TacFire Firing Pin Features The TacFire Firing Pin is machined from steel and finished in hard chrome a combination chosen for its wear resistance under the repeated impact cycling a firing pin experiences. At 3.95 inches in length the pin is sized to drop into AR15/M16 pattern bolt carrier groups chambered for .308 Win without additional fitting. The hard chrome finish also resists corrosion helping the pin function reliably even after extended storage or exposure to the elements. This makes it a dependable choice whether finishing a new build or restoring an older rifle to full function. Replacing a firing pin is one of the most common maintenance tasks on an AR platform rifle and having a quality steel replacement on hand keeps a build or armory ready to go. The chrome finish also makes the pin easy to inspect for wear since chips or flat spots show clearly against the bright finish. Builders completing a .308 AR platform project will find this firing pin a straightforward reliable component to include. It is equally useful as a spare part kept on hand for future maintenance needs.
