Hello!
Are crush washer necessary for flash hiders? Why is there a crush washer on every AR? Is just to line up the Flash hider/Muzzle brake? Or does it serve a special purpose?

It depends on the flash hider. Some have a built-in crush washer, while others do not. If your flash hider doesn’t have a built-in crush washer, you will need to purchase one separately. Be sure to consult the manufacturer’s instructions to ensure that you are installing the crush washer correctly. Improper installation can damage the flash hider and void the warranty.
