Not sure how happy I would be if my new $2800 scope is exhibiting CA.
It's not bad but there is slight. Just to add that my brother didn't notice it by I seem to be extremely sensitive to it in optics. Not the first scope where I see it and others don't.
Show my a scope in any price range that doesn't have some CA in some conditions?
I had the same issue with that tier1 mount and throw lever. I can also confirm that the MKM lever will fix this issue. but if you can go with the pro series. It looks better and is more rigid.
www.mkmachining.com I already ordered the other. I didn't notice the Pro series. Is there a difference? You had to go and tell me......damn it.I had the same issue with that tier1 mount and throw lever. I can also confirm that the MKM lever will fix this issue. but if you can go with the pro series. It looks better and is more rigid.
March Pro Series Throw Levers
Upgrade your March optic with one of our March Pro Series throw levers, speeding up magnification changes and target engagements without breaking the bank. Our Pro Series Throw Levers are printed using a HP Multi Jet Fusion 5200 printer. This allows us to get the surface finish of a modeled...
The non-pro version has the obvious 3D printing artifacts due to FDM process. The Pro series has more of a finished look due to a different printing technology. Their sales page for the march lever has the picture of the pro series. It should look similar to this: https://www.mkmachining.com/product/athlon-polymer-throw-levers/#throw-lever-model

I will take 3 of them.
I have tried everything to get any CA out of mine, and I can't do it. May be I should try it again.
Every TT I have owned has had slight CA in varying situations. I’ve never seen any optic that does not. It’s just slight enough I don’t care, and I’m overly sensitive to it.
Yeah, they can. In many cases, it's very small and almost undetectable, in other cases, it can be significant. For instance, I mounted an NF NXS12-42X56 on my .22LR and took it to a rimfire match. It was a little sporting because the minimum distance for the side focus was 50(ish) yards. Anyway, I started at 12X and got zeroed in nicely. Then I cranked up to 42X and noticed that my hits were now at 1 o'clock, about 1 inch away. I was fascinated by that and wound the scope up and down several times to make sure I was not hallucinating or just screwing up. It was solidly reproducible, again and again.
I work with several people that are world-class experts on lens manufacture, and I asked them about this subject. This is what they told me:
True that, also only a perfectly built tape measure can be used to measure the exact diameter of an atom.
Setting aside the idea that an atom has an exact diameter (it doesn't), and that any measuring device can find an exact measurement (it can't), you can't use a measuring device (no matter how accurate/precise) with a smaller resolution than the object you are trying to measure to get any meaningful measurement. Since an atom is multiple orders of magnitude smaller than any tape measure resolution, it can't be done.
So does this mean you agree with me, or disagree with me?
Oh I am aware of that fact. Most of the people I work with on a daily basis are ESL so I quickly identify the situation, and understand the issues of translation that occurs. My statement wasn't any type of attack, just simply pointing out that a significant part of the article probably would have been better served if it had been a bit more spelled out. Nothing more.
Do you want to hunt at 100yds, or shoot steel at 1000yds? Those are very different things, requiring very different tool boxes.
Thanks for the comment. The gun (MDRX) is currently wearing a Kahles 1-8 with the 3GR reticle which I can take out to ~900 at the range (on admittedly large steel) without too much issue. It's an amazing scope; however I've found that the reticle's 1 mil subtensions are not quite fine enough for fine tuning shots on smaller targets past 600 and I run out of mils on the reticle on the further targets.
Only have 1 season under my belt so what I think is necessary is pretty theoretical/read off of internet forums at the moment. I live in the west where the distances are relatively far. I probably wouldn't take a shot past 300 yards though and chances of taking a shot at 1x are slim. I think the hunting part is just a nice to have, wouldn't be too sad to have a bit of loss of functionality here anyway.
They are doing it on purpose: https://marchscopes.com/news/5512/ . And that's another reason to love them. I wish more companies did that (not just the scope manufacturers but in other industries as well).
One thing to remember - virtually all March scopes are made to order. With the possible exception of their service rifle model, they are not kept in dealer inventory. The long range supply web site has more details on ordering, etc.
Europtic does keep a few in stock, but not many.
I just picked one up from Euro and they have a couple more as well as their sister company Scopelist. Scopelist actually has a good deal, which Euro will honor, where they discount the taxes and free 2 day shipping.
dammit, that is why i want one, but still considering less expensive options. i just swap different optics on it for now.
Thanks. the only change I want to make is the barrel. Faxon is the only 12.5 option right now in 6 ARC. Hopefully some other manufacturers will come out with some shorty options.
