Hey guys I'm about to buy a red dot sight and can't seem to chose between closed (scope looking) and open (lens is on one side of the base)

What are the pros and cons to each style???



Open or Closed?


EDIT- Couldn't get links to work but the idea is



VS

I don't think it really matters either way. You'll shoot with both eyes open anyways. The tube-type might be easier to clean.

Both types of sight work fine.

In my opinion NC Star sights should be avoided at all costs.  I have owned/used both of the ones shown in the original post.  The open style one is very ruggedly constructed, but the dot (even at the highest setting) is not quite bright enough to be used easily in normal daylight conditions.  The closed style one has a brighter dot, but is very cheaply constructed.  Mine did not survive the first hit by a paintball that it took.

I personally prefer BSA red dots.  http://www.bsaoptics.com/scope.aspx?product=87 - This one has 22 style dovetail mounts which means it will fit most unmodified Tippmanns.  Note that they can often be found cheaper at places like Wal-Mart.  I also recommend that if you get one of these you get a see-through lens cover as well to protect your investment.  (I have had the plastic shot out of my lens cover three times.  Being cheap, I just keep replacing it with a piece of plastic from a piece of bubble packaging that I saved just for that purpose.)

Edited Addition:  Oops . . . forgot to address the pros and cons of each style. 

Downside to the open ones is that you can get paint on both sides of the lens and, depending on how far recessed the lens is, the back can be challenging to clean without the proper equipment.  Paint can also get into the laser emitter aperture and block the beam that makes the dot.  Neither of these are issues with the closed ones.

Downside to the closed style is that if moisture gets inside them you can have internal fogging problems.  This obviously does not occur with the open ones.

the second one you have posted looks almost exactly like the one i bought yesterday!!  i dont like using the ones with only one lense.  i get better sight acquirement withe the scoped ones bro.  but thats just me.   im pretty accurate with mine.... but trust me, it will be "different" once you put the scope on your marker.

I have a core red dot, which works great.

I got hit directly on the lens last game, from about 15 feet away. It survived without a problem, although there is still a bunch of red paint all around it now... I need to clean all my gear.

It's not actually a "scope" unless it also provides magnification . . . and magnification is pretty useless for aiming in paintball.

its not you idea of a "scope"  and it is a red dot 2 lense scope.   scope emplies the whole "2 lense" deal.  i use a   RED LASER DOT 2LENSED SCOPE

wow.  someone needs to work on their reading comprehension.

no matter what YOU want to call it, it's not a scope unless it provides magnification, which I'm assuming it doesn't, because in your next post you say you agree that magnification is pointless.  


learn to read.  you have a sight, not a scope.

Again, reading comprehension.

 

A red dot sight (also called a reflex sight or, for certain models, a reflex scope) is a non-magnifying firearm sight that uses an illuminated reticle, typically in the form of a red dot.[1] It can also be found on telescopes and point and shoot digital cameras that have electronic viewfinders. Red dot sights should not be confused with laser sights, which project a small red dot on the target.

Seeing as the word "scope" was only used once in the whole article, and wasn't used correctly, as wikipedia can be edited by anyone that's intelligent enough to make an account, which doesn't necessarily make them intelligent enough to KNOW anything, I didn't think it all that important, so I left it out.  If you can find the word "scope" anywhere else in that article, and it be used intelligently, I'll be glad to retract my previous statements.

The long eye relief possible makes red dot sights appropriate for firearms with heavy recoil that might drive a conventional short eye relief scope into the shooter's eye; one example would be http://www.answers.com/topic/shotgun" class="ilnk" onclick="assignParam'navinfo','method4'+getLinkTextForCookiethis;" target="_top - shotguns used for hunting http://www.answers.com/topic/turkey-bird" class="ilnk" onclick="assignParam'navinfo','method4'+getLinkTextForCookiethis;" target="_top - turkey .

Red dot sights are also used on telescope sights.

From http://www.answers.com/topic/reflex-sight - this location.  Note that the first bolded section specifically defines red dots as lacking magnification and the second bolded section explains for which "certain models" it would be appropriate to refer to a red dot as a "scope."

http://www.opticsplanet.net/red-dot-sights-guide.html - Opticsplanet.net also provides a fairly accurate primer on these sights:

http://www.opticsplanet.net/red-dot-scopes.html - Red dot sights are almost always zero power, or one power. Same thing. This means they do not magnify. A http://www.opticsplanet.net/red-dot-scopes.html - red dot sight is not for precision shooting, but rather very close or very fast shooting.

Chuck Hawkes (amateur astronomer, professional photographer, camera store manager and photography teacher) also provides a very informative article at http://www.chuckhawks.com/optical_sights.htm - this location.

Electronic "red dot" sights have become increasing popular for handguns. Most of these look like short, fat, long eye relief telescopic sights, but have no magnification. They use battery powered electronics to project a red dot at the point of aim, centered in the optical tube, where the crosshairs of a conventional telescopic sight would appear. Red dot sights usually have conventional turrets with knobs for adjusting the windage and elevation of the sight, again similar to a conventional scope. Some red dot sights have dispensed with the tube altogether, and consist of a base with the optical and electronic systems necessary to project the red dot in a sort of "heads up" display. Most red dot sights come with rings, and mount by clamping to conventional Weaver-style scope bases.

The red dot sight's optics put everything seen through it (red dot and target alike) in the same optical plane, again just like a conventional scope. The long eye relief and zero magnification make it unnecessary to focus a red dot sight.


Note the comparison to, yet differentiation from, magnifying "scopes."

If you're concerned about paintball breakage, go with an ADCO since they'll replace one if it get's broken with a paintball hit. I got the sure shot(tube style) with an 8 MOA dot, which is about twice as large as normal red dots, making it great for short range. 


Posted By: Mack

^^^ All good points.  ADCO does warranty against paintball damage and while an 8 MOA dot is useless for long range with a real gun it is perfect for what we do with paintball markers.

My only problem with ADCOs is that I like to set my point of aim slightly below where the ball would hit if it had a straight trajectory (to semi-compensate for the arcing trajectory) and the two I had would not adjust down far enough for my liking.  As redneck sounds like he has more recent experience with them than I me, perhaps he will weigh in again and let us know if this is still an issue.

With or without a sight basic marksmanship comes into play.  Mounting a sight on your marker doesn't make you Dead Eye Dick all of a sudden.  You still have to learn how to shoot.  I have two Laseraim Illusion red dots and love them.  Tube style, very durable, very bright.  I don't always use them but there are times when they come in REALLY handy.

As far as which one to get, I like the durability of the tube style red dots.  I'm a clutz and generally fall at somepoint during just about every paintball outing.  :)  With my clumsy azz whatever I have on my person better be milspec quality when it comes to it's ruggedness.

I found this interesting. It gives you an idea of what range to establish a battle sight setting so you're shots aren't too low/high out to your maximum engagement distance. Also doubles as a handy BS dectector for tales of long shots. http://www.handloads.com/calc/index.html - calculator

Enter your muzzle velocity(270-300fps)
ballistic coefficent of .01
weight of projectile 49-50 grains
your sight height(height of sights above centerline of bore, about 1.5" for a 98c)

The rest of the data is yours to play with.
