I’m new to ARs so don’t judge. But how do some people have optics and iron sights on their ARs at the same time? Wouldn’t that obscure sight picture from the optic with the iron sight? Look at the picture below his Irons and optic are on the same sight plane???

Look up co-witness

Red Dot Sights and Co-Witnessing: What's it all about? (Video) - Guns.com

Co-witnessing, or using both your red dot sights and iron sights to double verify the target, is not that difficult to do and really not all that necessary.

Co-Witness Sights: Absolute and Lower 1/3 [Ultimate Guide]

What's a co-witness sight with a red dot? What's the difference from absolute vs lower one-thirds co-witness? And how to do you zero a co-witnessed optic?

[Square target]

That look like a red dot which just shows a illuminated dot when turned on to aim with. When it's off it's just like looking through a straight tube so you can use sights if lined up with the tube.

 

[Yosemite Sam]

Speaking of which, my upper came with BUS. My red dot was advertised as being lower 1/3. I couldn't see the BUS. So I bought another rider from Amazon I got today. Now if my red dot goes out, I can use the BUS.

 

[GunYankee]

I really like the Sig Romeo 7. Does anyone know if this is 1/3 or absolute co witness with A2 height sights?

 

[Russ D]

BUS might be important, if you are a long long way from home. If my optic goes out, I just go to the house, and get another rifle.

 

[Yosemite Sam]

Anticipate the worse, hope for .......

 

[Stamps6]

I have a variable tactical scope on my AR. I also have the A2 front sight and it can’t be seen in the scope. I took off my pop up rear sight and I even have a carry handle already sighted in ready to be put on. I know I’m not going into battle. I shoot ground hogs and fox/coyotes and wouldn’t need those CCB sights for the most part, ever again. I’m not going to march against some enemy invader.

 

[Palancar]

The only stupid question is the unasked question the way I see it. I myself also learned from this thread.

 

[Wag]

I got rollover BUIS. If the battery goes on the red dot, I just tilt the rifle 1/4 turn and I have sights again. Eliminates the need to remove the red dot in the middle of shooting. Kinda nice, actually.

--Wag--

 

[Yosemite Sam]

You mean the offset? That's a good idea.

 

[Wag]

Yes, they're called that from time to time. My red dot has a quick release but still, that takes some time and then you have to store it somewhere safe. Perhaps a pocket is good enough.

--Wag--

 

[Steyr Man 146]

Technique is referred to as "Cowitness" shooter has the "OPTION" of using either. Some set Irons for out to say 100 yards and the red dots to exceed 100 depends on shooter weapon capability and personal choice nothing wrong, as the distance changes red dots in picture or it is not, I found it annoying others adapt.

 

[Yosemite Sam]

I just don't want things sticking out the sides. My light sticks out on the left, they would stick out on the right, how do you lay it down????? Suck a dilemma. Looking through the tube is ok at the range, but in real world, especially in the dark, it's a problem.

 

[Wag]

Mine fold in on the barrel and flip up with a quick release button.

--Wag--

 

[Yosemite Sam]

Oh yea! Mine flip up, all I need is a couple offset rails. "A;; I need", "All I need", damn money sink. Two or three purchases ago I said I'm done, and every purchase since. And I'm not talking "budget", I'm talking "low budget". A collection of junk. Tomorrow, I'll see how my collection of junk performs. Can't wait.

 

[marcglock30]

I tried the co-witnessing thing, and it drove me crazy. I am just a ham and egger, and far from a Tactical guru, but I couldn't get it to work for me. I ended up selling my retail lower, and buying and building an 80% rifle kit and additional 80% lower for my original upper, and made one with open sights, and one with a 4x scope. Best of both worlds 😉

 

[ArthAnsgar]

I just keep a flip-up front post on my AR when I use the red dot. I figure if SHTF and my optics battery dies when I'm away from home, then I can use the optic tube as an impromptu peep sight. I don't use it at the same time as the red dot, though, never saw the point.

 

[Joker]

I don't have a red dot, but I have a Vortex scope and pop-up iron sights on mine. The iron sights are mounted on 45 degree picatinny rails. If that's not for you, I believe you can get a scope mount that sits high and let's you see the iron sights through it.

 

[Stubby]

My red Dot sits high enough that I can use the iron sites by looking through the Red Dot mount. I had to add the iron sites since my Ar didn't come with them. But that way I could pick up what I wanted instead of what someone else decided I needed. But I am changing the Red Dot next to something better next.
