KNS Non-Rotating Trigger/Hammer pins:

Designed to prevent rotation of trigger and hammer pins which supposedly wear the aluminum receiver pin holes over time, causing them to widen or wallow out.

Anybody use them?

I am no expert on AR's but seeing plenty of beat up M16's and M4's with many rounds shot They seem to keep great groups their entire life, i feel these pins are overrated and pretty silly myself.

But like I said Im not AR junky.

I think they are silly too. I can't ever see the normal pins falling out.

I didn't think they would have that much of a following. If they were really necessary, I'm sure LMT and COLT would install them from the factory. Though I'm not really convinced that anything bad will happen from not using them, I saw a lot of pictures of AR rifles with them installed over at ARFCOM which got me curious about what the heck they were and why.

I think they're ugly.

I have them on all of my ARs. They're not that expensive, and they give a little extra peace of mind.

+ I have them on 1 lower and have ordered another set for my LMT

Spend the money on ammo instead.

I thought these are mostly to keep the pins from rotating when pulling the trigger hence the name "anti rotating" pins.

They aren't called anti fallout pins.

I haven't used them but I may pick them up for my long range build.

I usually see them when people buy the drop in trigger kits. These need the anti-rotation pins, but use them to hold the drop in trigger kits in place, not for the anti-rotation function.

Everything I've seen says these are really only needed when there is a lot of FA fire. Don't know how valid it is, but all the FA ARs at my local range haven them, and none of the SA do. But who knows.

So what I'm gathering from everyone is pretty much how I felt about them. Not necessary, but can't hurt to have in the longrun. I'd like to preserve my lower for as long as possible, so if I find a good deal on these at some point I might pick them up. Certainly not in a hurry, though.

I bought a (gen 2) set to try out on one of my lowers. It works as described, but also increased the trigger pull weight. I don't really like them too much honestly.

I also have a couple sets of anti-walk pins and like them a lot better. And they're less expensive too. DPMS and JP Enterprises both make similiar ones, but the DPMS costs about a 1/3rd of what the JP does.

With the anti-walk, I feel does make the rifle more reliable because if the trigger or hammer pin tries to back out even a little, it'll lock up the trigger assembly preventing being able to shoot. Don't ask me how I know .

It doesn't happen often, but the antiwalks are definately something I wanted to use and I do feel they're more useful than the KNS.

My 2 cents.

Miltary rifles have more rounds down range and are abused way more then 99.9% of any civillians rifle every could be.

The military dosent use them, not even SF. I've seen some pretty beat up rifles (especially by the Marines) and they continue to save and take lives with great accuracy and dependablity.

Spend the money on more ammo.
