March MD Disks

• Light Reduction: MD disks reduce incoming light by up to 50% depending on conditions, which helps tame glare and can make the sight picture more comfortable in very bright environments.
• Improved Depth of Field: By limiting the amount of light entering the optic, the disk can increase perceived depth of field, helping more of the image appear acceptably sharp at once.
• Simple Scope Tuning: This accessory gives shooters a straightforward way to adapt a March riflescope to changing light without altering the optic itself.
• Minimal Added Weight: At 7.10 g, the MD disk adds very little mass, so it preserves the balance and handling of a precision rifle setup.
• Part of the March Accessory System: As part of the March Accessories range, the MD disk fits into a broader ecosystem built around model-specific scope optimization.

About the March Accessories Series

March Accessories is the support range developed around March rifle scopes, covering practical add-ons that help shooters tailor an optic to specific field and range conditions. The series includes sunshades, honeycomb hoods, MD disks, flip caps, illumination modules, focus wheels, and smartphone adapters, with compatibility varying by scope model and objective size. That model-specific approach reflects the broader March philosophy: accessories are meant to complement the optical and mechanical character of the scope rather than act as generic add-ons.

Within the series, each accessory addresses a distinct use case. Sunshades help control stray light and reduce flare, honeycomb hoods work as anti-reflective devices, and MD disks are intended to reduce incoming light and increase depth of field. Other accessories focus on handling and usability, such as flip caps that can lock fully open, or illumination modules designed for low-light and night-vision-oriented applications. Taken together, the series supports the needs of precision shooting, target work, and hunting optics users who want to fine-tune how their March scope behaves in real conditions.

About the March MD Disks

March MD Disks are a lightweight riflescope accessory designed to manage the way light enters the optic. Their main role is to reduce incoming light by up to 50%, depending on conditions, which can be useful when shooting in strong daylight, on reflective surfaces, or in situations where excessive brightness makes the image less comfortable to read. By moderating the light level, the disk can help produce a calmer sight picture and reduce the visual distraction that comes with harsh glare.

A second practical benefit is the way the MD disk can increase depth of field. For precision shooters, that can make it easier to keep more of the target scene appearing sharp at the same time, which is helpful when reading target detail or maintaining a more forgiving visual picture through the scope. This is especially relevant on high-magnification optics, where image presentation becomes more sensitive to light and focus conditions.

With a weight of only 7.10 g, the accessory adds almost nothing to the rifle system, so it does not meaningfully affect handling or balance. As part of the March Accessories family, the MD disk is intended for shooters who want a simple, non-intrusive way to adapt a March riflescope to challenging light conditions while preserving the core optical character of the scope itself.

About March

DEON Optical Design Corporation was established in 2004 in Japan and is headquartered in Chino, Nagano Prefecture. The company designs and manufactures the March brand of custom rifle scopes, with products assembled in Japan using Japanese-made components. March has built its reputation around precision-oriented optics for demanding shooting disciplines, including benchrest, long-range, and specialist tactical applications.

The brand’s lineup includes March-FX, March-X, Genesis, and High Master riflescopes, each aimed at different shooting requirements. March introduced its first 40×52 mm benchrest scope in 2007, and later expanded its optical technology with Super ED lenses in 2017. This focus on specialized optical design is also reflected in the accessory range, which is built to support the performance and application-specific setup of March scopes.
