can someone explain "co-witness" . Got a Colt ar15 and want to put a red dot on it. Everybody seems to talk about co witness?? help!

Co-witnessing is the relative vertical linear alignment of your iron sights with your electronic sight. "Absolute cowitness" means that your electronic sight vertical plane will be the same as your iron sight vertical plane. 1/3 upper- or lower-cowitness means that the electronic sight will be offset above or below the vertical sight plane of your iron sights; meaning that you'll see the irons through your electronic optic above or below the reticle. I personally prefer absolute, but many other opinions differ. Hope this helps.

co witness means both iron sights and red dot sight are center of the red dot sight.......therefore...its co witnessed

This is easy. Co witness is when you can use your flip up sights and your red dot at the same time. Also you can use your flip up sights when your battery runs out on the reddot without having to take it off your rifle. There might be a little adjusting of sights and reddot to get them all lined up.

Co witness with irons and a red is when the red dot and irons line up. That means if you look through your irons with the red dot on, you'd see the red dot on top of your front post. So whether you aim using the red dot or the irons, your going to hit the same spot. A 1/3 co-witness means the red dot is not on the same line as the irons but is a bit higher on a parallel line. However you are still able to use the irons through the lenses of the red dot. You'd usually see 1/3 cowitness with fixed irons so that you could use the red dot without the irons obstructing your view. absolute cowitness is usually with flip up sights as you can flip down the iron sight when using only the red dot.

yeah you can adjust it to co witness with any sight. I have the magpul flip ups and they work great together

MINE IS ROCK SOLID, i flipped my mounting bolts over to the left side, added a drop per bolt of red locktight and after getting it finger tight i ever so slightly tightened mine down a half turn or so past finger tight with a socket.. mines never budged. Even at finger tight mine was on pretty solid with no play or wiggle, is your rail aftermarket ? is it a el-cheapo or a quality rail ? is a factory rail on a AR ? im guessing the problem is not the optic.. however you never know. do other mounts fit you rail solid without issue ? contact Lucid.. they are flat out awesome to work with !

I had to low mount on my Strikfire for my Mini 14. I switched the sight to my AR and added this cantilever mount. This mount is offered in absolute co-witness and 1/3 co-witness. I went with the 1/3 and loved it. Not sure if this answered your question or not but yes, you can remove the low mount that came with the sight when you bought it and add this mount to change the co-witness. http://www.vortexoptics.com/product/vortex-cantilever-30mm-ring-1-inch-offset-absolute-co-witness

True co-witness, if your optic has a riser you may want one for this is well- after owning this one it's great but not with a BUIS installed, wish I woulda spent the extra $50 on the larue

No, because of the magnification the front site disappears. It will not be a problem, if you use a low power scope (1-4) you may be able to co-witness

The center of my optic is 1.57" above the top rail. I'm using this on an SPR type rifle that doesn't have iron sights so I'm not sure about co-witness but you can measure your sights and compare to my measurement.

NcStar red dot sight is easily mountable on a picatinny rail (I have mounted my own). The quick release also makes very easy to remove & re-mount.

the dot will move in the sight as you move your head around while looking through. I've been practicing bringing the gun up to the same spot on my cheek everytime. seems to work well that way.

No. Magnified optics will not co-witness. Go with a red dot or quick release scope mount if you want to use iron back up sights.

Yeah I see no reason why you couldn't. The green dot just isn't bright enough for my liking. I wouldn't recommend buying this reflex sight. It isn't worth it. I gave mine to my brother for his Ar15. Shop around and Good luck.

The Strikefire comes with all the hardware for your AR. If you have iron sights it will easily co-witness.

I personally have the red and green dot and love being able to switch between the two. There are times that I need to make a contrast between my sight picture and the dot itself. I have qualified with this sight on my ar-15 as my patrol (duty) rifle and it performed perfectly. I hope I answered your question, and if you decide to buy this product I hope you have as much success as I have!

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

Hi Marvin - First off I'm a noob to the shooting sports. The best answer I can give is to visit the Crimson Trace official website. I found it very helpful. Good Luck!!

It looks like there is a dovetail in front of the rear sight. You could mount a red dot. However it would move with the the slide when you cock the gun..not sure how accurate it would be..its more of a 'fun gun' for short range tin can plinking..

Not being a gun enthusiast, I don't know what he means by CO-WITNESS. I did not mount a riser on mine.
