    Actually nothing you have said here is a compelling argument. Plenty of excuses though. You can do whatever you want. If you want to spend money on useless parts go for it. But I am not going to recommend or endorse them.

    Not everyone has the time to send parts in and wait for however long it takes. What if you need that rifle for a shoot or to go hunting this weekend, and need it to work.

    Like I said, its a quick fix for certain problems. If the world was perfect, we wouldn't even be having this conversation.

    You need to step down off your high horse , you think you have the right to determine who should own or be allowed to build or do what they want? The market clearly indicated that KNS pins have a use, as people are buying them, including people know know a little bit about building AR's. You can sink over $5K into building a gun with all the little do dads and features, but you are bitching about a $25, that will guarentee that your pins won't walk?

    Time and money are both resources. Maybe you should take a intro to economics. Not everyone has alot of either or both

    Guess if I was putting together an ar from unknown used parts that I got dirt cheap for a range toy and KNS pins could "fix it", I would get a set.

    Or if same situation with a complete ar, used and dirt cheap, I would get a set.

    I sure would not waste $30 to keep a set around, just in case.

    Only good for worn out guns now out of spec on the hammer/trigger/auto sear holes from oblonging, or new guns that where never in spec.

    I've seen a few M16A1 lowers that needed these -- any new gun that needed this I would send back.

    I bought an LMT two stage trigger, no J spring. Of course they made it good. No J spring. It's an LMT thang.

    The pins started walking on my old POF-415. I think the unique nature of piston rifle recoil can contribute to that. KNS pins fixed it - it worked in that particular application.

    You need to dial back your rhetoric and tone, if you want to stay here. Lose the attitude. Your continued bickering has been noticed by the mods/staff. Think before you ever post something like this again. The next time you talk like this to a mod or staff member, you're getting points towards a vacation. Consider this a public warning to match your public comments.

    I've never used any other pins beside the ones that were in the LPK.

    That being said, two of my trigger pins walk on new PSA lowers/LPK...I don't know if the lower is out of spec or if it's the pins included in the LPK.

    I think at the very least, I'm going to buy KNS replacement pins instead of the entire KNS anti rotation kit.

    I never had to use them before, but I figured $30 is inexpensive insurance since I know in my two lowers this is an issue.

    I think I'm now permanently jacked in with M4C. I literally woke up and the first random thought that popped in my head were if I should take my KNS pins off my Noveske lower, or if I should keep them and put them on my BCM lower too.
    Both of those lowers are registered SBR lowers so it might be cheap insurance. But then I thought 'what if I have a blown primer or some other debris finds its way under th e FCG and the only way to clear it is to remove the FCG...." Well that would suck.
    I don't shoot 9mm, I DO shoot a shit load of .22LR but haven't had any issues with pins breaking, I haven't had a blown primer, but I've seen several during matches I've shot at, mostly reloads but not always, I am starting to shoot my own reloads, I haven't experienced pin walking in any of my lowers, but one lower does have pin 'rotation' when I pull the trigger.

    So my analysis and conclusion tells me I am ditching them. That was weird.

    clicked in here b/c i just bought a set for a new 9mm. mine will never see the use that the range gun has (mainly 'cause i can't afford the ammo!), so hopefully my pins won't break and the holes will not get deformed.

    i think it's AMAZING that the carbine continued(s) to run with a broken pin. would that have happened with a non-KNS setup?

    (btw, OP, i would like to think you'd replace the pin before putting it back on the line. it's a firearm, and broke is broke).

    i think turretgunner's point, if not dialogue, was valid. once in awhile, these pins will patch a situation with out of spec parts.
    IG has the better solution, but it is still true that the cost/benefit of replacing a lower may be more trouble than it's worth. if $28 on the KNS kit + less time than it would take me to open a case with the lower manufacturer resolves the problem, why not?

    in any case, great OP and thanks for sharing.
