This is my first post on this forum, so please be gentle.
I decided to put together a light weight 16" 6.5 Grendel AR15 and purchased the following parts from Alexander Arms.

I've since gathered most of the remaining parts that I need including an Adams Arms piston system. I don't want to make any assumptions when it comes to this build. Is the barrel nut the same size as it would be for a regular 5.56x45 AR15 build? What's a good source for an inexpensive 9/16-24RH flash hider or muzzle brake? What's a good source for the crush washer?
