That’s What She Said: Meprolight Mepro Tru-Dot RDS Review

| September 9, 2015 | 9 Comments

The Mako Group, importer for Meprolight, sent over their Mepro Tru-Dot red dot sight for review.




  • 1.8 MOA red dot
  • Powered by a single AA battery
  • Two throw levers on an integrated rail for easy on-and-off of a standard Picatinny rail
  • Wide optic window
  • Sealed unit for weatherproofing
  • Compatible with night vision goggles (NVG)
  • $399.99 MSRP


I ran the Tru-Dot through eight hours of a basic rifle class followed by eight hours of an advanced rifle class for a total of sixteen hours of very active testing.

I went through about 750 rounds while testing the sight through everything from hostage drills to one handed drills around barricades with my off hand. I even shot the hundred round drill twice to see if the repeated concussion would affect the zero…and also because fun.

Here’s what I came away with:


  • Close to zero out of the box
  • Easy to find dot
  • Easy to install
  • Red dot did not fracture in the sun
  • Runs on standard AA batteries
  • Quick release
  • No mount needed


  • Offers only 3 levels of brightness + night vision mode
  • Bright level selector was opposite from other sights I’ve used which caused some confusion at set up
  • Occasionally the dot was’t present until the sight was jogged by firing
  • Ran out of battery life midway through the second class

Overall I really liked this sight. The window is large and hooded, but not so oversized that it interfered with my sight picture when shooting off handed, prone or around barricades.

While it’s nice that there was a AA included with the optic, I recommend using a fresh battery from your house instead. The included battery died after about 12 hours of use. Since Meprolight claims “thousands” of hours of use, I’m blaming the battery.

I wish there were more brightness settings. The emitter was high quality, and the red dot was nice and round. This is something I dislike about the Primary Arms MD-05 that’s usually on my rifle.

Overall, I would recommend this optic for someone who wants standard battery compatibility, easy installation and setup, and durability.

Short Barrel Shepherd says:

I was impressed with how sturdy the optic was, and I liked that it didn’t require a rail. I also liked that it was almost dead nuts accurate right out of the box on She’s 11.5″ barreled SBR AR15.

While the red dot was more distinct and uniform than the Primary Arms optics we run, the Tru-Dot was not nearly as bright.

I personally dislike the auto-shut off function, and wish there was a way to disable it. We leave the optics on at all times on all of our defensive rifles. Since we check our optics monthly, I don’t mind changing batteries if that means one less thing to worry about when I need to use the weapon.

I think the biggest is price. The Tru-Dot compares to similarly priced optics like the Aimpoint PRO. If the Tru-Dot were a little less I think I’d be more inclined to recommend it. I do realize the night vision compatibility adds to the cost, but this feature is not useful to us. This puts the Tru-Dot in a no-man’s land between Primary Arms / Vortex optics and Aimpoint and Eotech offerings.

However, The She-Shepherd liked it, and prefers it over her Primary Arms MD-06.


The Meprolight Mepro Tru-Dot RDS was provided to us by the Mako Group for testing and evaluation.

    This is surprising to me, and I have not experienced that problem on my Tavor, which is where I run mine. I am thinking battery problems, or maybe the battery compartment wasn’t tightened down enough?

    I will definitely agree that the brightness knob is counter-intuitive, but I just set-and-forget.

    (My own review is linked to this post.)

    Do you have any buds with astigmatism?

    I’d like to see how it compares to Aimpoints for astigmatism.

    • CR Williams says:

      I had astigmatism and have both an Aimpoint and a Meprolight (Meprolight is for sale, by the way). Before I had LASIK correction I experienced blooming or separation with those and any other red dot I have. Not as much problem with green as I recall. Since the procedure (a month ago now)the dots are still not sharp but are much clearer and more distinct and there is no separation.

    • Short Barrel Shepherd Short Barrel Shepherd says:

      She Shepherd and I both have astigmatism,both marginally corrected by glasses and contact lenses, respectively. I found the dot more “round” than our Primary Arms sights and the Trijicon RMR RM07 sights.

    • The She-Shepherd The She-Shepherd says:

      I’ll see your astigmatism and raise you some farsightedness…

      I find that mounting my sight a little further out on the barrel each year helps with the latter. As for the former, the Meprolight did seem more easily visible to me.

      I am also considering ordering some prescription eye protection.

      • CR Williams says:

        Give serious consideration to LASIK correction. I should have done this a long time ago. Thing I like most above much better definition on sights (Glock front sight posts might as well not have been there before this) is the elimination of the risk of losing your glasses while having to function in some emergency situation.

  3. Thomas McClimans says:

    I’ve been using several the RDS’ for nearly a year now since they first came out. While I, too, would like to see a slightly brighter max level, the dot has always been quick/easy to pick up even in bright Idaho sunlight.
    The only problems I’ve experienced to date have been one unit flickering on/off from recoil, that was due to my not having the battery cap fully tightened. The other is the switch very occasionally rotating to the off position from rubbing against my gear when doing sloppy transitions.
    I can take or leave the auto-on/off feature, but it is a nice way to have your optic instantly ready to go 24/7 w/o affecting battery life or LED service life.
    At this price point (as low as $335 on Amazon), IMHO the RDS has a lot to offer and few drawbacks.
