KNS Precision Non-Rotating Trigger/Hammer Pin Kit Gen2 Mod2 Features The KNS Precision Non-Rotating Pin Kit replaces the standard trigger and hammer pins in a mil-spec AR-15 or M16 lower receiver with stainless steel pins designed to stay fixed rather than rotate during firing. Over time standard rotating pins can wear and enlarge the pin holes in a receiver and the non-rotating design addresses this by locking the pins in place with duracoated sideplates. The .154 diameter pins fit mil-spec AR-15 and M16 lowers without requiring any modification to the receiver itself. This Gen2 Mod2 version represents a refinement of KNS Precision s original non-rotating pin concept for improved long-term durability. The sideplates are duracoated in red giving the kit a distinctive look while adding a layer of surface protection to the components. Because the pins are built from stainless steel they resist corrosion and wear better than standard mil-spec pins over years of use. This kit is a simple upgrade for shooters who want to protect their receiver s pin holes from the wear associated with standard rotating pins particularly on rifles that see heavy round counts. For AR-15 and M16 owners looking to extend the service life of their lower receiver the KNS Precision Non-Rotating Pin Kit is available for sale at GrabAGun.
