    They stabilize the pins by making the whole unit act as one.
    Damn I didn't even think about field repair...I put them in so long ago, I forgot they used allen heads. My "go-to" rifle won't have them in that case...

    KNS products are all pretty retarded.

    It's your lower OP. Try the rifle with and without. You decide. Don't let some internet Einstein decide what flavor of kool-aid you should drink. Jim Jones got lots of people to drink his kool-aid.

    Didn't you know you have to have them to be a real deal "operator"? They will make everything in your world better
    Actually, I HAVE found a good use for them. I have them on my sbr b/c I use a Chip McCormick trigger and it had little clips to hold the pins in.
    1. they drove me crazy
    2. they had fallen off before, while I was wiping it off.
    Those were enough reasons for me.
    To answer your question, they are not necessary, but I do believe them to be an upgrade, and they don't hurt anything.
    p.s. I do NOT have them on any of my other rifles.

    I dont think they will hurt anything but unless you have a full auto lower I dont think they are really needed. Its your lower and if you want them go fo it.

    I would just leave them in since the lower came with them already installed. I've had two lowers with KNS pins, one was a dedicated 9mm lower and the other gets used with a .22lr conversion kit. I don't use the conversion kit very often anymore but I'll leave the pins in. They may not be necessary but I don't see the harm

    Used them for a year, because I bought into the "advantages", and standard pins do rotate. Plus, I have a JP fire control set and thought KNS pins helped the trigger pull. Recently changed to Geiselle pins, (which are .155" rather than mil spec .154"), due to concern that a primer may pop out, locking up trigger. KNS pins, even with 2 allen wrenches in the stock, are a pain to remove.
    No regrets going with Geiselle pins over KNS. Trigger pull still excellent.
    Read on ADCO's site that KNS pins use steel that is actually softer than mil spec, so while lower holes may not wear, pins might.

    I agree unconditionally but.... this issue is personal and subjective. How something looks can be argued like blondes/brunettes/redheads.

    How something "feels", like trigger pull, is also subjective unless we measure it.

    If the pins aren't as good as mil-spec with regards to service life and failure, then that's another matter that i would be interested in and someone in the forum may be able to help.

    Don't be a tool. After market whiz bangs and doodlebops add weight and change the manual of arms. Maybe less so in regards to these pins, but they will certainly change the ability of field repair. If something has no real purpose to enhance function or reliability than all you are doing is stroking your ego. Money would be better spent buying Jurgens lotion and stroking something that will put a smile on your face.

    I use them and have no problems with them. I went with them because I also run 9mm and .22lr uppers on my SBR lower which can be hard on standard pins. I have broken too many trigger pins to not use them.

    I keep a couple small allen wrenches in my grip along with an extra bolt, FP, and battery for my T-1 for field repairs
