Seems he's looking for both, I'm suggesting nitride for both over phosphate. I like the stuff. Assuming nitrided bore, it's a big step up over phosphate. Good to know PSA never sells non-C158 bolts. They definitely do sell BCGs they don't specify as Toolcraft. In the top kit of the op, the bolt is specified as both C158 and then below as 9130....
