[Gun Smoke]

A few months back I purchased a red dot from op and I do like it but got it mainly for the 22. Now that I have used it for a while I am thinking of venturing into a higher end red dot but am not clear on the differences between a red dot and a holographic site.

With that said I notice my red dot( low end paid $125) does not stay on target well. I have used an eotech wich is parra lax free meaning whichever angle I look from it will be true to where the dot lays. Wich is not the case with my red dot. Is mine just a pos or are all red dots have parallax ( problem viewing and staying true when viewed from anywhere besides directly behind it). If so it almost seems pointless why not just use irons?

The dot i use is co witnessed and I feel like when I shoot it I have to line it up the sites normally anyway. The only benefit I see is it would perform better in low lighting. Are all red dots require the same in this way? Is the eotech the only dot that performs without parallax ? What about the aim point? Thanks

As I replied to your other post...

Not trying to be a Jo but I think that's why he is considering it over the aim point. Similar performance but less durable for a fraction of the price. I have also been thinking about getting one but then I will just end up with 3 $100ish sight when I could have purchased 1 eotech or aim point that I would probably have for the rest of my life. So I'm at a stand still would like to try a few of these lower end ones out. I hear bushels makes a good red dot as well as primary arms.

Go with an aimpoint.

I have destroyed more cheap ($100 ish) red dots than I care to admit that I bought.

Its one of those things that you get what you pay for.

If you dont want to spend $650 on a CompM4, look at the "pro" or go used.
Most people wont use their rifle hard enough to make you loose ANYTHING by going used.

Makesure its not a fake and you should be gtg.

Your doing it wrong, the point of a co-witness is to make zeroing the optic easier. Once zeroed you can flipdown your buis. (depending on what your running this may not be an option.)

Gun smoke is asking about some of the differences in the reflex sights. He's not necessarily "doing it wrong" with the co-witness. Some people like "true co-witness" where everything lines up when the gun is mounted properly.

But he was more asking if the other red dots act like the eotech where the recticle is always on point of aim if you move your head. I.e. you can almost look around corners. In that case the iron sight picture would appear off, because the iron sights are only accurate when the gun is mounted. But the eotech would still be on target. He was mentioning that in his experience with red dots, they don't seem to have that "reflex" action so that to get on target the gun has to be mounted just like a scope or iron sights.

I was curious about this too. Which other red dots stay on target (appear to move within the optic as your head moves) regardless of the viewing angle? (gun smoke, by the way, I don't think the term parallax is the best way to describe this feature, although many good reflex sights also do minimize parallax)

A red dot, or sometimes known as a reflex, has the illuminated
reticle reflected off the rear side of the objective lens that
is pointed towards the targeting eye in which the source is a
low powered light emitting diode. The lens will have a special
coating that only reflects the light wavelength of the illumination
and allow all other light waves to pass through.

Although many red dots advertise that they are "parallax free"...
they are referring mainly to a specific distance using perfect eye
alignment. Even then, there still a noticeable amount of parallax
distortion. These type of sights also would require that you aim
with the lit reticle towards the center of your sight's lens to obtain
the best accuracy. The further the target, the larger the parallax
distortion. Longer tube red dots would generally give you better
accuracy over shorter tubes or open lens reflexes.

Red dots are more ideal for closer range shooting in most lighting
conditions. Quality red dots would've reduced much parallax but
never all of it. Many lower brands like to jump on this bandwagon
by making simple inexpensive sights which are virtually useless for
shooters seeking fast acquisition accuracy. Most people would
normally use one eye to shoot with a red dot.

A holographic sight floats your reticle in the target viewing area
from a laser emitting pattern. The lens do not filter any light
waves passing through it, your target view is unaltered except for
the floating holographic reticle that is superimposed in front of
it. Holographic apertures requires it to be mounted slightly
higher also giving you a larger field of view (FOV). Being more
advanced using laser imaging, holographic sights will be slightly
bulkier and possibly heavier.

The holographic sight is virtually parallax free because of its
ability to produce the "virtual" floating reticle to proper positioning
regardless of the angle of your eye's view. To obtain the best
holographic reticle you should use both eyes ignoring the frame
of the sight itself... since many holographic sights have the
ability to create 3 dimensional reticles.

The battery life on a holographic is very short compared to a
red dot/reflex. Also, holographic sights tend to not work as
well in very low or hot temperatures whereas red dots/reflexes
are not affected at all.

A shooter's eye will tend to place a red dot's reticle downrange
on top of their target whereas holographs appear to float in front
of their targets. This alone can be a deciding factor for people
that prefer one or the other regardless of the technologies.

Depending on your budget, decent red dots/reflexes & holographics
would be the Aimpoint, Trijicon, Vortex, Burris, Nikon & Leupolds
and of course... EoTech.

Hope this helps.

Peace,

Definitely aimpoint.  I would go with a T1 and a larue mount.  Definitely worth the money.  I have an eotech now but am switching back to an aimpoint... My eotech has failed me for the second time.  I had an aimpoint in Iraq and not once did it fail me or lose its zero.  Buy once, and it will pay off itself over your lifetime.

There are different height mounts that are available for aimpoints. Get the one that will be 1/3 co-witness with your irons. This way, you will get a benefit of both. You can also get fold down front and rear sights.

I'm not really a fan of the aim point and as stated bye bottomrock i am trying to clearly understand the difference between the 2 designs. Ghost very helpfully thanks even though I had to read a few things twice to understand them.

Thanks everyone for the help and opinions I will probably just get the eotech for now. From what I understand the battery (corrosion/ connection) issue's have been fixed in the new models and I like the advantages it has over the normal red dot. I am going to see if any friend have an aim point I can try out I would like to compare it to the red dot I already purchased and see how it performs in comparrison.
