Sharpen Your Red Dot

I have written before about how the aiming dots on some Aimpoints don’t always look very crisp to my eyes. Yet, I continue to use them because they are clearly the best red dot site on the market. The Aimpoint Micros (T-1 and H-1) in particular appear more like a starburst than a dot to me. This makes accurate shot placement challenging especially as the distance from the target increases. I continue to use them in spite of all that because of their amazing combination of compact size, light weight, long battery life, and extreme durability. Well, that and I have a work-around.

Aimpoint Micro

I am certain that it is not unique or original to me but I have found a simple work-around for the issue that works very well for me. I simply look at the aiming dot through the small aperture of the rear sight when precision is needed. Looking through the small aperture makes the dot in an Aimpoint appear perfectly round and crisp and it also seems to bring the target into the same plane allowing both the dot and the target to be relatively crisp. There is obviously some principle of light or vision at play here that is beyond my ability to explain. Go try it now and you will see what I mean. I’ll wait…

This isn’t a perfect fix and it isn’t for every situation. It might require some adjustments to your carbine and may not be for everyone.

When to Look Through the Rear Aperture

This is obviously not a technique that is applicable to all situations. I find that there is really no need to do it until distances extend beyond 100 yards. You certainly would not want to spend time finding your sight picture through the small aperture if you are engaging a bank of targets that are just 25 yards away. There is really no need to because even if the dot is slightly misshapen to your eye, it still probably offers an acceptable level of refinement for this task.

To be clear, I am not advocating that you always look through the rear sight when using an Aimpoint. The approach that works for me is simple: I look through the rear sight only when time allows and/or the accuracy requirement of the shot requires it.

How to Configure Your Carbine

I am not sure there is a hard and fast way that your carbine must be configured for this to work though I have found that there are probably some best practices. For instance, I don’t think it is a good idea to have to deploy a folding rear sight in order to look through the small aperture. This is doubly true for sights that do not deploy with the small aperture in place. I keep my rear sight in the up position to avoid this.

I find that I prefer a lower 1/3 co-witness setup in general but it also happens to be well suited to this technique. It allows me to easily look over my deployed rear sight while maintaining a normal cheek weld when the need for speed is more pressing than the need for a sharp, crisp aiming point. When I need that crisp aiming point, I simply press my eye down to the iron sight.

I should probably also note that I still keep both eyes open when using this technique. I find that my brain can switch to the clearer view through the rear aperture fairly intuitively. This principle should be easy for those who are already used to using magnified optics with both eyes open.

Wrap Up

I want to reiterate again that I am not advocating always looking through the rear sight when using an Aimpoint and I am not saying that it is necessary to look through the sights to use an Aimpoint (this misinformation seems to come up time to time). This is simply a technique that works for me when the specific set of circumstances that allow it arise. Try it sometime.

    Wouldn’t looking at the dot through the rear sight with a lower 1/3 co witness create a miss alignment?

      If you are inside of the parallax distance it likely would but beyond 25 yards it is fine.

    Just gave this a try with my T-1 and it works! At least indoors in front of my computer it does. I never had the problem of the starburst dot until I got laser eye surgery. Thanks for the pro-tip!

    If the Red Dot and the Iron sights are zeroed the same this will still work even if you are running a lower 1/3 co-witness mount. You will see the dot “suck down” to the top of your front sight post when you look through the small aperture – and the dot will be very crisp..

    After my Laser eye surgery succumbed to my need for reading glasses I discovered this same trick. As an Aimpoint dealer I have heard the same complaint about the oblong or fuzzy dot and I don’t see it with my corrective lense or in corrected vision. Thanks for a great tip, I thought it was just me!

    I just tried it with my Vortex StrikeFire. I was experiencing the same issues with it. It works great. The dot is crystal clear and very precise.
    I am running Troy flip up sights in absolute co witness but can raise my sight and change apertures in one fluid motion. I think the benefit at long range is worth the second it will take to open the sight. Great tip.
