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!

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.

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).



They fit good and will keep pins from moving out

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.

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.
