The KNS Precision AR-15 Hammer/Trigger Pin Assembly Guide (brand part no. KNSAR15THPGUIDE) is a small but useful armorer’s tool built to make removing and installing AR-15 and M16 trigger and hammer pins easier and cleaner. Pushing those pins in and out by hand or with an improvised punch risks marring the receiver finish or losing control of the pin mid-installation, and this guide is shaped specifically to prevent both problems. KNS Precision built the guide as a kit sized for standard AR-15 lower receivers, making it a sensible addition to any home armorer’s kit.
