The Wilson Combat NP3 5.56 BCG is one of the most important components used in Wilson's customs rifles. The bolt of this BCG is machined from 158 carpenters steel. This BCG is magnetic particle inspected and this assembly is high pressure batch tested. The NP3 coating makes cleaning a much faster process. Since Np3 lowers the coefficient of friction reliability can be increased.
