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.

These pins have been engineered specifically for use with the Smith & Wesson M&P15-22.

Now available with Flat Dark Earth cerakote finish!

Nice Quality


I used these on all of my ARs. Great quality, easy install, and they look good (which is saying a lot for pins).

M&P 15-22 parts


I was having trouble finding non-rotating pins for a M&P 15-22, as normal AR-15 pins are too short. The people at Primary Arms had exactly what I needed and the parts arrived quickly and in excellent condition. The pin set fits like a glove and looks great. Excellent company with great staff.

KNS Pins for S&W M&P 15-22


Pins are just a tad bit longer to accommodate the slightly wider (read out of spec) M&P 15-22 lower receiver. These provide a perfect fit and function. KNS makes fine products you can trust. I have these non-rotating trigger/hammer pins on every AR I own and used them on my M-4/M-16 in the Army.

Incorrect Pins


Received my pins the other day only to find that they were the incorrect ones ordered. Contacted Primary Arms who immediately corrected the error, provided a postage paid mail document and they arranged for the correct pins to be shipped directly from KNS within 3 days. Thanks to Scott and Brett from Primary Arms and to Gordon from KNS. Very impressed with the follow-up service in regards to my order.



They fit good and will keep pins from moving out
