Know which diameter pin you need!
I had no clue whether .1555 or .154 was what I needed, so I bought .1555 pins. Wrong decision. They would not fit in a new high-end lower, not even close. I was able to put them into a Sig MPX and wow did it tighten up the trigger system. Also, high bolt speed on the MPX eats pedestrian trigger groups, so I was happy when they fit. I ordered .154 pins for the other and all is well. Quality, fit and finish are excellent, everything is good about the product. They are cheap and add life to your lowers.f
aluminum reciever why not?
I use KNS anti-rotation pins on every rifle build. AR platform rifles have an aluminum reciever and steel pins. Something is going to wear eventually. Why not minimize the potential for failure? Its inexpensive insurance against walking pins and oblong pin holes.
Pros:
- protect your investment. inexpensive.
Cons:
- None
Best Used for:
- all AR platform rifles (use the right diameter)
Would recommend: Yes
Use KNS on all my builds.
I’ve used KNS pins on all my builds. I always make sure I have a set of .155 and .154 pin sets on hand. I’ve found many lowers accept the .155 pins with no drama. Even quality parts from Aero and Noveske have varied between .154 and .155.
Would recommend: Yes
very tight fit
This is a very tight fit, but it really stiffens up the trigger. I'm not going to order this size anymore, but these are the best pins i've used. The difference in trigger feel is worth it alone. I can't believe that people rely on the standard designed pins.
Would recommend: Yes
Easy install
This was a very simple install. Only takes about 15 minutes to put in with the provided tools and a hammer and punch. Everything fit perfectly, no play in the pins or rattlels. I will definitely be buying again for the next build.
Would recommend: Yes
Works as advertised
This product works well and does what it should. While I don’t think these are necessary, I do view them as cheap insurance. It is nice that KNS includes both wrenches so you don’t have to hunt around for a spare. These install very easily in just a couple minutes (that’s taking my time). I would recommend these for anyone looking to protect their investment.
Would recommend: Yes
Best hammer trigger pins
I put these on all my ar15s, have broke hammer pins in the past, don’t have to worry about it with these. Also, the fde anti-rotation bar looks cool and is a good match. Not much else to say about them other then, if you want to add some dependability to your rifle, these are a must.
Would recommend: Yes
KNS Non-Rotate Trigger/Hammer Pins
When I purchased my first drop in trigger, I purchased these KNS pins and was quite happy with them. I later started a new build and decided to explore other brands of anti-roll pins and was not pleased at all. The locking face plate fell out of place and slowly did the pins. That ruined my day at the range and later that evening, I got onto Optics Planet and purchased 2 more KNS pins.
Pros:
- Works great and does what its supposed to
Cons:
- A little more expensive
Best Used for:
- Drop in Trigger
Would recommend: Yes

I have installed the KNS Pins on all of my AR's after having the trigger pin walk out on my during one of my range trips. Perfect solution to never having it happen again. Installation couldn't be any easier.
Pros:
- practical
- Very easy to install
- no more walking pins
Cons:
- Absolutely none
Best Used for:
- AR15/M16 platforms
Would recommend: Yes
Excellent Product
Easy Install everything went together perfectly. Used this with a RA-140 Trigger by putting in the KNS PINS and then releasing the set screws the trigger pull went from 4.5 to 4 lbs. happy with the product and took the weapon to the range and everything worked great.
Would recommend: Yes
