DOCTER Sight C Reflex Sight

DOCTER is a brand of Analytik Jena of Germany, a high-end corporation specializing in analytical measuring technology, life science, and optoelectronics. At SHOT Show this year they were exhibiting their Sight C reflex red dot sight that has some impressive features. The DOCTER Sight C is specifically tailored to hunters, but has law enforcement, self-defense, and target shooting applications as well.

DOCTER evaluated many exterior coating materials to ensure the Sight C would endure in wilderness use, and selected Cerakote coating. The Cerakote coating is based on ceramics technology, and offers outstanding corrosion and abrasion protection. In addition, the extremely hard Cerakote finish provides long-term durability that has been tested to be up to 60% more resistant than Teflon coatings. Cerakote is recognized world-wide in the firearms community as an outstanding finish in firearms and firearm-related accessories.

The DOCTER Sight C is incredibly compact and offered in four colors.

The Sight C has easy to use elevation adjustments on the top, rear of the sight, and windage adjustments on the right side of the sight. The adjustment screws are flat-head, and DOCTER includes a screwdriver for adjustments. The adjustments make around .25 MOA adjustments per click, and there is a disc guide that is placed on the adjustments and screwdriver to clearly mark directional movement.

The battery compartment is on the bottom of the Sight C, requiring the sight to be dismounted to replace the CR 2032 battery. However, the Sight C has a small magnet in the mounting structure that aids in battery placement, and helps secure the battery during firing to ensure continuous and reliable sighting.

The advertising is heavy on hunting, but law enforcement, target shooting, and self-defense are all options for the Sight C.

There is no mechanical on/off switch. Using integrated control electronics the DOCTER Sight C automatically adjusts the sight brightness based upon the lighting facing the shooter’s target. There is a light sensor on the front of the sight that controls this feature, so any other rifle accessories cannot block that sensor for proper optic operation.

DOCTER provides new softcovers standard with each Sight C to help protect optical glass from weather or impacts during use, as well as an extra layer of protection when storing firearms. These softcovers come with an integrated “flipping lug” that allows a shooter to quickly remove the covers if a shot is needed immediately. There is an integrated 4-point loss protection that fixes the cap to the DOCTER®sight C, which effectively prevents pulling the cap off without using the flipping lug.

The soft covers come in black and safety orange.

Soft covers come in savage stainless & safety orange. Note the quick “flipping lug” at the rear of the cover.

Placing the softcover onto the sight will turn the sight “off”, until removed and the sensor will then turn the sight “on” to the appropriate brightness level. The Sight C does not have a diopter adjustment feature, so slight differences in optic sight appearance may occur due to nature human eye deficiencies.

There are several mounting options for rifles, shotguns, and handguns, including Weaver style mounting. DOCTER provides a guide on which mounting plate to use for each available option. There are handgun options for Sig Sauer, Glock, S&W, CZ, H&K, Walther, Colt, BO-Mar, and neutral.

If there was a specific area of the firearms market that saw a large introduction of new products at SHOT Show this year it was in the category of optics and sights. In particular, the popularity and rapidly expanding market for red dot or reflex optics, brought about several new options. The Docter sight C appears to be an excellent option in the area of reflex sights.

    Auto brightness sensor = pass from me. Last anything I had with a brightness sensor would not turn on at all in a semi dark indoor shooting range.

    • Not to mention that it has locking screws, which are now rather passe.

    • Steve

      It actually works quite well. I’ve got the old 2nd gen model and the battery has lasted years. This is the 3rd gen that has been out for a few years (with Cerakote being the only new addition). Never had any issues seeing the dot indoors or out. Aside from minor 3rd gen upgrades, this is the same exact sight that Docter Optik has sold successfully for years. It’s a very simple design; not as rugged as the Insight/L3 MRDS, but it works (even with the glass scratched/smashed/etc.).

      In this form factor, the only three red dots I would consider are the Docter, the Insight/L3 MRDS, and the Trijicon dual-illumination RMR models. I believe the Docter was actually sold under the RMR line in the U.S. at one time.

      The brightness sensor on the doctors has worked flawlessly on all the Docters I had (I, II and III). There is a minimum brightness, so the dot will never go dark due to the brightness sensor. Don’t know what crap you had experience with, but Docter is the opposite of crap.

    • My Burris FastFire (gen.I) has an auto brightness sensor that works fine for me, whether in a semi-dark indoor shooting range or outdoors in bright sunlight.

      What’s worse, in my experience, is when you have manually adjusted brightness, and the sun is going in and out from behind the clouds. So you’ve either got a dot that’s too dim to see, or too bright, and it’s flaring.

  • Crumbo

    I wonder how they mount it to a Walther and what model of Walther they’re talking about. If the only way is to get a bridge (that attaches to the picatinny rail under the barrel and comes up the side and provides a picatinny rail on top), that’s flimsy.

      You can mill a PPQ, but it’s dumb to do so

      • FightFireJay

        “but it’s dumb to do so”… Please explain.

        • JumpIf NotZero

          Because the PPQ is not a gun that takes well to customization. The slide is not readily replaceable. The slide is not thick enough to mill out and keep great integrity. It makes almost no sense to me to take a high bore axis and stack a sight on top of that compared to a gun you can hold lower when looking through the optic like the Glock or M&P.

          Compared to other platforms that do take better to having an mrds, the PPQ would be dumb to go through all the extra work for.

          • Kelly Jackson

            Why don’t you tell us how thick the Glocks slide is compared to the M&P and PPQ unless you’re just making up nonsense, AGAIN.

    • Tiru Maru

      They are talking about the P99

      • Crumbo

        My carry gun is a P99 w/ decocker and I’d like to have a reflex sight. Do you know how it attaches? If the slide has to be milled, that might only be possible on models w/o a decocker.

        • Tiru Maru

          Not sure. Mine is PPQ and the slide tapers to about a half inch on top. You may have to find a mount that attaches to the frame.
