Lower 1/3 cowitness zeroing

If its a lower 1/3 co-witness set up, get a comfortable cheek weld and fire. John working hard on zeroing a Trijicon scope In a lower 1/3 setup, the red dot will appear to be higher than the iron sights if you use a heads-up cheek weld. That's normal, and should still be zeroed perfectly fine The term 1/3 CO-witness is a misnomer...the RDS and the irons will (I say again) NOT be lined up with a 1/3 cowitness: the irons will be in the lower 1/3 of the tube, the dot should be centered in the tube.

Lower 1/3: The base of the optic is raised so the red dot is above the FSP. The question I have is, how do you prefer the EOTech to co-witness? The 516 is like most, with a 65 MOA ring and a 1MOA dot. I was figuring lower 1/3 will allow for more field of view which was why a went with the 516 (has a built in 7mm riser) The mount that comes with the PRO (QRP2) provides an absolute cowitness, not a lower 1/3 cowitness. You'll need some type of additional spacer to raise the red dot. I'm no expert on what exactly you need, because I'm happy with the absolute cowitness of my PRO (but I'm sure someone here has the answer)

There are two main types of co-witness that are normally referenced: 100% (or Absolute), and Lower 1/3rd. With that said, there are a lot of nuances at play.

  2. The lower 1/3 cowitness makes it simple: dot or dot+irons. There are lots of reasons to use both options- I prefer simple, no nonsense sight pictures. Using both eyes effectively may be enough to not need that 2/3 aperture view free of the clutter of a rear sight

Buy Trijicon RMR Lower 1/3 Co-Witness Quick Release Mount featuring For Trijicon RMR Reflex Sights, Lower 1/3 Co-Witness Adapter, Picatinny Rail Mount, Made of 7075-T6 Aluminum, Return to Zero. Review Trijicon nul I do know the 512 gives absolute co-witness. The 516 raises over the 512 by 7mm which is .275 of an inch. I'm not sure if that equates to actual lower 1/3 co-witness, but I certainly want to get the sights down low in the window of an optic, but still usable if the optic were to fail. I like the idea of the 516 over the 512 Converts low-profile EOTechs to lower 1/3 cowitness, and provides a better cheekweld too. The LT110 is another mount designed by request. The LT110 raises the EOTech by .275. This extra height sticks the irons low in the EOTech's window...you can still see the irons if push-comes-to-shove. The response has been outstanding

Only reason I might consider absolute cowitness is if you wanted to try and reduce the effect of astigmatism by viewing the dot through the rear sight on precision shots. Having said that, seems just as easy to lower your head and accomplish the same thing with the lower 1/3 cowitness For those with front iron sights, what do you prefer when using a red dot, lower 1/3 co-witness or absolute co-witness?
