What is the height over bore for this red dot sight when it is set for 1/3 co-witness?

I am actually not sure, about a year ago I bought a Comp M3 w/Larue LT129 Mount which is a true 1/3 co witness. After buying the comp M4s w/QRP2 mount I am much happier, as the optic sits a little bit lower. I have BUIS and keep them folded down most of the time anyway. However, when the BUIS are flipped up and the M4s is sighted the red dot sits on top of the FSP. I have since sold my Comp M3 and the Larue Mount. Much happier with this setup and by the way, this is the current military issue from Aimpoint. I love mine...

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.

I use it with a eotech exps2 which has a raised 7mm base. So it matches up perfectly with my eotech. With a normal height front magpul metal sight, there's a 1/3 cowitness. I haven't measured the height of the center ring itself but hope this helps.

I have no idea. You might contact UTG and give them the make and model # of your front sight and the make and model # of your red dot sight and ask them if it would co-witness. Otherwise, just order the UTG 5-slot QD adapter, try it out with your red dot mounted on it, and if it doesn't co-witness with your front sight, send the UTG 5-slot adapter back for a refund.

Co witness is viewing iron sights through the red dot optic. A full co witness will align the dot in the center along with the iron sights. (Aligning all three sights if needed) a lower 1/3 will have the dot in the middle with the iron sights aligned just below the dot. Co witnessing is generally used as a means of using iron sights as a back up to a dot sight, while keeping the dot sight mounted. Either way the dot and iron sights should ALWAYS be sighted in separately. Hope this helped!

This Riser will make it a 'lower 1/3', it is probably not a 'Absolute co-witness'. I have a red dot scope mounted on this riser and I can not see my (G36)sights through my scope.

To adjust the red dot you can use a penny or a flathead screw driver. It's an awesome sight. Def lives up to it's name.

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

I can see the .223 holes from 100yds. Anything further becomes difficult for me. It will work with most red dots just get the right mounts.

It is a matter of personal preference mostly. An absolute co-witness should "Dead Center" the optics Red/Green Dot Reticle in the center of the optic, and align with with your BUIS (Back.Up.Iron.Sights) in the middle of your tube . With a lower one-thirds Co-witness, your Iron sights will appear through your Red Dot Reticles tube, in the lower one-thirds quadrant of your Red Dot Tube. Depending on the height of your picatinny Rail setup, you can Add/Remove a 1/3rds Riser mount, to adjust your red dot sight so that it aligns properly with your Irons. Which ever one you go with, try it out first and see how everything lines up together. If it isn't quite right, try the 1/3rds Riser mount. I know that TruGlo makes one.

Hard to say because it will not fit on any rail system that i have. So I'd suggest going with a different red dot.

Yes, I have the Strikefire mounted with this cantilever mount & I have it paired with the Vortex VMX-3T magnifier. Gives me 1/3 lower co-witness. Check Vortex web-site for further info, here is what it says about this mount. "Provides lower 1/3 co-witness mounting height of 40 mm. Will work with most 30 mm red dot sights."

about 3 inches, I purchased it because a friend of mine has one and it goes great with my eotech on a ar15 results are just right. all info really depends on what the person likes or dislikes. to get high quality off of something you gotta pay top price also.

The riser on this model is 1" I typically use a .8 or .75. This is set for what is called a 1/3 co-witness. If you could use a lazer chamber bore sight. it may help. What I am saying is the mount is a bit tall. This might be the issue. I will say that I have mounted probably 30 of these units and I have never had a bad unit, I have had bad mounts.

I cannot speak to the question of the red sight being the same height as the green (through I would assume it is), but I purchased this sight for my Range Officer, and use it with no problems. Even from long distances I am pleased with my accuracy.

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

This cantilever mount will provide you with a 1/3 co witness. Basically it will allow the user to sight or view through the red dot easily yet still allowing you to use your iron sights. Your iron sights will be viewed through the lower 1/3 of your red dot. It has a 30mm forward cantilever allowing the user to also mount a magnifier by requiring less space on the pictiny rail.
