SWR Radius Rangefinder (SilencerCo Weapons Research)

Now that I have started getting interested in precision long range shooting, I’m actively hunting for gear. While I have come to believe (and have been so instructed) that learning to manually range find is one of the core skills that all shooters should have (because electronic crap fails at the worst time), I also think that having tech is useful and can really increase efficiency and accuracy.

So today, a buddy of mine sent me a link to a new gadget from SilencerCo Weapons Research which is pretty cool.  It is a rail mounted rangefinder capable of ranging out to a mile on a reflective target and attaching to a Picatinny rail in any orientation.

It was developed to allow the shooter to accurately range find without having to come off the gun and still be affordable. And at $999, I think this is a good bet, especially for something that can range to a mile.  Most of the range finders I have been checking out only go to 1000m (though in all fairness the Radius will only pick up non-reflective targets at 1000m).

We did discuss the Sig Sauer KILO2000 Rangefinder (which can hit just shy of 2 miles on a reflective target for ~$500).  And for those extreme needs there is always the Meprolight Erbium Glass…  🙂

Here is a short video demonstrating a speed test between different methods.  I’m impressed that the manual ranging is nearly as fast as the handheld range finder (though this test would need to be independently confirmed and show repeatable results before I would believe the numbers):


Technical Specifications:

  • POWER: 2 CR123A Lithium Ion Batteries (Included)
  • HEIGHT: 2.30”
  • LENGTH: 5.80”
  • WIDTH: 2.96”
  • WEIGHT with BATTERIES: 18.2 oz.
  • WEIGHT without BATTERIES: 17.0 oz.

So what do you all think?  Useful?  Overpriced?  The big benefit to the Radius is that you don’t have to come off the gun to use it, so if you are speed shooting this would likely be a better choice than the Kilo2000. If I can get my hands on one maybe I’ll do a short review.

    I’ll wait for the gen 2 radius. Kind of disappointed that after all the hype SWR made, all they release is a range finder (albeit a nice looking one). Interested to see what else they come out with in the future.

      Pretty much, I can see ZERO reason to sell my Leica for this.

      • AndyHasky

        Embarrassingly enough I don’t even have a range finder, just borrow them from friends and family when I shoot, I could only see me using this while prairie dog hunting alone. But a $1k range finder on a $350 17 hmr seems kinda crazy…

    With a range finder it is easy to learn how to judge distance with no tools. Just try to guess distances and then use the range finder to get feedback. Try, fail, repeat till you don’t fail. You will get good at it in no time!

      I’m forcing myself to learn how to estimate with the reticle. Have to be able to read wind anyway… 🙂

    • CavScout

      I hope you’re kidding. Try all you want, you’ll be lucky to ever get it within 20+yd consistantly. At distance, that’s a big difference in the bullet drop. Your method would be good for learning to get very rough estimations, not really any more than that.

    How well can this range finder be synced with scope reticle so that its actualy looking at the same object?

    • AndyHasky

      I think its the same as a laser designator, instead of making the beams or axis of the two meet at any point, you make them parallel. so technically, the two will never be looking at the exact same thing, if the radius is mounted to where its offset 1.5 inches above the scope, then it will always be measuring the distance to whatever is 1.5 inches above your crosshair as your looking down the scope. If that doesnt explain it, TNVC has a video on youtube on how to zero an IR laser, same principle here I believe.

    any rangefinder for long range shooting MUST have bluetooth. then my phone can read it and pull up my load tables (with barometric, temp, altitude, and humidity) automatically for my loads. easy peasy.
