3.3.1  Assembly is the reverse order of the disassembly steps. IMPORTANT: The firing pin spring, if it has been removed, must be assembled back onto the firing pin as illustrated with the spring all the way up over the retaining shoulder. (fig 10) Failure to do so can result in spring or firing pin breakage and failure to function. Upon reinserting the bolt into the upper receiver make sure that the last round bolt hold open actuator is positioned out of the path of the bolt.
