    Is there a downside to KNS pins?

    I just bought an M&P15 lower and it came with KNS pins installed. The guy gave me the OEM trigger pins as well.

    I'm just wondering if its worth my time to remove the KNS pins and install the OEM ones. These are the Gen2 Mod2 and with the reading I've done that says these are not prone to breaking.

    I've googled and searched but all I've found is that they are a waste of money and provide no benefit. Nothing that says they will have negative impacts on the weapon.

    no downside, just overkill,

    i do have a lower with worn pin holes that constantly let the trigger pin slip which lead to the disconnector not grabbing. Added the KNS pins and its all good now

    No, they are fine. If they're already on there then don't go through the trouble of taking them out.

    Alot of guys on here bash them because it is a $30 part that doesn't really add anything to the gun...but it doesn't take anything away either. I use them, but not for walking/rotating/grinding trigger/hammer pins. I use them as an index for my finger to make sure it is out of the trigger guard.

    Cons:

    They make dis-assembly a little challenging in the field.
    They will create little wear areas on the outside of the receiver.

    Pros:


    They won't walk out.
    They stabilize the pins by making the whole unit act as one.

    That works for me, thanks gents. I'll just keep the original pins as spares.

    No downside.

    If you yank them and put stock pins back in you will regret it (IMHO).

    Go ahead and do the switch.

    Don't take my or anyone else's advice. Do it as a learning experience.

    Check your trigger pull before and after.

    Report back with objective impressions and opinion.

    Out of the 4 sets I have wasted my money on... I'm pulling them from weapons one by one.
    Money is better spent on extra Colt pins and trigger/hammer springs.

    I bought them back in 06-07 when everyone was buying into the hype that they were needed; time has proven otherwise.

    *I have no idea the quality of S&W pins, the KNS may very well be stronger than their OEM. That said, I would toss the M&P garbage in the trash and get some Colt pins. Keep the KNS around as a backup (since there is zero resale value).

    Yeah the downside is having to deal with all the people who dislike the product. They may not be necessary but you already have them installed. I have a set and I think the trigger pull might even be noticeably better with my spikes NiB trigger parts, initially when I installed I forgot to grease the pins and they are not so difficult to remove or install but the fact that the securing screws are Allen heads sucks.

    LMAO

    I'm saving that for future use. I will give you full credit as the author of course.

    I had a DD lower at one time that had these installed when I bought it; I just left them in. I wouldn't actually pay for them and install them.
