The KNS Precision Gen 2 Non-Rotating Pin Kit in .154 diameter, Flat Dark Earth (brand part number NRTHP-154DE) replaces the standard trigger and hammer pins on a mil-spec AR-15 with a non-rotating design, which keeps the pin from spinning in place and wearing an oversized hole into the lower receiver over time. The stainless steel pins are paired with side plates finished in black nitride, and the whole kit is finished in Flat Dark Earth to stand out from a typical black build or match a Dark Earth furniture set. It drops straight into any mil-spec AR-15 lower.
