[Guest Post] Aimpoint Micro Anomaly

    [ This guest post was written by M.J. Mollenhour ]

    Anomaly: something that is not supposed to be, according to theory or design. I have a Space Invader running around in my Aimpoint Micro T-1. I should warn you about it.

    Aimpoint Micro T-1

    I own the Aimpoint Micro T-1 and I am not giving it up, or sending it back. The T-1 is right for many reasons. For example, the body of the optic is so small that it need not create a “visual tube” that would otherwise occlude the field of view outside of the tube. The sight just won Petersen’s Hunting Magazine’s “Editor’s Award,” and for good reasons. I am sure the company is proud of the device, and I am grateful for Aimpoint’s solid contributions. Keep them coming, though I don’t know how much more battery life you can achieve beyond 50,000 hours, and surely you cannot make the optic’s body disappear altogether!

    However, every device has characteristics that create “quirks” and this post is about one I discovered with the Micro T-1. It is worth knowing the limitations of the device.

    I shoot often at a location that is a narrow valley, facing due west, with a ridge as the impact area behind the targets. This means that, later in the afternoon, targets will be in the shade but the sun will face the shooter, at a shallow angle. Here is what it looks like.

    Targets at end of valley facing due west late afternoon

    At approximately a 20 degree angle—sun above muzzle by 20 degrees—the shooter using an Aimpoint Micro will see a reflection of the red dot’s diode circuitry, surrounding the dot. If this were ghostly, or tiny, I would not be writing the post. However, at 200 or even 100 yards, the image is sizable enough, and opaque enough to block the shooter from seeing the target altogether. Here is what the shooter sees at 200 yards, with the dot-diode Space Invader off to the side so you can see its reflection, the sun, and the targets.

    Two IDPA targets lower left, sun upper left, “space invader” prominent

    You see the three, parallel bar, lobster-like image I am naming “Space Invader.” The red dot is in the hole in the bar in the middle, where the lobster’s eyes would be. Two IDPA targets, at 200 yards, are in the shade in the lower left corner, and show you the relative size of the targets compared to the anomalous space invader, red-dot circuitry image. The bright spot showing through the trees, upper left, is the sun. Now, picture what all of this would look like with the red dot moved to the target of your immediate attention. The Space Invader obliterates your view of the target.

    Think Taliban attacking an outpost, late in the day, topping a hill, and now on the downhill (shaded) side, coming from out of the west. MJM does not think he is being picky to call this a problem with the optic’s design.

    The shooter will not experience this on a cloudy day. You may own a Micro and never see what I am writing about because of where you shoot. (That is another reason why we need to fire our weapons in a variety of weather, locales, conditions, and affected by other variables.) Also, with the sun more than 20 degrees above line of sight, the reflection begins to fade, and it fades altogether if the sun is 30 degrees higher than line of sight.

    I do not experience this with a conventional telescope sight, even a relatively cheap one. Of course, you cannot shoot directly into the sun, and shooting at a shallow angle into the sun will affect your vision. However, for example, with the Bushnell Banner 1.5x–4.5x scope (about $90) I used to compare, the glare did not occlude the target.

    Neither did I experience this with the Aimpoint Comp M2, used at the same time for comparison. At a very shallow angle (less than 20 degrees), the shooter using the M2 will begin to see the “ghost” of the circuitry, but it is faint, and considerably smaller than in the Micro.

    Before you tell me to “send it back,” thinking my Micro is defective, I took the opportunity to ask an Aimpoint representative about this phenomenon at the SHOT Show in January, 2011. He told me that the length of the barrel in the Micro sights is just so short that the diode’s reflection cannot be completely eliminated.

    I understand that. Everything is a trade-off. Like I said, I’m not sending mine back. But, if I knew then what I know now, I might have bought the Comp M4 or M3.

    A few more observations about using the optic

    Aiming with a red-dot sight is natural and fast. Forget the device exists: target and dot.

    Aimpoint’s manual includes only two trouble-shooting pointers. One of these pertains to the battery. The manual advises you to clean the battery and terminals if the dot does not light. I found this to be good advice. One fell0w shooter experienced the dot turning off after one shot. Turning the on/off switch did re-light the dot. However, this disturbing occurrence apparently is caused not by interference in the switch, but, rather, in the battery connection. I supposed it is too much to ask for a battery to sit in the device for all of those hours-days-months-years that it will last in an Aimpoint but it’s good for the shooter to know. I made a note to remove the battery (easily done in seconds) and wipe it clean from time to time. In my novel about to come out, Amazon Avenger, Jack McDonald, the hero, finds himself equipped with the Aimpoint Micro and immediately takes the battery out and wipes clean the battery and connections. Aimpoint recommends it, and my experience backs them up.

    If you plan to buy one, and if your AR has a fixed front sight, be sure NOT to buy the LaRue mount that provides absolute co-witness. You want the one that provides co-witness in the lower third of the optic. They call it the “tall” mount.” If you order their combination with the mount that gives “absolute co-witness,” that mount will definitely line up your iron front sight—right in the center of the optic. They make the lower-third co-witness version for we shooters whose front sight is the fixed post. My compliments to LaRue for excellent customer service in accepting my return, and correcting my error.

    I do wish Aimpoint still made one with 2x.
