What is the value of MOA and MIL used in March Scopes?

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.

Can I just have the scope inspected?

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

What is the diopter adjustment range of March Scopes?

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”

Is March Scopes compatible to Night Visions?

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.

How do I ship back the scope to Japan for service?

First please contact our repair center at info@deon.co.jp. Please tell us the model number, serial number and the symptoms. Our repair center will instruct you how to fill in the invoices when shipping back to Japan. Please do not ship by UPS, Fedex or DHL. We recommend that you ship back to us by EMS(International Postal service) as it is faster for us to receive your scope. Please click HERE to see your country’s postal service. Please contact us if you have any questions. Thank you!

Can I loosen the side focus turret and mark it?

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.

Is it necessary to lap the scope rings?

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.

Which reticles are the brightest? How bright are the fiber dot FD-1 and FD-2 reticles?

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

Can I buy a March Scope in Japan?

Thank you for considering visiting our country. Though we greatly appreciate you thinking of purchasing March Scope in Japan, it may be easier for you to purchase at your local dealer for reasons below. (1) Our factory only manufactures scopes after we receive orders so unfortunately we do not have any scopes in stock. As it currently takes about 3 months to hand assemble the scopes, you would need to order in advance. (2) You would need to get an export permit on your own as scopes are considered weapons in Japan. In case you are caught by the customs without an export permit, there is a possibility that your scope may be confiscated. (3) The documents are all written in Japanese.

Will March Scopes sponsor me?

We appreciate you wanting March to sponsor you! The support we receive from our customers over our products means a great deal to us. However, since March is a small manufacturer, we simply cannot sponsor all the requests we receive. We are currently not offering any sponsorships. Thank you for considering our brand!

Are there ways to get March Scopes to focus better?

Please refer to the check list below explaining the diopter adjustment, mounting position of the rings, torque value of the rings and the adjustment of the side focus. We hope that you’ll be able to acquire an even sharper image. Please click here to see the check list.

What is the brightness difference of illumination modules? Can they be used with Night visions?

We have 3 types of illumination modules : 6 level switch (new standard), 4 level switch (old standard) and the new Ultra Low 4 level illumination switch. These fit into all March scopes. If you purchase another type of illumination module, you can easily replace it tool less. Depending on the illumination module, the brightness differs. Standard 6 level illumination switch can be used for night visions attached on the objective side and Ultra low 4 level illumination switch can be used for night visions attached on the ocular side. Please click HERE to learn more.

Can you replace the tactical or normal turrets to the new shuriken lock turrets?

Unfortunately the scope structures with/without the shuriken lock turrets are different and the axis of the shuriken lock does not fit the scope body without shuriken lock turrets. Therefore, we are sorry for not being able to offer a replacement service. However, please be assured that tactical turrets will not move easily and normal turrets are capped.

Can current SFP reticles be assembled in the new 8-80×56 Majesta scope and vice versa?

The eyepiece for normal SFP scopes is about 20 degrees, whereas the 8-80×56 High Master Wide Angle Majesta scope has a wide 25 degrees eyepiece. Unfortunately the inner structure is different between eyepieces with different degrees and we can’t assemble each other’s reticles into the other. That is why new reticles for 8-80×56 High Master Wide Angle are specially made.

How do I loosen a stuck zero set?
