Bolt assembly pin

You don't have to remove anything to set headspace.

True, but its a lot more fun if you tear the whole rifle apart first, and there's a certain, deep satisfaction of "knowing" it is done right, without taking any shortcuts.

Only if you "know" how to put it back together correctly.

I got a Shilen barrel Wed. and put it on a M10. Tried headspacing with the firing pin in, and the force required to cycle the bolt was excessive. I don't know how or why anyone would headspace a gun with the firing pin in the bolt. There's no "feel"!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Either the bolt closes or it doesn't, that is all that you need to feel when setting the headspace.

Hehe.

Nope you have to remove the brake and the butt pad first.
