Thread: ULT on/off sticking

  1. #1

    ULT on/off sticking

    I picked up a ULE years ago with the ULT preinstalled from AGD. I aired it up last week and the on/off was sticking, so I gave it a little oil and it seemed to go away. Fast forward to tonight, getting it prepped for a big 24hr game this weekend, and while it fires, it is quietly leaking and sometimes it won't fire. This thing has a lot more moving parts (ULT) than my old Classic, so I'm not 100% sure what it is other than it sticking. If I pull out the ULT, is it supposed to easily slide in and out or is it supposed to be a super snug fit? Any input is greatly appreciated. Thanks!

    add more oil first , does it leak when you hold the trigger back ?

    I've added a substantial amount of oil, but it almost feels like I have to force the on/off in when I take it apart. I'll test out holding the trigger when I get home. Thanks!

    should be in the power tube , LX oring spacer , go 1 size smaller , there is a stickied thread on LX
    Also try fiddlin with your field strip screw ( do this 1st ) , sometimes 1/16 of a turn makes a difference
    And yes on/off orings fit snug , it's a good push with your thumb

    maniacmechanic: field strip screw didn't resolve it. trying to remove the spacer but it appears to be stuck, will find a way to get it out then get back to you. Thanks for the help.

    maniacmechanic: I have swapped spacers, and the o-ring in it, in the power tube, and it's still leaking. I was looking for the docs online but everything links to pages that are now removed on the AGD website since they redesigned over the past couple months ...

    This may or may not apply to you, cloper. I have a friend with a ULE RT PRO with ULT trigger and it developed a leak we could not seem to figure out. I gave it to a much more experienced Mag guy than myself, and he narrowed the leak down to some tiny little oring in the ULT trigger kit.

    In my opinion, the ULT trigger is nothing but trouble and I would avoid it if it were me ordering a new Mag.
