NEW Aimpoint Micro R-1 $299

I wonder if this is what he meant for 32 dollars at PA.

I believe he meant this:

Note that the aimpoint T-1/H-1/R-1 sits a little lower than the PA micro dot.
ie. on the Larue mount that everyone has, The T-1+Larue mount makes 1/3 cowitness. The PA+Larue mount makes NO COWITNESS. The PA+PA Riser makes a 1/3 cowitness. I don't now what a T-1+PA Riser would make. Maybe absolute cowitness. Regardless, I've read that the PA Riser linked above has a release lever that isn't amazing, but it does the job.

here's some info

never heard of a lower 1/2 co-witness but if you plan on doing that you might as well run an absolute co-witness which I don't think PA makes (but I could be wrong). Adding a spacer to a Laure Tall mount will make the iron sights disappear completely and at that point just use the lower 1/3 co-witness and throw away your irons; if your dot goes out you are screwed especially if your mount is non QD. Mine is on the way along with my Larue Tall mount I know that My avatar is Larue and I'm not just posting this to spam his products here (I have no affiliation). I think you should choose either or but do not try to achieve a "1/2 lower co-witness". Here's why I went with the tall mount but it's up to you...

The LT660HK is designed to provide lower-1/3 cowitness for the HK416 (and other piston uppers with raised flat tops). On a conventional flat top, the irons are a slightly too high as seen thought the LT660HK.

So, why Lower 1/3?
We get asked this all the time. The short answer is...it was "by request".
The long explanation is, it's really all about reducing clutter, and always being ready.

Our Aimpoint and EOTech mounts are optimally designed for weapon systems that run with fixed sights or BUIS's deployed in the upright position. Since it takes time to deploy flip-up irons, we here at LaRue (and many instructors) recommend you operate with the irons upright when possible. Chances are, if you actually need your irons, you're getting pretty busy, with at least one threat occupying your attention. Keeping them up, but out of the way, is the best of both worlds. Our lower-1/3 design keeps those irons out of the way, until they are needed.

Clutter in you field of view (FOV) isn't a good thing...with respect to the popular T1 micro, an upright rear sight can optically cover roughly 50% of the FOV. You can cover the front of an Aimpoint all you want, and still use the sight (keeping both eyes open), but covering the rear obstructs both target and reticle. (see the pic below).



Years ago, I was at a carbine class where the student next to me was noticeably lagging-behind during the live-fire drills. The instructor asked what the issue was, he said he was having problems "precisely lining-up the irons with the EOTech reticle"....and the cluttered view made it "hard to find the target". He wasn't super slow, just slightly slower than everyone else. After we removed his irons, and he almost instantly shot faster when given an unobstructed view, and began using the reticle the way it was intended. It wasn't the last time I observed this behavior.

"What about my cheek weld?"
Well...cheek weld is one of the most important factors that provide successful results when precision shooting. Especially when using high-magnification...We make several different mount heights for rifle scopes that keep that issue in mind.

That being said, cheek weld with a non-magnified red-dot optic (like an Aimpoint or an EOTech) is marginally more important than proper cheek weld with an aiming laser. Generally speaking, if you see the reticle, you're operational. Most people find the cheek weld with our mounts for these optics to be more than adequate, and the shift to the lower 1/3 for irons is minimal and intuitive.

Keep in mind, Aimpoints and EOTechs are intended to be used while in a variety of firing positions, many of which have little, or no cheek weld. If you are concentrating on cheek weld too much, you are not using the technology to it's fullest.

Even when you use the lower-1/3 method, the dot can be used "centered" in the tube. When both irons and dot zeroed, you can hit any target you can put the dot on, anywhere in the viewing area...independent of the irons. When you shift your eye position to the irons, the dot will follow (unless you turn the unit off).



As you move your head, and keep the weapon steady, the dot will not move. That's the beauty of a red dot (like Aimpoints and EOTechs)

The red dot and the Irons work completely independent of each other. It's a common misconception that you need to center the red dot and the irons in the viewing area.

You can verify the zero of your red dot by lining it up with your irons (or vice-versa)...but as long as you can see the dot anywhere in the viewing area, you're ready to take a shot. I know, I know, putting the dot nearer to the edge of the viewing area causes some distortion.

Another illustration that reinforces the advantages of a 1/1 red dot (like this Aimpoint CompM4)
If you can see it, you can hit it.

My apologies. I meant absolute cowitness. I was a little, err, impaired when I posted that, and in my mind, "1/2" was just half way down the sight. I'll correct that.

good info Isaiah thanks!

[till44]

Thanks for the heads up, they still have a few.

[crackerman]

I jumped on the deal so you should all go and get yours

[iano1]

Got the last one!

[iano1]

J/k about the last one... But I got one

[Isaiah4Autumn]

Got the last one!

J/k about the last one... But I got one

I was about to say...good thing you confessed. I called them yesterday and they still had 600 left...such a great deal

[only10x]

too bad I dont need one

[BiggSean]

Ugh, I was going to buy an Eotech clone for my GSG-5 ($100), but this seems like it's too good to pass up.

What do you guys think? Over-kill on a .22 plinker? haha

[The Bacon Eater]

I would buy one, but dont need another optic now. Great deal though

Of coarse not- because you can always transfer it to something else later if you like

[kahai808]

i gotta get one.
