Most Helpful Positive Review KNS pins for every AR
I use these pins on every build I do. Top quality product, and they come in all diameters you need for any AR. Very easy to install, each of the two screws are already coated in loctite. These pins very important to use if you use polymer lowers where trigger pins may loosen and back out over time. One pin is is slotted and one pin is screwed in place to prevent backing out and rotating of the pins both.

Save Your Lower Receiver

by Richard S, Verified Owner from CA, United States Written on October 28, 2025
I use KNS trigger pins on all my builds. Made in USA! You can see pins rotate and wear into your lower receiver when manipulating trigger. This stops pins from wearing into receiver. Highly recommend if you paid $$$ for that new lower receiver.
Pros:
  • Easy to install (be carefull)
Cons:
  • None
Would recommend: Yes

Pros:
  • dont ask just buy
Cons:
  • None

Top Tier Quality

by BigPapa, Verified Owner from GA, United States Written on June 27, 2024
I love these things. Honestly, why use standard trigger pins when this exists. I love the simplicity of design. It works so well I’ve put them on multiple rifles. If you like to shoot a lot and you like to shoot fast, this thing is peace of mind. Buy it. You wont regret it.
Pros:
  • well made
  • Intuitive
  • Matte finish
  • simple install
  • very human design
Cons:
  • None
Best Used for:
  • Keeping your trigger healthy and where it belongs
Would recommend: Yes

KNS Anti-rotate Pins

by Zap, Verified Owner from CO, United States Written on March 19, 2024
the trigger and hammer pins cannot walk or rotate when using a cassette style trigger so they work great. Depending on how much space there is on the lower receiver by the hammer pin hole, there may not be enough room for the pin bar to sit flush as the female end may be too big depending on design elements on the lower (careful when using billet). But, it will work with a milspec forged for sure.
Pros:
  • Simple & easy installation
Cons:
  • None
Best Used for:
  • anti-walk
  • anti-rotate
Would recommend: Yes
