    A ULT Question

    does the ULT react slower than a standard on/off valve?

      Of course it works-its AGD

      Yes, it is slower due to the top area of the on-off pin being smaller which results in less force being applied to reset the sear assembly.
      Except for the Automag in front, its usually the man behind the equipment that counts.

          so it can't fire as fast or it just isn't reactive?

              it's not as reactive,less bounce

              you trade one for the other, reactivity or faster/lighter trigger pull

              however, if you put in enough shims you can sweetspot on the ULT

                  The number of complete cycles that can occur in a second is the theoretical maximum rate of fire for the valve. Increasing the cycle time will reduce the rate of fire. The sear and trigger won't return as quickly, so the total cycle time will definately be reduced. The reactivity is reduced as well, but some can be achieved if the proper number of shims is used.

                      is that why they don't put them in the E-Mags?

                          The emag sear assembly when connected to the solenoid plunger, increases the amount of mass that the pin must move when compared to the regular sear assembly. This slows down the action of the ULT even more. There definately is a rate of fire issue when used on the emag.

                              would any amount of shims make it work?
