Crush washer cupped-side goes toward the flash hider, cone-side goes toward the barrel?

Thanks.

Why does this matter?  Is it on the schematic or TM in a specific fashion?  Will the earth stop and begin to rotate in the other direction?  

NOTE
Recessed washer does not require torqueing
15B. Assemble compensator to the barrel using recessed washer (12991533)(fig C-6, item 5) with the large diameter of the recessed washer forward toward the compensator and the small diameter rearward toward the barrel. Tighten the compensator hand tight and then tighten a minimum of 90 degrees but no more than 460 degrees to
the center of the middle slot.

If you look in the ARMY 23&P this is how they state to put it on.

Sorry no picture but go to the download section and you can see this.
