For March Scopes, we adopt 1MOA: 1.047inch @100yard (True MOA) and 1MIL: 1/6283, 10cm@100m. We adopt this value for all our March Scopes. MOA stands for “Minutes Of Angle”. MOA is an angle (in minutes). The value obtained by dividing 1 degree of a circle’s circumference of 360 degrees by another 60 degrees is 1 MOA (1/60th of a degree). MIL (Milliradian) is also an angle, 1/6283 of 360 degrees, which means that 1 meter at 1000 meters is 1 MIL. To be precise, 1 meter of arc at 1 km away is 1 MIL.

We offer a maintenance and inspection service for a fee. Please contact info@deon.co.jp for further information.

We conduct an impact test up to 1000G (1000times of gravity). All our scopes can stand the impact of a 50cal recoil (including the 50 BMG) on usual shooting conditions.

In case the 0-set is stuck, please try the following instructions. Please click HERE.

The diopter adjustment range is from -2 to +2 for all March Scopes. Please wear your glasses when adjusting. Also please check the following for detailed instruction. “How to adjust the Eyepiece”

March Scopes are compatible to night visions. If you attach the night vision on the objective bell, you will be seeing the image of the night vision through the scope. Dark settings, level “1” or “2” in our 6 level illumination module will be adequate.
If you are attaching a night vision on the ocular side, even “1” or “2” in the 6 level illumination is too bright. Therefore, we developed an ultra low illumination module to accommodate to the night vision on the ocular side. Ultra low illumination is a very dark 4 level illumination module invisible to your naked eye. All our illumination modules are interchangeable.

By loosening the three screws indicated by the red arrows in the photo shown HERE, the side focus is free to rotate. It can be positioned by tightening the three places at the desired position. Another method is to paste a white piece of paper and write your distance on it. Please note that the focal point of any of these methods may change slightly depending on the condition of the eye on that day, the temperature, brightness, etc.

Please click HERE to see the line thickness and the center dot size for all the 4-40×52 and 6-60×56 Genesis reticles. Among these the non-illuminated FML-MT for 6-60×56 Genesis has the thinnest line and the smallest center dot.

We sometimes receive inquiries if scope rings need to be lapped. As a manufacturer of precision optical instruments, it is suggestable that you lap the scope rings. This is because while a single product will stay within tolerances and not cause problems, multiple products stacked on top of each other can add up to manufacturing tolerances and, in rare cases, exceed tolerances. However excessive lapping will lead to counterproductive effects and there are several precautions to take during the process. In most cases such as March Scope rings may not require lapping. The risk can overweigh the benefit of this process unless the rings are properly lapped by somebody proficient with right equipment. You need to make sure that the scope rail is not bent or lapping will be useless. If you are interested, it is highly recommended that you may consult your gun smith before performing. For your intellectual curiosity, please click HERE to see an article written by Satoshi Matsuo, a notable Deputy editor-in-chief at Gun Professionals Magazine and Guns & Shooting Magazine in Japan explaining why lapping the scope rings is necessary and the recommended instruction to do so.

Please see the chart below.

There are 3 types of reticles (wire, glass, fiber) depending on the manufacturing process. You can read more from here on how they are manufactured. https://marchscopes.com/news/10671/
(1) Wire reticle: It can be manually made thin and it’s mainly for benchrest shooting. Non-illuminated only.
(2) Glass reticle: The surface is etched using chemicals. The etched part is illuminated by a high reflected luminance LED. The brightness is proportional to the illuminated area for a glass reticle.
(3) Fiber reticle: LED is guided by the fiber and the cut surface of the tip itself is LED so this is the brightest reticle. Please see these videos to see how bright a fiber dot reticle is. In the video shows FD-1 reticle. https://www.youtube.com/watch?v=bvfclccnXUM&t=19s https://www.youtube.com/watch?v=nHXIuRjmTEk
