Check your assumptions, dummy!

Another one of those busy days.

As you may (or may not) recall, I recently bought a new shooter, and before that, I bought a new optic and magnifier.

In my immensely clever way I told you that I'd had a disaster with the new optic, a Holosun Micro Red Dot.

The disaster was that the cement holding the objective lens in place failed, ruining the sight. I knew (assumed) it had failed because when I put it on the new shooter it wouldn't hold a zero, which was odd, because it had worked perfectly on the rifle I'd first mounted it to. I took a close look at the sight and noticed that the objective lens was tilted in the mounting, and I knew that wasn't right. I knew without a shadow of a doubt that it hadn't come out of the box that way.

So in the fullness of time I received an "are you satisfied and will you write a review?" email from Primary Arms, the supplier of the optic. I quickly replied, basically, "WTF, O?"

Well, let me show you the email thread.

Glad to receive your email and I appreciate your follow-up.

Here's the problem. I loved the sight out of the box and for the first 50 rounds.


After about 50 rounds the adhesive/cement holding the objective lens failed, rendering the sight useless.

I'd like to have it replaced because I liked it so much before failure, but I'd hate to get a replacement only to have it fail again.

What should I do? I read somewhere about a similar failure with a holosun sight. Can you reassure me?

(I attached a couple of pictures)


Hi Shaun, 

Has your red dot stopped turning on or is that lens moving? The cant in the objective lens looks perfectly normal. The cant on the lens is what reflects the dot from the emitter back to your eye, much like using your watch to reflect sunlight back into your buddies eyes.

Thanks for getting back to me so quickly. I didn't notice the cant until I mounted the sight on a different AR and couldn't get it to hold a zero. Let me give it another try and see if I was making an incorrect assumption.


Hi Shaun, 

Please let me know how everything works out. 


Thanks Marc,

Just back from the range. I'm very pleased. Got rained out before I could get it completely dialed in but it's holding zero nicely now. Must have had a bit of wiggle in the mount when I attached it the first time. Thanks for politely pointing out the possible flaw in my assumption. I'll be posting a review in a little bit. Here's 20 rapid from 200 yards from an impro rest. Rifle is an Auto-Lok AL-15 with 10.5" bbl shooting IMI sourced M855.

Thanks for your service, Army.

It was an honor to serve, Shaun! Glad everything worked out! That's some fine shooting! 


Of course Marc was laying it on a little thick about the fine shooting, but that's life in his line of work.

I'm pleased that the sight was fine and pleased at how well it works and even more pleased to have had, for the thirty-seven-millionth time, a silly assumption fail me.

In case you're wondering, I'd recommend Primary Arms and the Holosun Micro Red Dot sight.


  1. Great story. Loved the fact that they made polite suggestions and that you fessed up to maybe you screwed up.

    Sounds like a great outfit to buy from!

    1. I'm pretty pleased with their product and customer service. Sample size of one, but if Marc is a typical employee they should do quite well.

      As for fessing up, "when you're up to your neck in alligators..."

  2. Well, we all know what assume stands for. Another fine post, thanks.

    1. Yes we do! You'd think SOME of us would learn...

    2. I expect you to be perfect right after I become perfect. Don't rush, I have several eons of work before that happens.

  3. I am pleased that it worked out for you in the end. It shows that Ranchers shop better than Badgers do. I know of a Badger that paid almost as much for his EoTech sight as he did for his rifle, and you sight, when properly installed, does just as good of a job, at a fraction of the cost.

    1. So far so good! And I got the tip from Karl and Ian at InRangeTV. I was very close to pulling the trigger on an Aim Point PRO.
