KNS Precision Hammer/Trigger Pin Assembly Guide Features The KNS Precision Hammer/Trigger Pin Assembly Guide is built specifically to solve one of the more frustrating parts of AR15 and M16 lower receiver work getting the hammer and trigger pins in and out cleanly. Without a guide pins can bind cock sideways or require excessive force that risks marring the receiver or damaging the pin itself. The guide holds everything in alignment so the pin travels straight through the hammer trigger and receiver holes on the first attempt. This is especially valuable when installing an aftermarket trigger group which often requires several rounds of removal and reinstallation to get spring tension and engagement correct. Supplied as a complete kit the tool is ready to use right out of the package without additional purchases. It is built for the AR15 and M16 platform specifically so it matches the pin diameters and hole spacing those receivers use. Gunsmiths who service multiple rifles benefit from having a dedicated guide on hand rather than relying on punches or improvised alignment methods that risk scratching the finish. For anyone doing regular trigger work or lower receiver builds the KNS Precision Hammer/Trigger Pin Assembly Guide is a worthwhile addition to the bench available for sale at GrabAGun.
