Armaspec AR-15 Firing Pin Features The Armaspec AR-15 Firing Pin is machined from 17-4 stainless steel a material chosen for its strength and resistance to corrosion compared to standard carbon steel pins. The H900 hardening process increases the pin s surface hardness helping it withstand the repeated impact cycles that occur every time the rifle fires. This combination of material and heat treatment is intended to extend the service life of the part well beyond typical factory firing pins. The Silver finish reflects the natural stainless steel surface rather than an applied coating. Designed as a direct fit for AR-15 platform rifles the Armaspec Firing Pin installs using the same process as the factory component requiring no special tools or modifications. Replacing a worn or damaged firing pin with this upgraded stainless steel version helps maintain consistent reliable ignition across thousands of rounds. Builders assembling a bolt carrier group from individual components can use this pin as a durable foundation for their build. The Armaspec AR-15 Firing Pin is available for sale at GrabAGun for shooters who want a long-lasting corrosion-resistant replacement part.
