It is absolutely a personal preference thing.
An important factor is the style of BUIS you are cowitnessing to. If you are using fixed irons then most people prefer a lower 1/3 because it means you are looking over the top of the irons so there's less to get in your way. If you are using flip-up sights that are normally in the down position or if you are just not going to have iron sights then it doesn't matter at all. |

I'm changing my setup a bit... I decided to sell my Primary Arms 1-6x scope to get one of their RDS. For how I use my AR, I think an RDS would serve me better. In looking at the options for mounts, that got me thinking... absolute cowitness or 1/3 cowitness. So my question to you guys is - which one do you prefer and why? Are there advantages/disadvantages to either or is it just personal preference? preference, I like the eotech 512 why 1. mount included on optic so no 100-150 dollar miunt absolute co witness allows standard cheekweld once eotech is zeroed just move the orons until the dot rest on top of the front sight & bingo all is zeroed. |

Yup, this is what I did. |

There is no correct answer. It is a matter of personal preference. If the front sight is fixed A2 style, a lower 1/3 cowitness avoids blocking the lower part of your field of view as much. With a folded front sight, I prefer absolute cowitness, so my cheekweld remains the same as when shooting irons.

I prefer lower 1/3 co-witness. Funny this question should come up. The other night I was browsing YouTube videos and came across this kid. I think he sums it up pretty well.

Thanks for all the help guys. I currently have fold down iron sights, so I guess it comes down to preference... I'll probably end up purchasing the RDS first and see how I like it. If need be, I could always get a riser. Now I just have to worry about selling my PA Scope...

You will be scrunching down and it may be blocked by even a folded front sight. Depending on what red dot you get, there are cheap risers on the Primary Arms web site for both absolute and lower 1/3 cowitness. You will need one or the other if your red dot does not have one built in. |
