Expert Review

High-quality, rugged, and robust red-dot.

by Matt S., Gear Expert from IL, United States Written on April 15, 2022
The DRS is every bit as rugged as the Eotechs and has the option of single or multi-point hold reticles but also has slightly better battery life. Even though the Steiner isn't technically a holographic, the reticle projection is still very crisp and glass quality has the hallmark premium clarity that Steiner is known for. I prefer the DRS's combo of the large dot/small dot reticle compared to the donut of death on the Eotech, I feel it makes it much easier for quick acquisition.

In comparison to Aimpoint, the Steiner has a larger sight picture and already comes sitting at absolute co-witness height. It has a magnesium body and appears more armored thus more able able to take punishment than your average T1 or T2. The power and brightness control buttons are tactile and easy to manipulate thanks to the soft-touch silicon texture that's been applied to them. The NV capable settings also make this an ideal passive aiming option to complement an active aiming tool like the DBAL laser.

The battery life, rated at 2,000 hours, is adequate for most purposes. It's not the greatest battery life available for a red-dot, but considering that it runs on AA batteries which are easily sourced compared to CR123s...you'll hear no complaints from me. The 13 hour auto-shutoff also helps to increase battery life but I wish it had the option to adjust the delay time. The mounting lug is easy to use and tighten, although I do wish there was a QD option available.

All in all, the Steiner DRS...

Most Helpful Positive Review Great Optic
(Barely) Negatives: I'll have to get the QD mount eventually: The knob isn't so bad, but you have to really tighten it to get it on there properly. The actual red dot is rather high up in the FOV compared to a centered EOtech or Aimpoint. It could maybe be nice to get different color reticle options...

Most Helpful Negative Review Not suitable for daylight use.
Sold cmy EOTech and purchased this optic for pistol caliber carbine competition. The large single dot for close fast shooting would have been ideal as a solution to the need to hold several inches high on close targets. Unfortunately these competitions typically take place during daylight hours. In ...

premium optics no frills

by jayceeCA2A, Verified Owner from CA, United States Written on June 19, 2021
I'm surprised that there's only a few people have actually reviewed it and this sight isnt exactly new. Its been on the market for at least a year and half if not two. A previous version had buttons on the side while this new one has the buttons on the top.  My choices narrowed down to either the LCO or this DRSX1 and I chose the DRSx1. The sight is simple no frills in my opinion when compared to some others in the market. Though i would have liked to have auto on instead of the auto off this sight has.

The fov is great very wide.and uses 2 AA batteries but will run on only one, not sure why they designed it that way but i onky have one battery in it, granted run time is reduced with only one battery.  The sight is very well made and its made in the USA.  The design is very low key and iant market up with branding an logo like most others. You wiuld have to look real hard to find the very subdued Steiner printed on the sight.  But for the premium price of $650 -$700 it is not that good of a deal. At that price it should have some of the more advanced technology such as auto motion on, it has the off but that's pretty standard.  No covers for the lens, no micro fiber lens cleaning cloth, comes in card board box instead of a plastic storage case. But those are not deal breakers because they are not necessities  the sight basically doesnt come with anything you dont need but comes with 2 Energizers that you do need.

I usuallly use it at in door range in the aecond to lowest se...

Brick house

by Will, from AR, United States Written on February 10, 2021
Yes, she's thick, but she weights under 11 ounces, is nearly perfect in screwing things up close and personal. Best glass, great warranty, and double A batteries. Made in America. The 2000 hour battery life could be much better, but with 2000 hours on double A batteries buy 8 and bet set for years.
Pros:
  • Best sight picture
Cons:
  • None
Best Used for:
  • Shooting stuff up close
Would recommend: Yes

Great optic

by Geezer, from NH, United States Written on December 5, 2020
Great quality optic. It’s plenty bright enough for any daytime shooting I’ve done. Not a huge deal for me but mine did come with some scratches on one side. I was also a little worried about the batteries setup and location but zero problems so far.
Pros:
  • Quality build and longer battery life than Eotech
Cons:
  • None
Would recommend: Yes

THE RDS to have, but useless outdoors

by Moraa Koraa, Verified Owner from KS, United States Written on November 14, 2020
I bought this sight several months ago with very high expectations. The look, feel and feature set were perfect. Build quality is what I would expect from Steiner. Unfortunately the sight is too dim. I sent the original purchase back to Steiner (Burris in Greeley CO) three times with hope that each time I was given a return it would be "useable". No joy.

The issue I have with this sight is it is not useable in bright, outdoor conditions. Even on the center dot only reticle it can't be seen in direct sunlight against a light target. Look at the (three) video reviews of it and they are all shot in cloudy or indoor conditions.

I really wanted to like this sight but it has to go back as it is simply unusable (for me).

I would recommend the proven MRO or Leupold products over this.
Pros:
  • Build
  • Sight Picture Crystal Clear
Cons:
  • dim dot
Best Used for:
  • Indoor and low light self defence
Would recommend: No
