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 an integrated crush washer, while others do not. If the flash hider doesn’t have an integrated crush washer, then you’ll need to buy one separately. Always check the manufacturer’s instructions to make sure you’re installing the crush washer correctly. Incorrect installation can damage the flash hider and void the warranty.
