I would start with an adjustable gas block.
Just curious... Is there a maximum magazine capacity for hunting big game in Washington? Not that you would ever need it, but can you hunt with a 30 round magazine? 10 round magazine? I've never known the answer and have been told multiple things. My AR is chambered in .223 so obviously I'm not hunting big game with it, but I've always wanted to know the correct answer. Thanks.
