Aperture Rings Kit
As I progressed learning why instead of seeing a red DOT I see all kinds of figures and shapes but the dot, and especially after conversation with one of the support technicians at the Trijicon, who politely recommended to find and see a “shooting” eye doctor, search for options began. I read through great articles by Dr. Norman Wong, various blogs and posts by fellow shooters, found shooting eye doctor, - in short, I devoted quite a bit of time to understand what can be done to help me dealing with my aging eyesight and astigmatism. It was also helpful that one of my other “shooting” hobbies is photography. Understanding how Aperture works with photo lenses, some of the suggestions I found in Dr. Wong’s articles - Concentric Ring Enhancer, studying various EyePal / Optical Attachments to shooting glasses led me to designing and machining Rubber Band and Aperture Rings.
Without a question Rings enhanced my vision (shooting is a different story, but at least I can see where I shoot now!). However it took me quite a bit of time to adopt. In order to maximize benefit of vision enhancing rings, aperture must be as small as possible for distance, size of the target, light conditions, and the course of fire (i.e. Slow Fire versus Sustained Fire in Precision Pistol that I shoot). I estimate that it took me over 50 hours at the range to move from 0.700” aperture to 0.200” shooting at 50 yard slow fire course, and to 0.350” at 25 yards without losing the dot between shots.
I finalized on the Set of Rings you can see here. Rubber Band Rings have 30mm and 0.700” IDs (30mm is included in the Set, 0.700” can be ordered separately. I also include one free Rubber Band Ring with purchase of my shades for Aimpoints Micro H1 or 9000SC). Aperture Rings have 0.700”, 0.500”, 0.350”, 0.200” and 0.125” IDs. Aperture Rings have the same thread as 30mm Ultradot’s Polarizing filter, Rubber Band Rings have the same thread as 30mm Ultradot’s Extension Tube. Thus entire set can be used with 30mm Ultradots, but might require additional trim ring as Ultradot reversed thread sizes from front to back in different models. Such rings (and extension tubes) can be ordered through Ultradot’s website.
For sale is a set of 5 (FIVE) Aperture Rings plus 1 (ONE) 30mm Rubber Band Ring. Other parts seeing on pictures, - shades, Ultradot accessories, Trim Rings and of course my gun (as pictured) are not included.
First Batch of Aperture Rings Set is sold out. Second batch is in Anodizing and will be ready mid to late November. Backorders are accepted.

I recently ordered a set, the shipping was fast, and overall I'm very happy with the product. I shot a 900 match and my slow fire scores were 3-5 points higher than usual, so I can definitely see that it worked for me! The sustained fire scores were not as good, but this is of course just a first impression, and I will continue testing in different conditions - so this is work in progress. I published a detailed review in my blog and I will provide my updates there as I progress.

I've been experimenting with the Aperture Ring Kit for the last several months. I initially was only interested in the rear ring (rubber band ring) and was skeptical of the aperture rings. I was skeptical because of my being set in my ways and not as flexible as I really should be. I think the Aimpoint 9000 is the best bullseye optic made. The red dot is nice and round and bright even when small MOA setting (which I like) and the lens clarity is near perfect. Only thing I do not like about Aimpoint optics is the very fine windage and elevation adjustments. My first experience with the rubber band ring was positive. I prefer shooting using the red dot as the front sight and the optic tube as the rear sight. So I strive to keep the red dot centered in the optic tube as much as possible. What I immediately noticed about the rubber band ring is that I had less eye bounce as I call it; eye darting from red dot to the optic tube. The optic tube becomes more clear peripherally for me. When I shoot matches I normally show up on minimal amount of sleep and tired right out of the gate. I found that shooting with the rubber band ring I had less felt eye fatigue. At this point I can't imagine shooting without it. The aperture rings took some open mindedness on my part. I've always liked using 30mm optics and always thought that the extra field of view was an advantage. I initially experimented with the aperture on the rear of the optic tube only because that was our first test parameter. I was here nor there about it and most likely wouldn't have used it alone. But after getting a prototype front aperture it was like the optic came alive. In other words, I think the combination of the front and rear aperture is the way to go. It seemed to visually help keep the red dot more centered. I found I liked it mostly for slow fire and would change to a larger diameter front aperture for the short line to open up the field of view. I've been battling with my eye drifting from/off the red dot on my 5th shot on the short line and throwing a shot in both timed and rapid fire. The smaller field of view has helped to keep my focus on the red dot and not look at the target. I have tried both bare unfinished aluminum and the red anodized apertures. The bare aluminum is a little bright and the red anodized surface seems to have just the right contrast to keep the red dot the primary objective visually. I've shot both with and without overhead cover and find that the red color works well. The front aperture will appear black when looking through the optic, so the anodizing is purely ascetic. The front aperture size should appear slightly smaller than the rear aperture when looking through the optic. This aids in keeping the red dot easy to find as well as its really the right way to use it. It gives a feeling of a more centered red dot which could for some people lead to better accuracy/grouping. I think it could also be a great training aid as well. When you're working on grip and wrist consistency with a smaller aperture it will show you inconsistencies better than a large 30mm optic tube. I found that I had no problems losing the red dot during recoil with the apertures. I found that I preferred a middle ground aperture size from the kit. I don't look at the apertures as a gadget or gimmick. They truthfully have merit that I believe can help a shooter be more consistent or grow as a shooter. At a minimum, I would highly recommend the rubber band ring. I will point out that if you do not have a grasp at the fundamentals that using a smaller aperture could be a detriment due to limiting the field of view. The Aimpoint Micro has a slanted/angled projection inside the optic for the red dot projection. It has always bothered me. I have used the aperture rings on it and like that I can make that disappear. I have been shooting bullseye since 1989 and at one point was shooting high master 2650 scores. So I have mastered the fundamentals fairly well. I'm saying this because I believe shooters at or near this level probably will not gain as much as a lower classification shooter. But I do believe the rubber band ring to be a huge assist on keeping the optic tube concentric on the red dot. So I'm interested to see how they continue to work for me in the future.
