I need to disassemble the bolt of a Kimber of Oregon Model 84 (.223). There appears to be a tiny roll pin at the rear of the shroud, and the sear piece on bottom appears to have a tiny hex set. I'd greatly appreciate guidance on how to do this disassembly since I've never messed with one of these previously.

THANKS!

Anybody know how to tackle taking this bolt down?

That pin is actually the cocking cam,,,it's a LH thread

So do I need to remove either the cross pin at the rear of the bolt shroud, or the bottom screw, or both?
