mounting capability without making the rifle unnecessarily heavy. The black finish keeps the appearance subdued and adds surface protection for field or range use.

As part of MDT’s Picatinny base design, the rail follows recognized Picatinny dimensions and uses a receiver-matched profile rather than a generic one-size-fits-all shape. That helps the base sit properly on the action and supports consistent optic alignment. For a CZ 455 set up as a hunting rimfire, training rifle, or precision small-bore platform, this rail provides a simple but important upgrade: a stronger mounting interface and more usable scope adjustment for distance.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company is known for designing and manufacturing rifle chassis systems, magazines, buttstocks, and shooting accessories for target shooting and hunting. MDT identifies the TAC21 as its first chassis, and that early focus on modular rifle platforms still shapes the brand’s product range today.

MDT develops its products with input from competitive precision shooters, which is reflected in the company’s emphasis on practical fit, repeatability, and compatibility across rifle systems. Its lineup now includes chassis, stocks, magazines, bipods, scope bases, and scope rings. 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, aligning them with the same precision-oriented approach seen across the rest of the brand’s shooting equipment.
