EOTech Expectations

[Boba Debt]

I have Eotech 512s on my PTR-91s. I took them to the range today and dialed them in.

I started at 25 yard and was easily able to shot sub 1" five round groups.

Then I went out to 100 yards and I couldn’t really see anything on the target so I just centered the dot on the paper and shot. I could hit the 8" target but I couldn’t get any good groups.

So I dropped back to the 50 yard line and was able to get good 10 round groups.

I really wanted to be able to use this out to 200 yards without a magnifyer

I can probably do as good as I shot today with the iron sights



So my question is are my expectations for the EOtech to high?

In other words, did it do what it was supposed to do or do I just suck

Then you're doing fine! The neat thing about dot sights and hologram sights is they do everything irons can do, and do it faster, and in poorer lighting, and without fussiness about aligning tab A in slot B.

I went out to 100 yards and I couldn’t really see anything on the target so I just centered the dot on the paper and shot.

This isn't a problem with your technique or the sight, it's a target definition problem. If you can't see anything to hold on precisely, you're doing area firing. Can't be helped--you have to see it to hit it.

I think your expectations were a little high. With no magnification the hologram is going to cover most of what your aiming at at 100 yds. EOTechs are close quarter combat sights. If you want to reach past 100 accurately, I would look at a 1-4x scope. There are some very products at great prices.

Other than that, enjoy the EOTech at 50 yds... they are a hell of a lot of fun.

^^ That said, and I agree in the main, people hit what they are aiming at even with ironmongery sights, to surprising distances. If irons can do it, dots can do it. It is about localizing your sight picture to something you can hold on.

The standard Eotech has a small dot in the middle, and to some eyes it looks smaller if you turn down the brightness.

I started fooling with dot sights when the dots were yay big, Singlepoint and Qwik Point, and found my best results came when I used the top dead center of the dot, right at 12 o'clock, as my aiming point, using it like a bead sight. This removed the question of the dot obscuring the POA.

Good info so far, I appreciate that

Sound like the 512s were doing what they were designed to do.

I would like to be able to hit out to 600 yards with these rifles and I have been looking at these scopes

Are they any good?





I found a site that sells one with a 308 BDC cam for a 168gr projectile but I have noticed that most NATO surplus is 147gr.

How much would the lighter round affect the accuracy of the BDC



If these scopes are not the best for my rifle, does anyone have any recommendations for another

I would have to echo what was said above. EOTechs have that 1MOA dot, but they are then surrounded by the 65MOA circle which is known to cover a lot of the target at intermediate and longer range.
There are lots of things to consider. The target is one, and I would suggest going to a better type of target with more contrast that you can see at that range. Also, I would recommend fiddling with your illumination as you shoot. The lower the illumination, the more fine the reticle will appear and you will likely have better accuracy. When you're trying to do more precise shooting with an electronic sight, it does help to turn down the brightness to where it's either barely visible or just slightly more than that.

I just got the Leupold Mark AR 1.5-4x20 for my AR & ACR...zeroed at 25yds but didn't get a chance to try 100yds.

With no magnification the hologram is going to cover most of what your aiming at at 100 yds.

It's a 1 MOA dot. At 100 yards it subtends a smidge more than an inch. Unless you're shooting at quarters or other loose change target obscuration shouldn't be a problem.

If you're new to red dots, one thing you might check is that you don't have it set too high. A lot of people crank EOTechs or AimPoints up to the point that the brightness is interfering with their ability to see that target.

After figuring hold over (which took a little trial and error) I didn't have trouble making consistent hits on 19" wide steel chest plates at 600 meters with an M4 and Mk 262 on more than one equation. I'm not the best shot in the world, so I'd take that as indicative of what the optic can do. (Much trickier shot with an AimPoint, at least the 4MOA dot issue CCO.)
