We’ve gotten calls and emails about these two firing pins being very similar in overall length, when the key difference in performance is the protrusion out the face of the bolt.
Mil-Spec firing pin protrusion is 0.028”-0.036”
Our 7.62x39 firing pin protrusion is 0.040”-0.050”
The additional firing pin protrusion aids with setting off steel cased ammo with berdan primers that may be harder, thicker, and set deeper than typical boxer primed brass ammo.
