Advantages of Nickel Boron:

Nickel Boron coatings are columnar in growth resulting in a distinct nodular topography which serves to reduce surface to surface contact of two mating / sliding surfaces reducing drag / friction. The nodular structure dissipates heat at greater efficiency due to greater surface area.

  • Harder surface results in less wear
  • Reduced Friction
  • Reduced Heat
  • Operates with little to no lubricant
  • Easy to Clean

Firing Pin (7.62x39):

There are two options for firing pins for this 7.62x39 bolt carrier group:

Standard: Same length as the mil-spec firing pin. Choose this if you plan to use USA made 7.62x39 ammunition only. Note: It is possible for the standard firing pin to not sucessfully ignite surplus/foreign made ammunition on the first strike due to the differrence in primers.

Enhanced: Firing pin pertrudes from the bolt slightly more than the standard firing pin. Choose this if you plan on shooting surplus/foreign made 7.62x39 ammunition only. Note: It is possible for the enhanced firing pin to puncture through USA made ammunition due to extended length. Heavy hammer spring may be required in addition to the enhanced firing pin depending on the type of ammunition.

We recommend that you purchase both firing pins so all types of ammunition can be fired through your rifle optimally.
