Ok confused now. Bota-CS1 asked if the dot is too big. Does the 4MOA have a bigger dot than the 2MOA? I was asking for my setup, is going 4MOA too high vs 2MOA?

4 moa dot is bigger than a 2 moa dot
it depends on how far you are going to shoot and degree of accuracy you want
50 yards and in, not gonna make much difference
100 yards and out, it's gonna make a difference

100 yards and out, it's gonna make a difference

to be more clear, a 4 MOA dot will cover 4 MOA
for example, it will cover 4 inches (approximately) at 100 yards
whereas a 2 MOA dot will cover 2 inches at 100 yards

..., and the parallax is like 1 inch when your under 15-20 yards how often are you shooting at that distance and I'm pretty sure you can still hit a human target if its only 1 inch off if your way off to the side when looking though the glass.  It's pretty much on target if your cheek weld is on.  I mean a red dot is not really meant for precision.  its to shoot multiple human head sized targets quickly.  If you need that type of accuracy, get a scope!

Are you sure you're talking about the right red dot model?  Even Amazon says in it's description that the vortex is parallax free...

Keep in mind that a smaller dot doesn't equate to "better accuracy" same thing with a front sight post.
If you have to struggle to focus on that dot or post, you probably need a fatter dot or post.
I switched from .052 front sight post to a standard GI post .070 and my scores improved with less eye strain. It is documented amongst a lot of aging shooters as well. If you are off call with shots in the corner, you probably are not focusing on the front sight or you can't focus on it before you press the trigger.
No optic is 100% parallax free at all distances.

Well this would be more for 100yrds and out. which one would you guys go with, 2 or 4MOA?

if your gonna be shooting 100yrds and out I would go with the 2 moa the dot will cover less of the target

I think I'm just going to stick with the Aimpoint 2MOA as it's about 2 ounces lighter. Every little bit helps. I just need help with the iron sight now.

The Magpul Mbus Gen II's are pretty light as they come.

Neither; if this is going to be a designated 90+ meter rifle, I would personally lose the thought of a red dot and go with a variable power scope.

I do like those barrels, they start off as Shilen blanks.  they are chambered for .223 though.  careful about using 5.56 in them.

sub-moa guaranteed... 

Rainier makes them in 5.56 as well. The mountain, select or match series. I picked up a select for my build, seriously nice, plus flat rate shipping $7.95. got my barrel in 5 days. NiB BCG arrived in 3, also very nice.

 

Heavy sigh.

I'm just like John Lennon watching the wheels go round and round.
I take advice from whomever I can. From people wearing all kinds of tabs, medals, and assignments to units. Some advice works and some don't. I had a SGM who was a long tabber and went to SOTIC tell us that before he took a shot he took a gulp (as in swallowing) of air. Worked for him, didnt work for me. Not sure if he was just messin with us as we were just LTs trying to run a range at the time.
I think RDS are underestimated at the kind of work they can be used in. I was humbly shown that a 4 MOA RDS can engage targets at 400 meters. Fundamentals rule over gadgets and perceived performance. I like shooting HP because the targets don't lie. I've pounded concrete many times in frustration until I found out what the problem was - and it was always a principle of fundamentals.
Don't underestimate what a plain AR can do.
On the other hand, the modern AR is akin to a Mr. Potato Head.
You can dress it up to reenact a wet dream of killing zombies or hunting tangoes.
Whatever you want to do to it - do it. This is 'Merica The AR is an icon of freedom.

Ren and I are not really long range shooters, we are service rifle shooters. 200 and 300 yards are considered short range and targets are given the NRA SR and SR-3 designations. 500 and 600 yards are considered mid range and targets are given the MR and MR-1 designations.  We rarely shoot beyond that due to range availability and access to accurate downrange feedback.

The big question is what do you want to do with the AR?

Shooting milk jugs at 25 yards is much different that shooting mongooses at 200 yards. Red dots are great for minute of man sized targets out to 400, but will blot out a rat at 100. Variable scopes are good for the majority of situations. Iron sights are classic and should be included on every build since batteries die and glass breaks.

Like Ren said, Mr. Potato Head.

If bling is your thing, go ahead. Rails, bipods, lasers, gangstergrips, redimags, flashlights, and ceracote in designer colors.

If good shooting is your thing, then use a decent lower, 18-20" barrel. 1/7-1/8 twist, good trigger, sturdy sights adjustable for windage and elevation, and at least a red dot and a variable power scope to be changed as needed.
Spend money on quality ammo and test for group size and bullet drop and wind resistance at different ranges.

Learn the techniques of the winners of actual competitions. Many of them write books and have videos. I stay away from most commercial tactical schools. Most of their expertise is separating you from your money. And I don't see many of them shooting on the national circuit.

I'm here to have fun and not preparing for war or competition. But if SHTF I figure I'll use my bullpups for close range 100yrds and below, AR for mid 100 to whatever is mid, lol, and my bolt action for long distance. IDK? No need drama as everyone is entitled to their opinion. All I care about is an AR-15 for my wife to play with but something light.
