Firing pin protrusion 110

I recently changed my bolt head and I wanted to check the firing pin protrusion. I should’ve checked it before I disassembled it. What is spec?

The factory setting usually runs .055", but it's better to make it .035-.045"

I think I was around .052 after the swap. Maybe I’ll back it off some. Thanks

1 tab's worth (4 tab lock) is ~.009. If your .052 now then 1/4 tirn will put you at about .043, right about where you want to be.
