View Full Version : Backup optic with LPVO: RMR or Aimpoint?
I am putting my LPVO together for my new rifle and purchased the Badger Ordnance mount, and am nothing guys using Trijicon RMRs and Aimpoint T2.
What are the pros/cons of using an Aimpoint or RMR as a back up sight?
I was told that our eye is drawn faster to a circle vs square.
Any thoughts/advice?
RMR: smaller and lighter, easier to mount on a ring cap or tube (doesn’t apply to your stated use though)
Aimpoint Micro: everything else (battery life, window, possibly durability, UI, battery changes, enclosed emitter)
Neither is a bad option but IMO, if you can swing the cost and the extra couple of ounces, the Aimpoint is more optimal.
I plan on getting a Holosun 509T to use on my Arisaka offset mount, as soon as they become available.

But it's from China! Seriously, it's cheaper because of slave labor.
The t2 is better in every way except weight.
I would go with the RMR just because it's so much smaller.
My opinion, which is worth zilch, it depends on how much weight you are willing to give up.
An LPVO plus mount plus offset mount is going to start adding up.
The RMR will save you a few ounces, which add up.

Has anyone heard about this study that shows that the human eye is drawn more readily to a circle, than a square?

Aimpoint ACRO is getting more popular as a secondary sight now since it's smaller than the Micro.
But then there is the circle or square thing....

But then there is the circle or square thing....Pretty irrelevant, given that the differing usable window size of the RMR and the fact that it's an open sight makes any comparison to the Micro a moot point on that front.
The point being: I heard/read somewhere that there has been a study that indicates the human eye is drawn more quickly into a circle, than a square. The Aimpoint being a circle, the RMR a square.

If you were comparing two sights with fairly similar specs, then application of that conclusion has merit, but when you're comparing sights with noticeably different usable window sizes, different housing configurations, and different optical properties, there are far more other factors at play that will impact how quickly the user will be able to quickly and consistently find the dot.

PT MCcain, is that you???

Don't think that's how a red dot sight works.

Using my brown belt in Google-Fu I found this, not exactly the same thing, but it does make the same point: https://www.webdesignerdepot.com/2012/11/stop-being-so-square/
The eye is drawn to circles and the information contained within, and they are faster and easier for the brain to process than hard-edged squares and rectangles.
I have a T1 in Arisaka offset mount combined with a k16i. It’s great. I like the RMR, I just like the Aimpoint micro series better.
Pretty much not helpful and totally missing the point, but thanks.

You’re asking about nuanced details in optics and mounts - things that don’t lend themselves to internet “research” and are best determined by your own experience. Further, as another poster mentioned if you think a rectangular vs circular optic housing matters in a unity power optic, you’re not understanding how such optics work.
The RMR and Aimpoint will both serve you well. The RMR is lighter. It may be a bit more cramped to activate the illumination controls on the RMR in a badger C1, but this is speculation on my part because I don’t use that mount and instead have my LPVOs in G mounts, with AD offset mount for the T1. Also, you’ll have to remove the optic to change batteries, which in theory can lead to a need to rezero, in practice (on a pistol) does not seem to be an issue.
The T2 will be heavier than the RMR, but the illumination will be easier to actuate. The T2 battery change is also easier and doesn’t require optic removal.
YMMV. I long ago stopped “researching” my optic and mount decisions before purchase in favor of buying, trying, keeping or swapping based on my personal experience in using items.

Yeah, PT MCcain.

He knows this, everything is just expensive so he's trying to figure it out before trying. We all get it, and it sucks.
The RMR... you’ll have to remove the optic to change batteries.
Shameless plug: Not always....

OK. that is pretty cool but for 2 and half bills it is too cool for me.

Ha ha, don't worry, we were told this is not patent-able, so sooner or later someone will "borrow" our idea and put that on a cheaper (non-titanium/non-adjustable) mount.
(Unless we knock off our own idea first...???)

I’ll stick with Arisaka for offset mounts.
