Co-witness: absolute vs lower 1/3

Featured Replies

Lower 1/3 fo sho

 

Much less obstructed view through my optic. Also, it might just be me, but even when my optic goes down, I know where my front sight needs to be in the window for emergency hits at close quarters.

Lower 1/3 without a doubt.

 

It's a more comfortable and less fatiguing head position, and I like a standard FSB over a flip up style, so the higher optic allows me to have a clearer field of vision.

It ain't just you. That is a viable TTP and one that is taught regularly to those doing CQB. Some guys even paint a GITD/Hi Vis stripe on their FSB to help center everything.

 

I know I regularly train on that technique with single head shots out to 10 yards, multiple COM shots rapidly out to 15.

Agree on the lower 1/3.  If you are inquiring based on your tavor purchase one benefit of that rifle is that the sights fold down so either would work for you. 

Depends on the optic. Full size like an M3/4 lower 1/3. But if its a T1 Micro, I prefer true cowitt.

Thats a neat thought. Maybe I'll try that.

I have a a folding front sight on my 16" AR, I always keep it up now. I can see it being a pita if I needed it and it was down. With the lower 1/3 I don't even notice my sight with or without my magnifier

 

Just my .02

+1 on the micro.  I prefer full cowitness in general, but lower 1/3 doesn't bother me on sights with more tube/window. On the micro or other narrow tube dot, it never really gets out of your way anyway, sooo... 

I like the lower 1/3 on my AR. My AR has a normal front sight and I feel like the sight is in the way with the true co-witness. If I had flip-up front and rear sights then I probably wouldn't care.

Interesting. I am the exact opposite.

 

With the smaller diameter of the T1 tube, I will always use a lower 1/3 cowitness as it leaves more of the smaller "window" clear to find the dot and obtain a decent sight picture.

 

With larger "tubes" like an Aimpoint PRO or M4/M4A or even an EOTech (yuck) I can deal with a lower cowitness (anywhere from absolute to lower 1/3 - even the in-between height that the PRO OEM mount offers) as there is more "window" and any object interfering takes up a smaller percentage of what I can see through the tube.

 

I also find it more fatiguing looking through that smaller tube of a T1 at absolute cowitness height. I find the larger tube optics to be more accommodating there as well, requiring less "Turtling" and offering more forgiveness with a quick or sloppy mount while acquiring the dot from a low or indoor ready position.

 

ETA: Either way, I prefer a lower 1/3 co witness with all RDS type optics regardless of the tube size; although if pressed I will begrudgingly accept an absolute cowitness with the larger optics if I have to.

Bahahha!

Definition- Turtling as referred to optics:

using your rds in extreme cold.

I should add for clarity that with full size aimpoints my front and rear are fixed, with a micro my rear is folding.

Good point for relevance: I have fixed front (std FSB) and folding rear on all of my ARs.

 

 

With a std FSB and a T1 in a LT660 and a std FSB and a PRO. I have been using fixed rear sights.

 

Why the folding rear buis on the T1 guys?  (Just curious, not attacking)

Real estate. Less real estate in a T1 so I dont want obstructions. In addition I think its not to bad for a com shot using the t1 as a rear ghost ring if I had to. With the M3/4 I have enough real estate that the obstruction doesnt bother me at all. No right or wrong IMO, just preference. The fact of the matter is that for all the years I have been a proponent for the aimpoint, my aging eyes are disagreeing with my position so Im running a S&B short dot on my primary rifle at this time.

Ok understood.  Also I am jealous of that S&B short dot, maybe one day I'll have one.
