KDG Recognizes the Seeming Absolute Co-Witness Community with new SIDELOK

Kinetic Development Group, still at it with their excellent SIDELOK series has seen fit to recognize what seems to be the minority of the AR-15 shooting community. With almost all manufacturers offering lower 1/3 optics mounts, those of us steeped in the classic cheek weld versus the morally and physically inferior chin weld now have a Q/D option for the excellent Aimpoint Micro series of optics and its constituent clones.

I mean, who, in their right mind, would seem to remove contact points from a weapon system? What deranged soul thinks that the small perceived benefits of permanently deployed iron sights taking up a smidge of their vision is a good trade for a poor head position. This is not to mention the profoundly misguided folks who use lower 1/3 without permanently deployed irons. The horror!

(For those who missed the humor in this article, I pity you).

Fortunately, Kinetic has seen the light and applied their novel SIDELOK system to true believers. As with its wrong higher cousin, the SIDELOK system is truly quick detach and by using powerful springs, keeps zero and the optic held on tight.

For those looking for a Q/D solution, the SIDELOK Aimpoint Micro Mount – Abosolute Co-Witness is available directly from KDG and through their dealers. MSRP is listed at $139.

    AK’s have brought me to enjoy a chinweld. Feels like more leverage to pin the rifle in place.

  • Russ Kell

    My operator beard gets caught in things if I chin weld.

    • Phillip Cooper

      Real operators don’t whine about a few pulled hairs. Suck it up, Francis….


      • QuadGMoto

        LOL! (For reals!)

    • TexianPatriot

      I see an opportunity to bring a new product tp market. Operator Beard Protector, OBP, because operators love acronyms. This industry already has many other crazy products. Why not?

    Opinions are like behinds. Nathan would do well to remember this when writing future articles.

      You prefer absolut?
      The only benefit I see with absolute is that you can almost use a round optic like an aimpoint micro as a large ghost ring

      • FulMetlJakit

        Their Peppar is good, but I prefer Sobieski, or Tito’s.

        Ugly Dog is great if you can find it.

      Lighten up francis

  • NMac

    I see this at home on a 9mm SBR build. Something like a CZ Scorprion.

  • John A. Smith

    Interesting. It had never even occurred to me that anyone would ever set up their sights for anything but “absolute” co-witnessing. Hell, I didn’t even know there were words to describe either.

  • Joe

    Nice. Glad to see a mount that doesn’t look as high as a kite.

  • Phillip Cooper

    Well, anything to fill the article feed…

  • glenn cheney

    Publish or perish.

    I prefer lower 1/3 because:
    1. It gives me better awareness downrange
    2. I can pick up the sight faster when standing
    3. Earmuffs aren’t squished into the stock as much
    4. My neck and head don’t have to scrunch down as low

    I really don’t understand the paranoia. If your sight fails, which if you bought smart should almost never happen, just throw your QD lever and you’re done. Or skip that step and just aim through the lower 1/3 of the tube.

    Geez! Lol.

      not all optics play nice with zeroing at 1/3rd, many will distort the image of the front sight post, so zeroing through the optic, and then removing it, your poi moves, similarly, zeroing with optic off and then shooting through it using irons, moves the poi. Not all optics do this, but you should be aware of whether your optic is one that will cause this.

  • QuadGMoto

    What about those of us with long necks? I almost feel like a giraffe drinking water when I do a full cheek weld on most rifles.

  • DanGoodShot

    So… when will there be one of these absolute co-witness mounts for the comp m4?? Thats what I’m waitin’ fer.

  • int19h

    Is there any reason to NOT do absolute cowitness when both front and rear sights are folding? When you don’t need the irons, they are out of the way, so it doesn’t matter; and when you do need them, you get a better sight picture.

    • iksnilol

      What if they aren’t folding?

      • int19h

        Then it’s a different matter. That’s why I included “when they are both folding” in my question.

    • Running two different zeros, 25yds with the irons and 100yds with the dot for example. Slightly less cluttered window, but I when using the dot tew correct way I don’t even notice the irons no matter where they are.

  • Blake

    Oh thank god. Hopefully more MRO mount manufacturers will do the same. The Troy mount is everything I could hope for in a mount but they don’t freaking make it in absolute cowitness! All I want is an AC MRO mount that is cantilevered and doesn’t look like a rectangular block of metal!

    • HSR47

      I waited over a year for Larue to come out with an absolute co-witness mount for the MRO; I finally bought one of Geissele’s absolute co-witness mounts and I haven’t found anything to complain about yet.

  • pun&gun

    Good to see. I hate using lower 1/3.
