    Similar problems Armalite and Daniel Defence had.

      Considering that even the big name manufacturers have these issues, I am more terrified than ever to think about what happens when Bubba decides to DIY a milspec trigger job.

      • Bubba has a solid track record of polishing triggers into machinegun conversion kits by accident. Has for decades…

    • Emfourty Gasmask

      Prolly all used the same supplier 😛

      • Haulin’ Oats

        In the past Daniel Defense has been a big user of Geissele. But I think they might be making their own triggers now.

  • TechnoTriticale

    Who is the customer for these kits?

    These are standard (well, maybe) parts, and not racegun or mall ninja parts, right?

    If you own an M&P15, your lower presumably came with parts, and you might at most need one or two if you broke or lost something.

    If you don’t own an M&P15, what’s the scenario? For 80 percenters?

    • Joshua

      probably the 80% guys, people looking to make “cheaper” guns and people looking to make mil-spec guns and say they did it themselves

    • Nashvone

      My guess would be the first time builder. Someone that doesn’t know what parts are needed so they buy the complete kit. Since it says M&P on it, the assume it’s good stuff.

  • WeapTechMT

    They should recall the gunbuilder kit ones too (the ones minus grip/fire controls). The bolt-stop roll pin was so soft (on several of them) it was almost like rolled up aluminum foil. I work as an armorer/custom builder and have done hundreds of builds, so it’s not me. Had to use CMMG and LBE roll-pins to finish builds I started with these.

    Not really dangerous, but a little frustrating.

  • Cymond

    Wrong hammer? How was it wrong?
    Out of spec? Wrong gun model? 2-stage hammer in a single stage lpk? Full-auto hammer?

    I’m really curious about the exact nature of the mistake.

    • Matt

      Just missing the J pin spring

  • USAF Veteran

    I would guess that the part of the hammer the disconnector engages is out of spec and may allow the hammer to fall if the rifle is jarred or dropped.
