How much grease should be on my firing pin?

[Ridge Runner 0]

I recently disassemble my JAR and discovered that my firing pin is caked with grease.

Is this a good thing. Should the inside of the bolt be loaded with grease or oil?

Ridge Runner, the firing pin should be lightly oiled and no grease. Grease will cake up and eventually impede the travel of the firing pin. The firing pin spring has the job to prevent slam fires and also retracts the pin below the face surface of the bolt. If this firing pin is held extended out past the bolt face from dirt or caked grease, you stand the chance of having a premature primer strike setting off the round before the bolt is in the battery position. Cordially, Alasdair
