How is it for co-witnessing iron sights? Does it sit too high, or low on the rail like an EoTech?

It sits pretty high on the rail so co-witnessing will be a problem unless you have aftermarket sights possibly using a riser to bump them a little higher. I'm pretty sure that it won't co-witness with any stock sights on a firearm.

To the best of my knowledge it co-witnesses just like most of the eotechs (aside from the ones with a riser)

It sits high but I still get a bottom 1/3 co-witness with the Daniel Defense fixed rear sight and standard A2 sights I use on my set-up.

I have perfect, centered in the window, co-witness with my Magpul MBUS, sitting on a standard rail.

For the money go with an EoTech. I returned my MEPROLIGHT because the mounting didn't feel solid, even after adjustment. Maybe I got a bad one who knows. I already spent the money to swapped it out for a Aimpoint T1 micro and haven't looked back since. But to answer your question, I felt it sat to high on the rail.

it sets ptetty low. it actually sets a little lower than an L-3 EOTech on one of my other guns. when I 1st mounted this unit I'm pretty sure I set the sight by putting the dot on top of the front sight and I was pretty close to right. I have since changed out the gas block on that rifle, so I can't go check it. but yes your front sight is visable thru the lense. rear sight no. if you was a set of functional iron sights to use with this as. a back uo, you will have to go with a set of off set aux. irons. but the Mepolight has a quick disconnect mount, comes off with two flicks of the thumb.

You're asking if this is true or lower 1/3 co-witnessed. The m21 is a lower 1/3 setup

Very good question. The rifle range where I live in Texas closed as the owner retired and I have been unable to shoot my Meprolight M21 which is on my Rock River AR15. Here is what I have observed. The front iron sight is very visible and centered (neither high or low) on the M21 when one looks throughout the M21. One can align the Orange dot on the front iron sight easily. It does not sit too high or low on the rail mount. I can't wait to take the firearm to a range and see if the iron sight is advantageous when used with the M21. I don't mind sending you a pic of my M21 mounted on my rifle if you think that would help you. My Email is: TTUAlumni@msn.com. Hope this helps a little. Stan Very good question.

I have mine mounted on a m4 with mbus sight. I can co witness with no issues. Great sight. My only issue so far is that sometimes the auto off does not work.

No problem with iron sights. I modified to allow easier cleaning. (Then I replaced the whole thing with the Tapco which costs $10 more and couldn't be happier).

it should be fine. it's not completely tall enough, but with a scope the worst you might get is a slight blurring of the sight at the bottom of it. most likely you will not see it. I eventually removed the front sight block and but a gas block with a short rail section on, I wanted offset sights so I could tilt the rifle and use iron sights if the shot was to close.

I don't know of any sight that will co-witness through this mount. It just sits too high on the weapon. Instead, I put a DMP5 red dot sight on my MP5 22. It self mounts to the gun, is reostaticly controlled and co-witnesses perfectly. Price is reasonable also. Hope this helps.

The SPARC comes with mounts that give you an absolute co-witness (sights and dot lined up all the time) and lower 1/3 co-witness (the sight is placed a little higher so if you pick your head up a bit, the iron sights won't be in the way but you are still able to co-witness and use the irons if you drop your head down a bit). The Strikefire has better battery life and has a larger objective lens. It has an absolute co-witness out of the box but you can buy a mount for a lower 1/3 co-witness for about $30.

Yes, this mount will give you full co-witness. Meaning that the top of your front sight will sit in the middle of the red dot.

I mounted standard flip up iron sights in my AR. You can see the sights great right through the multi dot. Don't know why the reticle on top or a later on the side wouldn't work also. Very versital!

The sight sits kinda high above your rail, so yes, you should be fine. Mine has a flat front gas book and so front sights would not be an issue for me. It may be visible if you have a raised front gas block, but should not obstruct your crosshairs.

It works for me. I have a gas block mount front sight as well in a co-witness setup.

It is set up at the standard sight height for an AR. What determines the co-witness capability is the mount height you use for your optic. The mount for your optic will determine whether it will be absolute co-witness, lower third co-witness, or completely prevent you from using the iron sights. Do research on the mounts and optics you want to use. But, this sight won't be the reason why it won't co-witness. It is a standard height iron sight.

Whether or not your rings are too high depends on how you are built and your intended use, so I cannot answer that. Once properly installed, iron sights use should be possible with or without scope.

Depending on the mount you choose, and what iron sights you are using, then yes, it will co-witness...

You can mount a red dot sight on there. That's what I have done. I love the fact that I can still use the iron sights if needed.

Well the rail is low, but you cannot see the iron sights like it said in the ad. I never put it on the gun, so I never got to the ring phase. I suspect any would work, it just a matter of your cheek weld and what is most comfortable.

It would sit pretty high if you could find a way to mount it to the carry handle and while the optic is parallax free doping it would take a little more effort i would think being that far from bore level. The optic comes with a picatinny rail mount as standard.

The sight will 1/3 co-witness with the irons depending on what sights you are using. I am currently using gen 2 magpul Mbps sights. The emitter in the sight is located at 5 o'clock and partially blocks the front sight so that you can see the FS post and the left blade. Personally I would buy the sight w/o the hi rise block and invest in a better mount. Daniel Defense makes a absolute co-witness riser that runs around $60 on amazon. Good luck
