Nope, red dot sights are used independently of your iron sights. That's what makes them so fast.

Depends.

Sight in your irons and sight in your EOTech. When you now look through your irons, the EOTech should be pointing in the exact same place.

In other words, if your irons are zeroed, then alligning your EOTech with your irons will be fine. It's called "cowitness."


Just re-read your question. And I think you mean actually using them. In that case.. no, you don't need to line them up. Whatever your red dot is pointing at is what you're going to hit. Try pointing at something and moving your head around. The red dot should "follow" your target.

I flip my front and back down when I am using the eotech... also, if the eotech is zeroed, you can flip back and front back up and zero the iron sights without fireing a shot

5150... nice.... they got you too

what is 417?

Many prefer using the Eotech WITH back up iron sights that are ready to deploy in case the Eo goes down. Murphy's Law

If you're in harms way, it's always best to have redundancy.

However, for most of us, the paper and steel plates don't shoot back. We have plenty of time to flip up our sights.

When any firearm is brought up to eye level, it must be ready to fire (excluding the safety) for me. Standard F-Marked front sight with a LaRue rear sight and a EOTech sitting in between is a winning combination for me. Don't matter if i'm punching paper or hunting.. it just needs to do what I want when I want. If the EOTech is dead or washed out because of bright or direct sunlight, I know my irons are right there w/o delay.

I like my E-Otech mounted so my iron sights are in the bottom 1/3rd of the window.

The RRA "Dominator" raises the EOTech on an M4 so that the BUIS is even lower in the EOTech window. Kind of pricey at $185 but includes the rear sight: see if your department will spring for it.

YHM makes a riser without the sight. So does LaRue. About 1/6th the cost for the YHM, 30% less for the LaRue.

How easy is it to acquire a target using the iron sights when you have a red dot sight mounted on a riser?

Depends on the red dot, the riser, and the iron sights.

An open red dot with a wide field of view and absolute co-witness makes it pretty easy to use the iron sights. The narrower the FOV, the harder it will be, and the further out of the center the iron sights are, the harder it will be.

I find using the iron sights with an absolute co-witnessed Eotech or Aimpoint is pretty straightforward, but with a smaller tube-style target red dot like the Ultradot, it's not as fast.

This question is a bit confusing. Are you asking how is it to use the irons through the red-dot, when the red-dot fails?

It's no more difficult than without it there. There's just the window of the red-dot.

With the red-dot on, you essentially ignore the irons. This is why bottom third co-witness is nice. If you align the irons, the red-dot sits on target. But if you get your cheek weld such that the red-dot is centered in the optic, you're about 1/4" above the irons. Remember, the real advantage of a red-dot is you don't need a good cheek weld. You can move your head, without moving the rifle, and the dot tracks the point of impact. That's what makes it so fast. The "sight picture" is just, "where's the dot?"

So a cowitness means an iron sight thats you can look at through the red dot scope, or an iron sight that sits below the red dot scope and allows you to see through under the scope itself because the scope is on a riser?

Co-witness means you can simultaneously look at both. It would be using the irons through the optic.
