Im going to buy a Vortex sight for my Ar very soon but im not sure if i want the Strikefire 2 or the Sparc ii. The Strikefire 2 has a 4 moa dot size and the Sparc ii has a 2 moa dot size and thats where im stuck at. So tell me what you folks think. On an AR platform rifle what size moa do yall like your red dot sight to be?

I like my red dots to be 1MOA, whether on ARs, pistols, shotguns, whatever. As long as I can readily see the dot, I don't want it to subtend any more of the target than necessary. I can pick up a 1MOA dot just as fast as a 7MOA dot, and still shoot with greater precision on slower, more deliberate shots when circumstances warrant. This is why I like the Trijicon RMR LED version; it's available with 1MOA dot.

Between those two, I'd choose the 2MOA, all else being equal on model comparison.

But, that's me.

On an AR, I imagine smaller is generally better.  Unlike a pistol or shotgun, your engagement distances can be pretty vast, and your targets can seem mighty small.  I imagine the extra bit of precision would be worthwhile.  It's one reason I love the Eotech reticle so much, nevermind the egregious weight and battery life, which kill the sight for me.

Your last sentence got me to thinking more. I went back and did a side by side comparison of the 2 sights and while between the two there was everything i wanted in a red dot sight they neither one had the features i wanted by themselves.
At the moment i am looking at many many others. Thanks for triggering my mind to think again

The large 4MOA dot is why I sold my Strikefire 2 and bought a 1-6 scope with illuminated reticle.  The dot in the middle is 0.5MIL or 1.8MOA.  If you are only considering the 2 choices given, I'd choose the Spark.

I much prefer 2 moa dots vs the 4.  I prefer the smaller aiming point for precision.

Take a look at Holosun red dot sights.  They have quite a few models now with different dots and reticles.  I have had one for a while now and I really like it, for $200 its is fantastic.  I have a Sparc2 and IMO the holosun is better in every way.  They also have a 5 year battery life similar to Aimpoints.

I have been looking at Holsun and Sig Sauer ALOT. Especially since i realized neither of the Vortex sights had all the features i wanted. Im leaning towards the Sig Sauer Romeo5. It has a 2MOA dot, brightness settings which are night vision applicable, motion activated power on, 40,000 hour battery life and it comes with extra mounts for different applications like co-witness an AK or an AR. Holsun has pretty much the same features also but OpticPlanet is selling the Sig for only $149.00. Hopefully the sale will last til payday on the 1st, LOL!

Sigs are Holosun, so same optic except for cosmetics.  $150 is a good price.

In the same size, etc of Sig and Holosun, also consider Hi-Lux MM2.  On the Vortex side, the sight to look at is Sparc AR.

I have a lot of hands on time with all of these and like them a fair bit.  The choice sorta comes down to what you like. They are all related designs. 

If it were my money, I would probably be looking at the MM2: https://swfa.com/leatherwood-1x20-mm-2-digital-red-dot-sight-1.html  since the way the riser mount is set up, I have the least obstructed view.

On dot size: for distances where I use a red dot, both 2MOA and $MOA works fine.  If you have astigmatism, the dot might look a little sharper when it is larger, so make sure you get some hands on time with the sights.

If you decide to spend a little more money, I am testing Shield SIS right now and it has a lot to recommend itself.  It might be the most rugged red dot I have seen yet.

Koshkin i did not know Holsun and Sig were the same company. I did notice the similarities in the two but thats all i did.
I checked out the Hi-Lux and the Shield SIS also and they look great. Still i think im going to get the Sig Romeo5 since it has every option that i want in a red dot except multiple reticles. I do like to have a choice in reticles and really like the ones with the outer circle and an inner dot but its not a deal breaker for me. I may change my mind if i find one with all the options of the Romeo 5, multiple reticles and a decent price. Either way im going to order mine next week.

Aimpoint does not need to have the red dot centered in the field of view.  If the dot is on the target it is correct. Its a patented system that works very well.

All reflex red dot sights work that same way.

They are not the same company.

Many companies use the same OEM.

I Have a couple that do NOT. They may now but they did not do that 10 years ago.  You can lay one on something solid move around behind it and watch the dot shift from one location to another as your head moves. Centered they are consistent not centered they are off.

Shopping for a red dot sight is worse than hunting your wife a Valentine gift. You see hundreds of em with some of the features you want but none with all the features. Well thats not quite true since ive ran across several with every feature i want except build quality. It appears alot of the cheap sights are packed with features but i dont trust their ability to hold up over time.
Heres what i want in a red dot sight.
Tube design
red/green color choice
dot circle and dot reticle
1-2 MOA dot size
Night vision compatible
co-witness capable
lifetime warranty
a price below $300
I dont think thats too much to ask. I did find a very good deal on Holsuns PARALOW HS503CU for $189.99. Its usually advertised at around $280. Heres that link if anyones interested.

I have no first hand experience with the solar holosuns. But i have read when shooting from a shaded or darker area into bright areas it is an issue. They are to dim. They adjust brightness automatically based on the light the optic is sensing.

I also read that can be turned off and set to manual. Might be something you want to look into more though.

I read probably the same article which you did on the Holosuns. I kept looking and finally found another which said the auto brightness can be set to manual if desired. I dont know which one ill buy to be honest. Looked in to a ton of different sights lately. Heck SunOptics has a pretty decent setup to but then so do so many others. Thanks for the input though

My StrikefireII is only parallax free after 50 yards. The newer Sparc is totally parallax free,not sure about the other sights being discussed in this thread.

Over the last week or two ive read up alot on red dots and quite alot of that concerned parallax. I may be wrong but heres the way ive came to understand it. None of them are actually parallax free. They just have such a low rating they are considered parallax free and are ranked accordingly. This article in WIKI explains it as good as anything else ive read.

I'll probably concede the 2 MOA dot is "better" for more precise bullet placement, I'm keeping my 4 MOA Aimpoint T1 for a spell longer. I always thought it was more of a 3 MOA dot any way. Seemed smaller too me than the former Comp M2's I ran. 

Turning the intensity down a lick helps reduce target obstruction, IMHO.  Wink

I agree about the parallax. I have owned aimpoint, trijicon, vortex, holosun. I can see parallax error in them all. Some more than others.

cheaptrick if i had an Aimpoint id keep it to, LOL.
Ive been thinking about going the other way also. Nikon has an AR kit with a 3x9x40 Matte BDC 600 scope, P series AR mount and (oddly enough) a spot-on wind meter for $249.95. Even if i decide to later get a red dot i like the scope for my Weatherby Vanguard 223. Then again i have several scopes laying around unused now though they are pretty old. Guess im just like everyone else and like new toys.

Well after alot of thought and hee hawing around i ordered the Athlon Midas BTR RD13. It doesnt have the red/green choice nor multiple reticles but it did have a style of circle dot reticle which i like alot. The price wasnt to bad either.



I know i spoke about the Nikon 3x9x50 kit. Well i figure next month ill get myself a new scope but im gone check out alot of different ones before i buy.
