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.
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.
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.
If this doesn’t qualify as the most ignorant post that I have ever read here.
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:sarcastic:
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.
they drove me crazy
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
