    ATTKTX ST LPR kit and Delta ZFR

    Hello all,

    Does anyone here have one of the ATTKTX Shocktech LPR kits? I will have one waiting for me when I finish this business adventure Im on. Wondering if there is a noticeable difference or just an overall opinion on the product.

    There is also a Delta ZFR in the box, so same goes for that one.

    Much appreciated and thanks

      The marker I ordered is at anno as well. Looks like we are in a similar boat.

    I have purchased four of the LPR kits so far. 2 are sitting in parts bins at Angry for builds I have in the queue.

    I swapped out the internals on one of my shocktech equipped trilogies. Other than improved aesthetics (it does reduce the profile of the LPR a bit) and maybe a bit of weight reduction I could not tell you if there was a performance difference (I did not put a gauge on the LPR).

      Awesome. Its been hard to find info on the performance of them, and the trigger. Thanks for the reply. At the very least, Ill have something else to tinker with when I get back.

    I have 2 kits. Waiting until after Scorched Earth this weekend to drop one in and I guess we will see, I also picked up one of those new 3 way shafts so might throw that sucker in there too. The other I was planning on putting in a desert fox Im waiting on from ST along with the ZFR.

      Bit of a necro, but need to correct my feedback on the LP kit for the FGP as used on my Impulse. That gun had a bad solenoid throwing all of this off.

      I back to back tested the stock FGP internals and the upgrade kit on the Impulse with the LPR mounted on the VASA (for maximum flow to the LPR). HPR is a PE SL3 at 170 PSI with LPR at 50 psi (lower tube is full NDZ). Powerhouse counterpunch reg set to 450 PSI.

      While I did not observe any changes to the required LPR pressure to get the gun running properly, the kit DID improve the recharge rate. Zero shootdown at 13 bps (did not test higher than this, I am sure it can handle a much higher ROF).

      Worth it.

      Not 1:1 to autococker relevance of course (eblade/racegun maybe) but still a data point.
