I bought a Bushnel red dot sight many years ago when they first came out. I want to get another "red dot" but now there are also "holosights" and "reflex sights" etc. I don't know what these things are or what they are supposed to do, or even if they are any better than the original red dots.

Please educate me:)

Thanks
 
Well twelve views and no replies so it looks like I'm not the only dumb ass around here.:)

Does anyone know what a collimator sight is :confused:
 
I'm not an expert in these things but I'll try and answer your question. I belive red dot and reflex sights work on the same general principle: you look though them and see a red recticle (dot or other) projected onto your traget. They both give 1X magnification (none) have unlimited eye relief. Reflex sights are supposed to be very good at a fast target acquisition.

Red dot scopes are an older design, enclosed in a metal tube, and far less “tacticool” going for about $100-150. Eotech reflex sights are considered to be the best and go for about $500.

Edit:
Read wikipedia

If I understand this correctly a red dot projects a red dot on a screen in the sight, the reflection is what you see. There is more paralax in this type of sight. Turn the sight slightly to the sides and the red dot moves altering the point of impact. Reflex sights were designed on the same principle as the red dot but eliminated the "Scope tube" allowing the opperator to keep both eyes open allowing reflex shooting. Holo sights use holographics as opposed to partial reflection to project the dot usually 50m down range paralax is reduced by the dot appearing to be much further down range than a red dot. If you twist the gun unlike the red dot taht moves you lose sight of the dot in a holo sight.

I may be wrong and I'm sure I'll get slamed if I am but this is what I understand.

It all depends upon who's terminology you are using.

The Bushnell holosights where manufactured by EOTECH (a joint CIA/US Gov't venture initially) They are vitually parallex free however they where not very robust.

When the US military became interested in the Holosight - EoTech started selling a militarized version direct and Bushnel sold a more robust but still not "milspec" version.

The Term reflex sight simply refers to the fact a dot is placed in the field of view on a vision screen either by projection or a fixed dot. However Trijicon makes a sight called the Reflex as well which is lit by both tritium and fibre optic.

The Aimpoints starting way back had the large tube red dots - getting progressively smaller and more robust - they have parallex set for 25m or 50m depending upon what model.

NONE of these sighting system project anything past the optic.

They are also refered to as CCO's (close combat optics), collimator sights etc.
 
IIRC the first time I heard the term "reflex sight" it was applied to a sight that one didn't look through. It projected a red dot on a dark background.

So you are asking how does that work as a sight when you can't see your target... You just leave both eyes open, so suddenly you have a floating red dot in you field of vision. It was called something like an "Occuded Eye Sight"

And again, IIRC, it was crap.
 
The Armson OEG's where the start of combat optics -- they where a lot better than irons for dynamic shooting. If you look at the pics of the Son Tay rescue team a lot of CAR15's had them... that was 1970

A lo of lessons where lost since the idea did not go much further until USASOC units started playing with Aimpoints in the late 80's.

Reflexsive sights are from reflexsive shooting - the idea is the weapn comes up and you immediate have the sight - looking at the tgt with the sight reticle superimposed
 
This is how I keep track of them:

Dot sight looks like a scope ie Aimpoint, Bushnell, et al
Reflex sight has a 'heads up' screen ie Cmore, Takko, Kobra
Holosight have a monitor where an image is displayed ie Holosight, EO Tech.

The best benefit of these sights is that where ever the 'dot' is in your field of view, that is where the bullet will land. You do not need scope tube/eye alignment as in a traditional glass scope (parallax). So by that definition, these lit optics are parallax free with unlimited eye relief.

Speed comes from not having to line up anything. Follow the bouncing dot.

I would think about 100 -150 yards if it was a peep site,and that is where about 90% of my shots are taken[actually, most game has been killed within 75 yards]
 
I liked them both. When I had an AR carbine .223, I was doing head shots from the ready on half sized man targets at 50 yards = 100y.(?) Very quick IMHO, much better than iron sights.
