The instructor examines various components including the bolt, firing pin, extractor, and carrier key, performing critical measurements like headspace and firing pin protrusion. Key findings include poor staking of the carrier key fasteners (YFS fasteners), potential nickel boron coating on the firing pin, and a rough bolt face. The video also demonstrates testing the integrity of the YFS fasteners under torque and checking for gas leakage.
