Ultradot (The Best Little Red Dot You May Never Have Heard Of)

I had never heard of Ultradot before today and am now very interested in giving their products a run.

Ultradot has been around since 1989, producing their sights in Japan, and sponsoring an NRA Team at Camp Perry.  They had seven offerings at SHOT, and are in the $165-$300 price range. They keep prices low by not heavily advertising (and so pass the saving to the customer).

The Original Matchdot features four dot sizes (2, 4, 6, 8 MOA) at 100 yards.  It is 5.1″ long and wieghs in at 5.1 oz.


The Classic Ultradot (picture is the featured image for this article) and is their original model.  It is 5.1″ long and weighs 3.9 oz can comes in a 25mm and 30mm tube finished in black or silver satin.

The HD Micro is their newest sight and has “Pulse Width Modulation” (which is a super fancy way of saying “insane battery life because engineers figured something new out”, basically it is a power modulator to the LED that significantly reduces power consumption).  It also boasts an auto-off feature, brightness control and memory, a 2 MOA dot, and a built in rail clamp.


The Ultradot Pan AV a compact, lightweight waterproof and shockproof sight and will naturally achieve co-witness with standard AR sights.


The Ultradot L/T is a high performance sight that is water-resistant and has a 4 MOA dot with an auto-off feature, brightness control and memory, and a built in rail clamp.


The Ultradot 6 is their “tactical” model.  It has four dot sizes (2, 4, 6, and 8 MOA @ 100 yds) and two reticle patterns.  Elevation can be easily adjusted with a compensation knob.  It comes as either a 30mm or 37mm tube, and has precision windage and elevation adjustments at 1/2 MOA/click.


The Matchdot II has four dot sizes (2, 4, 6, and 8 MOA @ 100 yds) and two reticle patterns and only comes in a 30mm tube.


Overall they are a pretty neat company, and I look forward to trying out some of their products.

    Outside of Las Vegas – us uplanders call image #1 a $50 Millett Ultradot SP1. I think they are the OEM for Millett. The combination of an SP1 and a Ruger 22/45 get you bullseye 10s all day long. It’s the best red dot I own.

  • whiplash

    Bullseye shooters have known about ultradot’s quality for years.

    • Captain Chaos

      First time I’ve read about them.

    • Doc Rader

      Yeah, the rep I talked to indicated that they are very popular on the bullseye forums.

  • Blake

    Thanks for the heads up!

  • Guest

    Maybe I’m missing something, but what do you mean by x

  • Will Krause

    Maybe I’m missing something, but what do you mean by “x MOA @ 100 yds”? A minute of angle is a minute of angle regardless of what distance you are at.

    Is this the manufacturer’s terminology or yours?

    • Ryan

      Going off of limited knowledge here but I think it means that at 100 years to dot size is equal to 2 MOA. So if your target is 100 yards away the dot represents a 2 MOA area on the target.

      • Doc Rader

        Yes. The size of the viewed dot is larger. Think of it like the “big dot” sights. It would allow for faster acquisition when shooting closer targets. You wouldn’t want to use an 8 “MOA” dot for anything less than an 8″ target at 100 yards (extrapolate the math from there).

        I’ll stop back by today and see if I can get some pics through the optic with the different sizes.

    • Sadler

      Nowhere on Ultradot’s site do they say that, so it’s on TFB’s end, or the company spokesman misspeaking. They do mention adjustments and parallax at 100m though, so that might be the source of the error.

    • darthcoder

      It sounds like it’s selectable (and likely brightness related) – get a brighter dot? Well it’s going to be 6-8 MOA at 100y.

  • Tommy Huynh

    The level of poor writing here astounds me. Author claims it’s “The Best Little Red Dot You May Never Have Heard Of” yet provides no information on what makes it great, other than throwing in tech jargon which he clearly doesn’t understand and cites “insane battery life” which is about as useful as telling is what cereal he ate this morning.

    • Doc Rader

      Thanks for the compliment! Not sure what “tech jargon” I clearly don’t understand–could you please elaborate?

      I realize “Best” is subjective, but they do sponsor a winning NRA team that uses their product, and comes in at a price point well lower than others.

      I could have posted side by side comparisons with other vendor’s similar lines, but these are meant to be quick overviews (at SHOT), not full T&E reviews.

      Re: battery life: I was given a number of hours based on power consumption against the circuitry they’ve engineered, but was also asked not to publish the number since it hasn’t yet been reached (based on when it was released).

      • Tommy Huynh

        PWM is nothing new, in fact it is often considered the cheap route in dimming LEDs since most LEDs become less efficient with increased forward current (past nominal).

        • Doc Rader

          Point. I should clarify it is a new addition to their products.

  • ruinator

    Wow…it is a red dot I have never heard of. You say it is good. I guess the write up fulfills the claim in the title

  • Alex Pei

    Interesting. I’ve been wanting to run an offset MRD with a magnified optic and the options I’ve been considering up till now were the RMR and T1. May give the L/T a chance after seeing some more reviews.

    • Doc Rader

      Hopefully after SHOT we can get one in for T&E and put it through the paces.

  • uisconfruzed

    The first picture looks identical to my 20 yr old Tasco dot sight that I’m still shooting golf balls at 100 yrds with my 22.

    I don’t post here much, but I have never seen a bigger bunch of negative, wanna be’s, has beens, and glass half empty people. Constantly critiquing one of the best sites for firearm related news with knitpicking. You may be hungering for respect in life, love, or profession, but belittling others is not going to make you any more superior, just a jerk. Its not like you are paying to read TFB, enjoy it for what it is. a great, free, resource. Keep up the great work TFB! Its easy to be a critic not a creator!

    I’ve had an ultra dot II for about 3 years on a buck Mark pistol. For the price, it’s pretty amazing. Not sure if they’ve changed or if the review is wrong, but mine has 6 different reticles, not 2. Also has an adjustable elevation turret that can be zeroed, which is nice for dialing in quick range adjustments. Battery life isn’t Aimpoint good, but it’s okay. If you forget to turn it off, it will be dead the next time you use it (well, if it’s more than a few days).
