    So I pulled the off trigger and started to swap out parts. I had found a disconnector in my parts drawer, so I started there before i parted out my DD LPK for it's trigger. Low and behold that was it. It acts like the other triggers. I thought that that that can't be it, so I swapped the old part back in and the old behavior came back. Swapped the found piece in and back to normal. I wouldn't think that the disconnector would affect the trigger that way.

    Here are the disconnectors. The one on the bottom with the longer nose towards the top is the bad actor. The one on top was from my disconnector fairy that fixed it.

    Nice "crisp" 5lb pull, some overtravel and solid reset.

    Looking at the disconnector and googling 'ar 15 trigger disconnector' I found this suspect:

    https://www.amazon.com/AR-15-Disconn...ustomerReviews

    Which in turn led me to this:

    https://shop.tacticalshit.com/diconnector

    Which causes me to rethink things. I'm one that doesn't get as concerned about the label, but I do draw the line at sourcing parts off Amazon. Really Bro?

    Also a WMD NiB disconnector looked similar.

    Nice Google-fu. It does seem that the rounded ‘hole’ radius near the top is a distinctive feature. I just never thought that the disconnect or would have that impact- by itself. I assumed the hammer/trigger sear surfaces were the main culprit. Shows what I know. Glad I had three kits to work with. If that odd one had been the only one from PSA, I would have not thought well of their LPKs. Having to swap a part isn’t good, but all three lowers look and operate well now. I’ve got 4-5 lowers that don’t have uppers now..... 224V, a dedicated 22 upper... A2 uppers are old school now....maybe time for an SBR...
