W/ an aimpoint m2 equipped 16", adj. stock Pre, nose to charging handle, proper cheek weld, I see a red reflection, from the 9 to the 6 pos., clearly, when front lens cap closed,scope on or off. W/ the cover open I get some ghosting of the same red shape. More so when muzzle covers a darker area. W/ cover closed if I move my cheek weld over toward the 3 pos. the reflection becomes red miror-"ish". W/ cover opened, it again becomes slightly more visible  Is this common/normal or is there a problem? Never experienced this w/ my "M" model. |

I believe I have the same as you on my two new M2's. It's an intermittent occurrence that depends on the lighting and angle of my cheekweld. Also, I don't see it if I'm outside. It looks like it's the exact opposite side from where the dot is projected, a reflection of that. Having the dot intensity set too high also contributes to this. I haven't had a chance to fire my AR's with the Aimpoint's, but it doesn't happen enough for me to be concerned about it. Chris |

To those concerned and those that offered assistance, this was Aimpoint's response: This reflection is infact a defect. The reflection is coming off of the diode housing. It usually causes a distinctive line in certain light conditions.Probably the best way to solve this problem, would be to have you send the sight to me, along with description of problem, contact information, and any warranty information that you may have, ie.proof of purchase. I will do a replacement warranty for you. Unfortunately we are out of stock of the M2's. We are expecting a shipment in about two weeks. Kind regards, Paul Needham Technical Support Aimpoint Inc. 3989 Hwy 62 W. Berryville, AR. 72616 1-877-246-7646 There might be others out there experiencing this problem thinking its normal. Give a call to put your mind at ease. FYI, -Sul2 |

The reflection that Paul Needham is referring to is one caused by a very specific manufacturing issue. When each Aimpoint is being readied for assembly, the inside of the housing in coated a non-reflective black. A separate step is to coat the top of the diode housing itself. Occasionally this is missed or not fully coated and this is where the specific "defect" stems from. It is rare however. Any Aimpoint will show a red hazy glare when backlit, especially by a flourescent light source. That is why many notice this indoors but not outdoors. (It is also noticeable if you are outside early morning or late afternoon with the sun behind you). Before you send a scope to Aimpoint, only to have it returned, look inside the tube with a bright light source directly behind you. You should be able to see the light reflected back to you off the lens coating and, if you tilt it just right, the same reflection in red coming back from the front lens. (This is how the red dot itself appears, when the diode projects it against the front inner lens and it comes back to you). If the diode housing is not coated you will also be able to clearly see the flat top of the diode and it will be shiny. This is the defect Paul spoke of. It is rare. Paul [url]mstn.biz[/url] |

Quoted: Any Aimpoint will show a red hazy glare when backlit, especially by a flourescent light source. That is why many notice this indoors but not outdoors.

When this occurs, especially under the flourescents like you mentioned, I do see a line. What are the friggin' odds that BOTH of these, with pretty close serial numbers, would have a problem? I'll have to do the check you mentioned when I get them out of the Arms Room. Chris |
| Guys, mine does it as well, BUT ONLY WHEN BACKLIT. It is just a relection from an exterior light source behind the scope like PaulE says. I'd hate to see everyone send their scopes in only to have them returned with a note saying they passed Aimpoint's inspection. |
