Does Co-Witnessing Red Dots with Iron Sights Work?

I use a 36yd absolute zero. I do the same thing with my irons although min are us ally folded out of the way. Cool video and channel.

I cowitness all my pistols and AR pistols.

I thought co-witness meant you can see your back up iron sights through your optic ? If you have a absolute co witness than the dot would be equal to the front and rear sight but if you have a lower 1/3 co witness, than the dot DOESN’T align with the iron sights.

Thanks Boss

Have romeo 8 and Romeo 5 both co witness with flip up front and back sig irons and it's works great. Np clutter at all just flip em down. Still have room for Juliet 3 magnifier too

So I was always told in the army that your irons are set to 300, and your dot is only good to 250, do you need to adjust your iron zero to cowitness at range? or is it just keeping a mental note or were my rifle instructors just not very bright?

I'm glad Dorr still uses a GPS grip pod. I have one but people make fun of me for having one 🙃 lol

My first Aimpoint was the Comp ML2 haha I loved that red dot. I’ve now been using Vortex Crossfires and so far no issues. Love the price, weight and performance. Another good one Dorr!

why would you want half your red dot sight picture obscured ??

I tried cold witnessing with my Romeo 7 and it just drove me nuts, got rid of the flip up site

Cool knife

There is no light transmission through a medium (e.g. glass, etc.) without some degree of refraction. If your irons are zeroed without the red dot mounted, POI will shift simply by adding a layer of glass between the front and rear sight.

Is this more effective than canted BUIS?

I have a similar setup except my rear site folds down which I think is preferable. I leave it folder down because it's less clutter, but it's there when you need it or if you want to check zero.

I’ve always found doing this will put me within a few clicks of perfect, I think it’s just difficult to eyeball the exact perfect position to set the dot to on the first try.

You can’t sight the dot by placing it over the front sight post. this will induce parallax and the dot will be off. You need to sight the dot on its own. Co witness just means you can acquire the irons through the optic. I’ve lined up the dot to the irons just to get on paper, but it really does require fine tuning especially if you want to hit consistently behind 100-200 yards

Interesting to see co-witnessing in action.
I’m curious, however, as to the utility of it.
Certainly quicker target acquisition than using irons only but beyond that, what do you more tactically-trained folks see as being additional benefits?

Does it work? Seriously?
I've slaved Co-witness irons to the Dot and vice/versa for years and verify at range (36/50 or 100 yds.).My preference is MagPul "Pro" BUIS.
Works perfectly.

Nice. That’s what I’ve always done.

@4:30 – "Up would be to the right, we wanna go down" <turns knob to the right>
I've done that so damned many times.

Exactly what I do…

I been shooting with my holoson gold dot sight co-witness for the last year and I really like my accuracy

can i have the old aim point lol

Why the hell do guys still use fixed rear iron sights with red dots?! Outdated set-up, you’re just cluttering your sight picture. The Sig Romeo 4 is a great red dot.

Practical and thoughtful. Great video 👍

That's exactly what I did , set the dot right on top of the front post , I'll be testing tomorrow. Thanks Dorr

Romeo 4 fucks. One of quite a few optics finally bringing genuine competition to aimpoint and eotech.

I've done similar on a couple 300BO pistols – romro 4S and flip up sights – Ttoy Batglesights on one Magpul BBUS Pro on the other. This works OK as these are for me at least -100 to 150 yard weapons. Down 'n dirty but it works.

How less accurate are the non-free floating barrel uppers compared to free float?

Hated cowitnessing back in the early 2000s. The idea defeats the purpose of a red dot.

What's the 2nd zero point of zeroing at 36 yards?

Drink for every time he says "Tippy."

@Tactical Hyve what's your opinion on the Romeo 4 and Romeo 5 red dots? Thanks

Unless it's flip up iron sights, could work.
