The KNS Precision Non-Rotating Pin Set (brand part number NRTHPGENJJBK) replaces an AR-15/M16 trigger group’s stock pins with a non-rotating design that stops pin walk and the frame peening it causes over time. Built in the Jesse James (Gen JJ) configuration at .154" diameter, the set uses stainless steel pins with black nitride-treated side plates that lock the pins in place so they can’t spin or walk out under recoil. It’s a simple, direct-fit upgrade for anyone running a duty or competition AR who wants tighter, more consistent trigger and hammer pin retention without machining the lower.
