Most Helpful Positive Review KNS is the best
KNS Pins are the best pins on the market. Installed them in every one of my AR rifles. The added brass tip and tools makes install super easy. In all of my friends and families rifles too! Gen 1 pins have cleared all of the after market accessories (extended mag release, and Phase 5 bcg release)
Most Helpful Negative Review Great anti-roll/anti-walk pin
Easy to instal, keeps the pins from wearing out the lower or walking out of the lower. So far so good, installed on each of my lowers as a must have, and haven't been proven wrong yet. Some say put on warn lowers, I say don't wear out the lower. Buy kns pins

my favorite anti-walk, anti-rotating hammer/trigger pins

by Concours14, Verified Owner from OH, United States Written on September 14, 2025
I have these KNS anti-walk/anti-rotating hammer/trigger pins on all my AR’s. I’ve tried other ones but found that other brands are not as well made or don’t work as well as these. They’re high quality, very well made products. They work exactly like advertised.
Pros:
  • Very we manufactured, easy to use, and at a great price point.
Cons:
  • None
Best Used for:
  • Target shooting & hunting
Would recommend: Yes

Well Made Kit

by Zippo, Verified Owner from NC, United States Written on May 13, 2025
I chose the standard size pins and used with a RRA 2-Stage trigger. No problems installing. Having a helper or a vise would help to hold rifle while turning both wrenches.

Best trigger pins

by Monster, Verified Owner from KS, United States Written on October 12, 2024
I use these in all of my builds. They are precision machined and polished stainless, so they improve the feel of all non-cassette style trigger systems by lessoning the friction of the pivot point for both the trigger and hammer. They are even better than the pins some "high end" triggers come with. The best, and worth every penny.
Pros:
  • The best pins
Cons:
  • None
Would recommend: Yes

KNS Precision Non-Rotate Trigger/Hammer pins

by Eliahurio, Verified Owner from MT, United States Written on April 17, 2024
I bought this for my Sig Sauer MPX because the trigger pin kept drifting out, causing a misfire during competition…not desirable! So far, these pins have performed exactly as advertised. Installation instructions made the install easy and flawless. Even better, the installation looks good and professional.
Pros:
  • Reasonable price, excellent quality, and a perfect fit.
Cons:
  • None
Would recommend: Yes

Great pins

by JT, Verified Owner from TN, United States Written on March 30, 2024
I have these on all of my AR’s and they’re the best pins I’ve used. Other brands I’ve used have corroded or stripped, but KNS pins have never given me any issues.

Easy Install & Quality

by Very Satisfied Customer, Verified Owner from CA, United States Written on February 18, 2024
After trying 2 other companies non-rotating pins, I’m very happy with these. The others I tried had wiggle to them & were difficult to install, these were super easy to install & are solid. Will use these on all of my builds.
