For protecting a valuable select-fire receiver, or even a semi-auto receiver that has seen a high volume of fire, these non-rotating trigger and hammer pins are a must. Anti-creep retainers keep the pins from constantly rotating during extended firing sessions and weakening the receiver walls. Not compatible with Jewell match triggers.

Great part/great service


First, I don't think I have to tell anybody here about it however, The service from P.A. is the best! Second,The KNS trigger pin kit was a necessity for me as the trigger pin on my AR did walk and cause problems. After the trigger pin kit install the trigger felt great, like a million dollar gun. I make a you tube video about it here; https://www.youtube.com/watch?v=0M46ISI2SRII highly recommend it!

Great buy


Install was quick and simple, haven't been out th shoot since I installed the new pins but I have every confidence there will be no problems. Great service and fast shipping from Primary Arms.

KNS non rotating pins for ar-15


Absolutely great service and a great price. I purchased 2 kits for both my AR and my son's AR. I have purchased numerous products for our rifles from Primary Arms and very happy with both the excellent products and service!



Absolutely love these kns anti walk pins, most say they're for fully auto only, I disagree. Within a month of purchasing my rifle either being poor quality pins or me shooting the hell out of it my trigger pin began to walk out. I bought these and of course its not a problem now. Even if yours dont walk out this is like insurance and they give it a good look. Pretty simple install, just push your old pins out with the new ones.

Works Great!


Add a little lock-tight, and they'll never work themselves loose!!

KNS pins


After getting the wrong item in the right package(KNS's mistake, Jason promptly sent me the correct items along with a prepaid mailing label, great customer service. For the pins, I am very happy with the product,

Works as expected just a tad long


After installing the non-rotaing pins I found that the pins are just a touch longer than my lower is wide. Leaving a slight gap between for the pin interlocking parts and my lower.
