Oh boy, so I am acquiring an m&p 15 Sport. Anyone upgraded one? Experiences? I am not a fan of the front sight gas block and will eventually change that, swap the hand guard for a free float and putting a low profile block or just chopping the oem block down to fit. Will swap the stock and pistola grip also for something that I feel looks and feels better. Not sure if I want to put a scope or red dot and buis yet. Anyway, anyone have one they'd like to share pictures of and input?
