Precision machined stripped Ar15 bolt, with DLC Diamond Like Carbon coating. The DLC has good hardness, durability, and low friction. Always a good idea to have a few spare bolts. At this price, it’s a no brainer.
9310 Steel, when properly treated, is stronger than c158. These are properly treated.
