JE Machine Tech AR-15 Anti-Walk Pin Set Features The Je Machine Tech Anti-Walk Pin Set addresses a commonly overlooked weak point on AR-15 pattern rifles and pistols the trigger and hammer pins that hold the fire control group in place. During sustained fire sessions or simply over time factory pins tend to rotate and walk out of position which can lead to premature wear or even failure of critical fire control components. This set is designed specifically to prevent that walking motion keeping the hammer and trigger pins seated correctly through extended use. Built from steel and finished in black the pins match the durability and appearance of most factory AR-15 hardware. Compatibility with OEM spec fire control groups and lower receivers means the set drops into most standard AR-15 builds without modification to the receiver or trigger group. Installation hardware ships with the set giving builders everything needed to complete the upgrade in one package. At just 0.04 pounds the pin set adds no meaningful weight to the firearm while addressing a real reliability concern. The Je Machine Tech Anti-Walk Pin Set is available for sale at GrabAGun for AR-15 owners who want to protect their fire control group from premature failure.
