    ...just like a twig. Don't know what happened but it looks like a fairly cheesy piece of cast steel. Came installed on a SASS that's about 1.5 yrs old now.

    Fired flawlessly until this AM. I won't replace it with another...got a Timney on order.

    Anyone ever have a failure like this?

    Wow never seen a JP do that! I would send it in and see if they will send you another or refund the money.

    I am having good luck with Rock River match 2 stage in all my black rifles.

    No freakin idea. Put a hundred through it last week and this AM my cold bore shot flew high and the trigger wouldn't reset. Took it apart and this is what I found. I suppose I killed it.

    Never tried to adjust it either...felt great for a factory trigger.

    WOW!!! That's a new one on me!! JP triggers are generally pretty sturdy.

    You should see about JP warrantying the trigger. It sounds like you are moving to the Timney, but getting a replacement from JP and then selling it would help to offset the cost (or you can always go back to the JP if you are confident in it).
     
    Re: Freakin JP trigger snapped

    Cast steel sometimes fails like this but I didn't think these triggers were stressed too much. It looks like a stress crack failure. I'll def see if they'll replace it...can't be but a $5 part and a spare is always good. I have a hunch that I'll like the Timney better though.
     
    Re: Freakin JP trigger snapped

    had one happen like that too - was teaching a new shooter. He had a death grip on the rifle, and didn't take it off safety, before applying a Kong strength trigger squeeze. Click, snap.

    FWIW, JP warrantied and sent me a new one. I do like the triggers, but mine broke right where yours did.
     
    Re: Freakin JP trigger snapped

    Hmmm...strange. Mine came off safety fine and fired a round. Maybe it wasn't really a kong grip by your student...I've never done that to mine and can tell within the 1st lb of pull that I've forgot to kick it off. (Just thinking out loud)
     
    Re: Freakin JP trigger snapped

    You're always gonna have a bad one out of the thousands or millions they make . No one manufacturer is gonna have a completely perfect track record. I'd send it back to JP, they'll take care of you. If you don't feel confident about their triggers anymore, at least you can sell it. I'm sure it'll get sold rather quickly, it's quite popular.
     
    Re: Freakin JP trigger snapped

    I'm not sweating it too much but yes...not the best confidence booster when the go button.....won't go. I'll be reluctant to use another one even though as dlx stated, you're going to have failures. I do shoot the crap out of this thing so somethings gotta give sooner or later. I found a spare Stag trigger in my parts bin to hold me over for a few days. One thing I'll say is that the Stag trigger doesn't feel anywhere as nice as the JP did. It will be interesting to compare the Timney.
     
    Re: Freakin JP trigger snapped

    There was a post a while ago about this same thing . I am not sure if it was a JP or not but I believe it was because one or both of the adjustment screws was too tight . I tried searching for it but couldn't find the thread . I might have seen it on Brian Enos website though .

I've never touched my adjustments but when I took it apart the screws seemed too easy to turn, like maybe they moved due to recoil. Seems like something that would need lock-tite.

    Armalite or DPMS SASS? What is your rifle set-up? Were you shooting suppressed?
     
    Re: Freakin JP trigger snapped

    DPMS SASS, no modifications, around 1K rounds through it. No issues to date and no degradation in performance leading up to it. Just click and it snapped.

    <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: m_gale</div><div class="ubbcode-body">Take a look at the top of the disconnector. Is there an area on the tail just behind the "hook" where the finish is worn off?

    No supressor.

    There is an area on the disconnector with some minor wear, about in the area where the tail of the hammer would hit it.

    Contacted JP and they're replacing it.

    <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Awesymoto</div><div class="ubbcode-body">340 rounds down my DPMS SASS' tube and no trigg failure yet. Weird. Do you handload? possibly an increased bolt carrier speed might contribute to stress? otherwise no idea? </div></div>
    Just FGMM and M118, no homebrew. Technically the JP is a AR15 trigger so putting one in a .308 will net increased stress. If you look at the tail of the JP trigger where it meets the pin boss, it meets at a very sharp angle at the point of the break. I have a Stag trigger I'm using as a temp and that same area on the Stag has a nice smoothly blended fillet. It will be interesting to see if anything is changed on the replacement they're sending. If it looks the same I'm not going to risk another one.

    It's nice that they're replacing it but they're not sending a new one until they receive the old one so if it wasn't for my spare I'd be down for 2 weeks without a trigger.

    I bought a DPMS with a JP trigger installed by DPMS. I sent the lower to JP and had them reinstall the trigger. Much better when I got it back from JP. No problems on mine since. Other than Gorilla grip, I would look into the installation? Call JP and find out more just for the knowledge.

    I could see it being adjusted incorrectly from the factory. When I removed it I was able to turn the adjustment screws by hand which begs the question...did they move, and should they have had loc-tite on them? Either way if the Timney performs as well or better it will be staying put, if for no other reason than the simplicity of less to go wrong. I'll be carrying a spare in the field moving forward since a trigger that...won't...could be a very bad day.

    I have had JP install a few triggers and the adjustment screws have all been secured with red loctite exactly as the instructions dictate. It appears that is on DPMS.

    FYI the Timney is really not all that much more simple and they had some major malfunctions as well.

    Good luck,
