I am putting together a new barrel on my AR15 with an A2 birdcage. Anyone know which way to install the crush washer and what foot pounds do I torque it to?

Looks like below. The crush isn't set by poundage that I am aware of, it is used to time the brake.. so you have the openings on the birdcage lined up where you want them...

15-20 foot pounds according to the USMC Armorer's manual. The crush was goes on with the cone pointing toward the receiver. If that's not clear, I'll post you a pic.
