    Fluids still experience friction.

      Hydraulics experience so little friction in a system that small that it doesn't really factor in. The entire point of hydraulics is the ability to transmit force with minimal loss.

        Hydraulic systems as you're thinking of them are actively pressurized via motorized pump. Frictional losses scale with force and exposed area; losses are proportionally minimal because the force is many magnitudes higher than the area corresponding to the fluid-channel interface. They still experience friction, and unless OP is taping a hydraulic pump to his handguard that's something he has to deal with.

          Squeeze cocking. Hydraulic resevoir in grip. No saftey needed, dead trigger when not gripped.

          I think OP meant something more like the MAGURA hydraulic rim brakes for bicycles. Do those stll exist anymore or have they been replaced by disc brakes? I'm OOTL.

    Unironically test and patent that if it works

    wouldn't that give you the worst, squishiest trigger of all time?

    Leaks and utter unreliability.

      Not true for the hydraulic bicycle brakes I mentioned in my post above. Although a big problem might be that the hydraulic piston can get stuck to the cylinder a tiny little bit after it hasnt been used for a long time, that might make the trigger hard to control

      >unreliability.
      I find it fascinating that this is always the argument against new stuff, and it is always proven wrong, in the end. people forget that just 10 years ago, the AR was a shit platform that had to have super high end parts and be greased with unicorn cum to function correctly. now any clapped together franken psa build will run with the best of them. hell, grunts run around with Samsung galaxy's strapped to their chests and 10k worth of electronic optics. soon they'll be integrated power rails.
      a hydraulic trigger is the least of concerns here.

    If you are going to do a crazy hydraulic design why not just use electricity. Have the trigger be a switch. You can make it feel however you want. Hell you could probably make the battery last a month before you need to replace it depending on the firing mechanism.

        BBQ lighter triggers are fine for spud guns but miss me with putting one on a rifle!

    Same reason hydraulics are relegated to very specific used nowadays: maintenance and cost.

    A simple hydraulic like the one in chairs won't cut it for the constant pressure changes.

    Then you have really cheap hydraulics like the ones used in some ventriloquist toys, which have really shitty seals.

    Then you get the really expensive hydraulic links, and now you have the problem of actually getting them to fit in the gun.

    Honestly the original problem could be easily fixed if bullpup makers just had the balls to add a few more millimeters of room so they can use better trigger links.
