Hard Chrome Firing Pin (5.56/.223/300BLK)

In stock

Hard chrome coated stainless steel firing pin optimized for .223 and or 5.56 parent cases. It'll also work great with soft-primed commercial 7.62x39 ammo, it is not suitable for harder milsurp primers.

Note that this is the original M16 version of the firing pin which means the retaining disc is 0.370" wide. So it may not fit in AR-15 unshrouded Bolt Carriers. You can read more about this distinction here.
