Deon Optical Design are the creators and designers of MARCH Rifle Scopes, which are all hand-built in Japan by Japanese craftsmen using only genuine Japanese made parts to achieve the highest optical standards possible.
Shooters deserve the best possible optics to succeed in all aspects of competition, tactical, and hunting situations, for this reason Deon has produced a MARCH rifle scope for every situation.
Deon has over 5 decades of experience in optical design and manufacture, having previously designed some of the best selling scopes still in production today for other top manufacturers. With Deon’s focus and attention to detail makes the MARCH brand the ultimate in rifle scope design heading into the 21st century.




Outstanding 25% R&D ratio

Designed by expert engineers

March riflescopes are designed by our expert engineers. They have over five decades experience of designing high precision optical products including
riflescopes. March scopes are creations by their experience and knowledge to give hunter and shooter what they seek. In addition, they always develop new riflescopes continuously to seek innovation.


Robust body tubes – 4mm thick wall
The internal diameter of the 30mm tube and 34mm tube are the same at March Scopes. They are both 26mm. The walls of the 34mm tubes are 4mm thick. As we prioritize the durability of the scope, our 34mm body tube is simply just to make the scope extra strong. With its 4mm thick walls and the overall compact design, March-X and March-FX models are among the toughest riflescopes in the world.


Effort for ruggedness

Made in Japan

More than 150 parts used for March scopes are produced and supplied by Japanese manufacturers with the world’ s highest technology to achieve the highest optical performance and durability. No internal part is made of plastic excepting the few parts that cannot be made of metal or glass because of the function they serve; for example, an insulator for the lighted reticle mechanism.

Built for utmost precision level
Our scope bodies are manufactured by machining from solid aluminum bar stock. This process discards nearly 90% of the material during the machining process, but as a result we do not stress the material and we are able to manufacture a very stable body with uniform density throughout. We eliminate the smallest distortion or eccentricity in the body and ensure that the body is perfectly aligned and will stay aligned through repeated firing and abuse thus providing the shooter with a dependable precision instrument.

Machining aluminum bar

All hand made for longevity

Riflescopes have to stand recoil of the firing. Sometimes the shock goes up to 1000G. Obviously, optical and mechanical systems of riflescope require high durability. In addition, Riflescopes need to keep good performance even in severe weather condition during hunting and shooting. In order to overcome those conditions, March scopes are built precisely by hand by skilled craftsmen. All our March scopes are immensely strong to endure any severe conditions. They are Argon-filled for internal stability and are fully weather-resistant and waterproof to at least 4 meters, and have passed impact tests of up to 1000G. And then March Scopes which have passed 20 inspection items can be shipped out.


Deon is the Pioneer in using ED glass, Super ED glass
All current production March riflescopes use ED glass or Super ED glass, except for the 24mm objective scopes. We are also the first and the only manufacturer to assemble a Temperature Anti-draft Lens in riflescopes.
