Different Sizes of MRDS Windows

[RJ]

I'm pondering a group update to the MRDS QRCs to include the "shapes" on the upper right side of the flip of the card. That'd be a lot of work, but might be worth it long term as it is perhaps more useful than what I have in there now (a bunch of screen grabs of the reticle shape.) Another hmmm...

I did some prototyping on what this might look like by amending a typical MRDS QRC (COA in this case) with this info. Screen grab of MRDS QRC for COA at (prototype) Rev 16 below.

On the "B" side, instead of repeating the optic name in shadow boxed 14 point bold, Rev 16 cards would instead have the optic name, dot color, MOA, and aperture, in 10 point non-shadow bold, to the left. The low-res screen grab of the optic currently on the right would be replaced with a simple rounded box to represent the aperture window, in "actual" size.



There are 70+ QRCs posted on the web site, so this would be a fair bit of effort. But applied across the board, it would give I think a bit more useful info about the optic, in terms of the dot, color, and aperture than what I have in there now.

I like it. Thank you for all the effort this takes!

All values are width x height in inches.

Is the COA window really smaller than an EPS C or SCS Carry? That's surprising, given the size of the optic...

Aimpoint says it’s 15mm x 15mm…15/25.4=0.591, so…yeah.

Thank you RJ.

That is disheartening. I have a 509t on my well worn and born again Gen 3 19. But I have a Gen 5 just waiting for me to decide how I want it cut.
I was hoping for a few more innovative designs, possibly, to come out the first of this year and was pretty stoked about the COA. (I am still stoked about what seems to be a pretty darn good mounting solution).

Your comparison chart is truly helpful RJ. I am very comfortable with the size and clarity of my 509t and might just stay with that optic for my G5.

Decisions, decisions...

Ok, I made a start at a process to create all the needed graphics for the MRDS to reflect "window" size. So the text is easy, that's just the optic name, MOA, color, etc. The tricky part is how to draw the dot. More specifically, what size do I draw them at?

Here's a start at two I'm working on, the COA (since it was on my mind) and my HS 407k GR, which I have here at my desk.



I'll leave out the mathematical mumbo jumbo (*) I used to arrive at the dot sizes, but these "windows" are scaled to actual size on my drawing tool...so how the dot looks in the window "should" in theory be correct.

I dunno. I am sitting here looking at my 407k, and can't quite get past that my drawing looks a little small, relative to the actual dot I see.

I don't have any other dots handy, but if someone has one, with a single MOA dot (or a multi reticle, I guess, like a 507c), that I can add to these two, can you let me know? If so, I'll build a dot picture, then ask you to look at your dot, and tell me, do you think it's "the same" as what you are seeing?

(I dunno if anyone has a COA, but that would be another one to try).

* I can post the math stuff, but I doubt anyone's interested.

I have calipers, and can offer:

RMRcc both 6 and 3.25 MOA
RMR 6 MOA
ACRO P-2
Romeo X Compact Enclosed 6 MOA
Romeo X Compact Open circle dot
Romeo X SIG-LOC circle dot
Steiner MPS

Ken, Awesome! TYSM! Let me pick one of those to draw and I’ll post back in a day or so for you to eyeball.

Reason I’m being particular about this is if I can do this mathematically, then all the 70+ MRDS QRC updates will go a lot faster.

Right, so four of the optics have been prototyped for the "new" look. These represent the largest and smallest windows, both red and green, with single and multiple reticle dots. So a representative cross section.

On the right is the existing graphic I am using for Rev 15 and prior. To the left is the proposed replacement for Rev 16, consisting of new text with the optic window size and other info, as well as a new graphic drawn "to scale", for lack of a better word:



If you have one of these optics, please could you eyeball it and tell me if the reticle looks like a reasonable approximation of what you actually see with Mk I eyeball?
