Meprolight TRU-DOT RDS Battery Powered Reflex Sight

This is a TFB exclusive preview of the upcoming Meprolight (Mepro) TRU-DOT RDS battery powered reflex sight. The Mepro TRU-DOT RDS is a lower cost commercial version of the Mepro M5 reflex sight (TFB preview), which it was developed as the successor to the Mepro M21 (TFB review). The original criteria for the M5 called for an increase in the field-of-view, adjustable illumination levels and a price of $400-$450. However, when the IDF (Israeli Defense Forces) took an interest in the M5 they requested a number of expensive features added. All of that led to a 2-years extensive field trial and the price has shot up to $625, which is now more expensive than the Mepro M21.

The new Mepro TRU-DOT RDS derivative will be offered only in the U.S. market for both commercial and law enforcement sale. The good news is that the MSRP will be back to under $400, most of the upgrade features from the M5 are retained.


Externally, the Mepro TRU-DOT has the similar viewing window layout to the L3 Communications EOTech sights.  Besides the external look, the Meprolight design is vastly differ than the EOTechs. Size wise the Mepro sight is smaller than the full-size EOTech 550 series but slightly longer than the EXPS series, although not as wide as the EXPS.


A departure from the traditional forward circular, ocular Meprolight design is the use of a rectangular vision window on the M5 and TRU-DOT RDS. The rear located ocular window offers a big improvement in terms of a practical field-of-view. Also shown on the right side are the adjustment nuts for the built-in dual QD levers.


The standard AR-15 iron sights will co-witness with the Mepro TRU-DOT RDS sight. I would say it’s more of a lower 1/3 co-witness, which most shooters prefer. (shown with the Midwest Industries SPLP flip-up rear sight). The IWI Tavor bullpup with its taller backup sights should have a near perfect co-witness with the Mepro TRU-DOT RDS.


The reticle is a 1.8-MOA red dot powered by a single AA-size battery. In the original design criteria, the battery life is 4000 hours. Then it jumped to 8000 hours when the IDF got involved. With the latest micro-processor managed illumination technology upgrade, the Mepro TRU-DOT RDS’s battery life is now 15,000-18,000 hours on maximum brightness from a single lithium AA battery. That’s further extended by a motion sensor activated power saving mode.


The major differences between the new Mepro sights and the EOTechs is the illumination of the Meprolight is by LED, while the EOTechs use laser projection reticles. The internal optical design is also completely different. The EOTech uses multiple mirrors or small prisms with lens, while the Meprolight features a single large prism that also makes up both the front and rear lens. From what I found in reviewing the Mepro M21, the choice of using this large piece of hardened optical glass has probably helped significantly in getting the M5 to pass the IDF’s MIL-Spec requirement.


One of the major cost reduction features is that the Mepro TRU-DOT uses a plain polymer hood, instead of the machined aluminum hood found on Mepro M5. Although, this change makes no difference in the drop-test rating of the Mepro TRU-DOT sight.  I suspect that its large hardened optical glass prism probably has something to do with it. The new notched illumination control wheel also helped in lowering the cost, and I like it better than the Mepro M5’s machined controller wheel with small slots.

Some of the expensive IDF requested upgrades that have been retained are the dual low-profile QD throw levers, the extensively tested night-vision equipment compatibility (Gen II & Gen III NVG), and the built-in motion sensor for the automatic wake-up function.


The Mepro TRU-DOT RDS will be release in the U.S. on August 15th. As a launch promotion, Meprolight’s American distributor, the Mako Group, will release the first two hundred Mepro TRU-DOT RDS sights with an aluminum alloy hood installed. It’s available for pre-order from IDF Holster’s pre-order page with free shipping.

Update: Due to the recent conflict in Gaza, the manufacturer had delayed the shipping date to mid-September.

    Looks kind of bulky, but it doesn’t need a riser mount on an AR15 so there’s that. The auto-wake function is great, even with a 2-year constant on battery life. It weighs the same as an eotech 550, decide if that’s good or bad. It’s clearly competing in the same class.

    I still kind of expect a full reticule out of a high end reflex sight these days but I guess that’s what you get with LED vs laser.

    • Timothy G. Yan

      My EOTech 553 SOCOM weights 13+ oz. with the build-in QD levers and riser. The Mepro is suppose to weight 10 oz. or less with QD levers. There are few reflex/red-dot sights that have full BDC reticule but those are made for crew-serve weapon or auto-cannons. Those are big and expensive and not available in the commercial market.

      • Shadow

        All of EOTech’s BDC lines are available to consumers AFAIK.

      • sianmink

        All I really want is a horseshoe. XD

  • Christian Hedegaard-Schou

    Seems unfair to keep comparing this to an Eotech when it should be compared to an Aimpoint. If it used a laser and had an actual reticle other than just a dot, it would be a fair comparison. This is way more similar to an Aimpoint in operation than an Eotech.

    • Timothy G. Yan

      It’s very different from the Aimpoint’s tube body design as well. Anyhow, since it does look like an EOTech, people will try to comparing the Mepro to it.

      • gunslinger

        my kid has a porche power wheels. should i compare it to other power wheels or a real porche because they look the same?

        • Ben M

          If this were some chi-com airsoft sight, that might be a fair comparison. It is a military grade rds, there are only a handful of sights that you could fairly compare it to. The eotech and aimpoint sights are both more similar to the Mepro M5 than they are to each other, but that doesn’t stop people from comparing the two constantly.

  • I want to put this on my Tavor. Right away.

  • Cornelius Carroll

    Ordered 😀

  • erwos

    I heard this thing only has four brightness levels – how did you find them in use?

    • 7.62 Precision

      Yes, it really simplifies it. It is one of those things that becomes a marketing race – manufactures brag about how many brightness levels their sights have, and no one stops to ask, “Why?” One of the things the IDF said they were looking for was simplicity. Why have 64 levels of brightness when four cover everything you need? With the RDS, when stepping out of a dark building into a bright desert street, you can move the switch one click, instead of spinning a switch around or push, push, pushing a button and checking the sight until you get the brightness level you want.

      • erwos

        I don’t mind only three levels – the question was more whether they chose the right three.

        Personally, I am really liking the value proposition this optic offers, and will be buying one for my Tavor. The hood looks like it’s held on my some Torx screws – I wonder if GG&G or another vendor will do a replacement hood with flip-up covers.

    • Timothy G. Yan

      I am a simple guy. The NV, low, med, hi is enough for me. Low setting for night and the Medium setting for day. The above outdoor shot has the high setting, which has too much glass reflection for me.

  • TangledThorns

    If I had a Tavor I think I’d get this sight for it. I have an EOtech, it’s nice but I like to try out other products too.

  • LE6920

    I have one on order. Looks great. What I really want is the Marine Corps emblem on my rifle.

  • Jim

    Just got mine today and installed it on my DD rifle. Looking forward to sighting it in and putting some rounds through. I ordered in August and I believe it will have been worth the wait. I received the Alum. Hood version. I expectations are function over form. I would like to beat up this red dot which I will and see if it holds up. Later., I will be looking at a Vortex 3x magnifier. I can get one for under $200, which my budget can handle. I will not pay as much or more for a magnifier as the dot sight. Simplicity is the key for me.
