What is with people hacksawing their A2 sights?

I thought co-witness was the whole reason those optics are that height. I guess I could understand if you were using a traditional scope, but I was under the impression you were supposed to see the front sight in a red dot.

I don't know why you would want it to co-witness. What would be the reason for this? I've got a Eotech on one of my ARs and it works fine without a co-witness front sight, looks to me like the front sight would just be in the way.

So that if/when the red dot quits working, all you do is flip up the rear sight and keep going.

I often us a matech sight and a holosun red dot together that uses 1/3 lower co witness. This has a number of advantages.

 

1. Matech sight can do elevation adjustments out to 600 yards with presets.

2. I still have my front sight available for range estimation

3. When shooting for distance, I set the iron sights for the distance and then move the red dot to sit just atop the front sight post

4. I can then flip down the rear sight and raise my sight line ever so slightly so that the fsp is no longer in line with the target providing ample view

 

 

I have used this combo to great success at a know distance Appleseed event scoring a 44 out of 50 and earning the KD rocker for the rifleman badge.

 

Unless you have some other object available for range estimations, such as mildots or other ranging reticle, I find the front sight post to be a fairly critical tool on a rifle for more than just aiming.

I won't use an Eotech with an A2 sight. I will with an Aimpoint using lower 1/3 cowitness. Lower 1/3 sucks with an Eotech (IMO), and the sight is in the way with full cowitness, again IMO. My Eotech guns have flip-up front sights.
