Armaspec AR10 Firing Pin Features The Armaspec Firing Pin is machined from 17-4 stainless steel a precipitation-hardening alloy chosen for its strength and resistance to the repeated impact a firing pin experiences with every cycle of the action. Once machined the pin undergoes H900 hardening a heat treatment process that brings the steel to a hardness level suited for the demands of striking a primer thousands of times without deforming or chipping. This combination of material and treatment is intended to improve reliability over a factory firing pin particularly in rifles that see heavy round counts. A properly hardened firing pin reduces the chance of light strikes which can cause failures to fire in an otherwise correctly functioning rifle. Built specifically to fit AR-10 pattern rifles this firing pin is a straightforward drop-in replacement for shooters maintaining or upgrading their rifle s bolt carrier group. The silver stainless finish matches the appearance of most factory and aftermarket bolt carrier group components keeping the look of the action consistent after installation. Replacing a firing pin is one of the simpler maintenance tasks on an AR-10 platform making this a practical part for shooters who want to stay ahead of wear rather than waiting for a failure in the field. For anyone running an AR-10 hard the Armaspec Firing Pin offers a durable properly treated replacement part.
