Nautilus Rotating Rail

Ballista Tactical Systems has developed a rotating rail. The forward section of the rail can rotate in 45 degree increments with the push of a button. This can allow, for example, a bipod rotated around to 3 c’clock and a fore-grip rotated into the 6 o’clock position.

I think Ballista Tactical Systems needs to develop a new model where the forward section can be unlocked to rotate freely. This would be fantastic when using a bipod on uneven ground. Rotatable bipods are a feature of very high-end sniper stocks.

    i can only imagine the mall ninjas will now have reason to mount more stuff to their rifles. 4 different usable red dots? 4 different fore grips.

  • jdun1911

    I can see the uses in the future where firearms electronics accessories become the norm. But for $800 is a lot of money.

  • Jon Mac

    Why not go ahead and motorise it, incorporate some fairy lights, a thumping techno soundtrack…

    • Komrad

      I sometimes put on Oomph! or Eisbrecher under my ear muffs while shooting.

      • David/Sharpie

        When I go to the range alone I like to listen to music when shooting

    • WeaponBuilder

      This is BRILLIANT! We need a picatinny-to-picatinny adapter for this too…

      Put this on a rifle with a low-profile gas block, then I can mount a Daniel Defense quad rail to one side, a Troy rail to another, a VLTOR rail to another, and a Knights Armament rail to the last one!

      We’ll call in Xzibit, and he can pimp my AR! “YO DOG, WE HEARD YOU LIKE QUAD RAILS! SO WE PUT QUAD RAILS ON YOUR QUAD RAIL!”

      This way you’ll be able to shoot your rifle with whichever rail system is the flavor-of-the-week according to the online armchair commandos in Mommy’s Basement!


      This product is innovative, yes. Practical? Not really. Front-Heavy? Almost certainly. For $800 I’ll certainly pass. :-/

  • AZRon

    This is a wonderful example of engineering creativity. It is, however, far too tactical for my needs.

  • Michael

    Could have a use for Night vision and magifiers for red dots

  • MP

    Add a few more rings, number the sides, integrated gun lock, ????, profit.

  • David/Sharpie

    Seems like a useful idea, for certain applications, for the average gun owner I don’t it’d be needed.

    The girl in one of the pictures is kinda cute too!!

    But $800? I’d rather a bipod in front of a foregrip, rather than beside

  • Doug

    I could see mounting a 1-4x scout scope on a longer rail then flipping it out of the way for really close up shooting as long as it would hold zero. I would maybe pay $200 for it, but $800 is WAY too steep.

  • Chucky

    ALRIGHT!!! This is the perfect companion to the earlier featured Zombie Pistol Bayonet. Stick four of those on this rail on a 10.5″ AR-15 and jerry-rig an electric motor to the rotating part. It would make a chainsaw look like a butterknife in comparison.

    • David/Sharpie

      Haha yeah but the pistol bayonets wouldn’t go out far enough to stab anything

      • Chucky

        With a flash suppressor on a 10.5″ barrel, I’m guessing maybe only about 1/2″ – 1″ of the blade will be left sticking out. But with all four spinning around, stabbing isn’t exactly its forte anymore. More like coleslaw.

    • Liv

      Zombie bayonettes is bush league, mount multiple wakizashi or go with full fletched swords.

      • Chucky

        I don’t think rail attachable versions of those have been made yet.

  • Henry

    Hey MP,
    Regarding integrated gun lock…are you referring to a trigger lock or something regarding the gas tube?

  • Jeb

    I have one of these rails and I couldn’t be happier with it! Unlimited accessory options on a truly reliable base. I have put mine to the test in the feild and despite all the abuse it continues to function flawlessly! Yes it is a bit expensive but I believe in the (get what you pay for) philosophy. And if you want cheap equipment for your rifle there is always the pellet rifle section in your local Walmart.

  • John Doe

    This + electric motor + four lasers + four SureFires + four pistol bayonets = lighter wallet + fun

    • Chucky

      That won’t even fit anymore. You’re gonna need a 3-sectioned rotating rail. But why stop there?

    • JMD

      Why not just make it spin all the way around, motorize it, and cover it in blades? It’ll be like the Reaper from Perfect Dark.
