Check your red dot sights: September 2014 edition

| September 30, 2014 | 7 Comments

Hey folks, any time I pick up a firearm with a red dot sight on it I make sure it is working. I also check all the red dot sights on my firearms at the end of each month.

This post serves as a reminder for you to do the same.

Interestingly, I’ve yet to replace a battery on any of my Primary Arms MD-07 family of sights (seven and counting). Some have been on “1” (low) since early 2013.

The only optic I’ve had to replace the battery on is my Primary Arms Reflex sight, which I no longer use. Since I’ve taken the reflex sight off my firearms and put it on my workbench the battery has never died. It went through two batteries in less than a year, and now it’s just chilling in my dark basement going strong 18 months later. WTF. What a bitch.

All dots in the house are working, including the three kept on at all times on my rifles.

I keep my red dots at the lowest setting. I do this to preserve battery life and also from my experience in low light shooting training. The lowest setting will be plenty bright if your eyes are adjusted at night.

Did you have any dead dots in your house this check-up?

    The old green PA reflex sight was a bit of a dog for me, too… nice concept, but the FastFire III and RMR are worth the extra cash. PA made it right, as usual.

    The problem you’re describing with batteries is why I’ve made it a habit of almost always having two aiming methods on a gun – either co-witnessed irons or a QD mount for my optic, or in a real pinch, a laser sighting device. I’ve also started leaning more and more towards optics that can run without batteries… etched reticles (prism sights), solar powered, or trit+FO. All of those options have their quirks, of course.

    Its a good idea to have a planned check monthly, I will have to add that to my list.

    I do however, preemptively change my batteries on my red dots on my birthday. Just an easy day to remember.

    Good idea. I have a Holosun HS403A with 50,000 hours of battery life and a 8 hour shutoff. Primary arms sells them and I can recommend it if you would like a aimpoint t1 clone.

    “They passed 8hr submerged under water, passed 12 gauge recoil testing, drop test passed, freezing passed,heat testing passed, ran it hard on AK and AR and it has been on since the day I got it on High still running like champ. I really like the sight picture and glass on these. So far its my favorite out of all the red dots so far.”

    They also have free shipping off the manufacturer’s website. Quick too!

    All passed the first time around, but this time I had a dead Aimpoint M2. I left it on the highest brightness setting for a couple of months and that seems to have killed it.
