First off, \u00a0I am sorry for not even sitting down and doing a video explaining what co-witnessing is. \u00a0There are two definitions on how to Co-witness an optic. So let’s start off by making sure everyone understands them. \u00a0This becomes incredibly more confusing since different optic manufacturers will use the term that most benefits them when referring to Co-witness.<\/p>\n
1) Definition #1: To Co-Witness an optic on a gun means that even if the electronic systems are down, your flip up iron sights can be used as a mechanical backup to an electronic failure. \u00a0These sights will normally show up in the lower1\/3 of your electronic dot system and remain visible in the event of a down optic. \u00a0This definition is a definition that nearly all optic manufacturers are able to come up with some way of supporting.<\/p>\n
2) Definition #2 (I like to refer to as sometimes the Aimpoint definition and the one I prefer): To Co-witness an optic on a gun means that the rear ring\/wedge\/etc. lines up it’s point of impact with the center of the red dot which lines up to the impact point on your front sight. \u00a0This means you could draw a straight line from the rear sight, hit the dot and then hit the front sight.<\/p>\n
Let me illustrate it with a few photos:<\/p>\n
Eotech’s\/most of the industry:<\/p>\n
<\/p>\n
Notice how on the photo on the left, two different Eotech Models create two drastically different Co-witness lines. \u00a0The Eotech 512 maintains a true co-witness to line up the iron sights, but the 516 sits up to high and allows you to only see the iron sights in the lower 1\/3 of the window, the center of the ring not lined up with the iron sights. \u00a0However, by basic definition, they are both co-witnessed because you can still see the iron sights in some form through the window in the event the electronic sights would not operate.<\/p>\n

Now look at the photo on the left. \u00a0All Aimpoint Optics with proper spacer kits line up correctly with a true Co-witness. \u00a0The rear iron sight is looking directly through the center of the 3x Magnifier which is looking at the red dot that is in the center of the Aimpoint which is looking at the impact point on the front iron sight. \u00a0Everything is completely co-witnessed with each other.<\/p>\n

I am going to skip the virtues of the Micro T-1 since I have covered that in another episode. \u00a0What I want to tell you about and make sure you understand are the two primary mounting options. \u00a0Each has a different price point and I want you to understand the pros and cons of each.<\/p>\n
This option is offered from Aimpoint and I sell them myself. \u00a0The Spacer kit has an MSRP of $71.00. \u00a0You can purchase it from me here<\/a> at a cheaper price. \u00a0I \u00a0<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n \u00a0<\/p>\n![](\"http:\/\/www.civiliantacticalweapons.com\/wpctw\/wp-content\/uploads\/2010\/05\/aimpoint12358.jpg\")
tend to keep them in stock for people who want to buy a Micro T-1 from me. \u00a0They are assembled by unscrewing the four screws on the bottom of the Micro T-1 to disconnect the base and put this spacer in between the Micro T-1 and the old base and using the four longer screws included with the kit. \u00a0This allows the Micro T-1 to sit up for a true Co-Witness with an AR15\/M4 sights. \u00a0This is a very basic spacer kit and does the job as needed. \u00a0It is very cost effective compared to the other option I will be talking about, but is a rather fixed option since it requires a tool to take it on and off. \u00a0Personally, I never remove optics from my guns since regardless of what a manufacturer says about returning to zero after it has been remounted, I still don’t like doing this. \u00a0The only thing I want to mount and unmount is a magnifier for my gun.<\/p>\nLaRue LT660 Mount for Micro Series<\/h2>\n

to always keep one around in stock at least. \u00a0This is a popular after market option offered by LaRue who makes excellent mounts. \u00a0That being said, they are very expensive. \u00a0If you don’t care about price, this is an excellent mount. \u00a0It allows you to mount and unmount the option with ease using a quick release throw type lever. \u00a0The manufacturer claims a return to zero within a 1 MOA if I am not mistaken. \u00a0If you are looking at an optic to move from multiple guns and you don’t care as much about having to re-sight an optic in for a different guns, this is the option for you. They are made of very high quality and I offer them to my customers who may not be as cost conscience.<\/p>\n
