Go-to stock without question - B5 Systems Bravo Mil-Spec AR Collapsible Buttstock

B5 has the stock game down!, I have one of these stocks on multiple builds, this is the tightest stock on the market(it "hugs" the buffer tube very well). The cheek weld is perfect for a scoped setup, and the black multi-cam option will make your rifle look "professional", not "cheap". For less than $100 total, this stock has all the options you will need and with the overmolded feel, it will last forever. I know building multiple AR-15's from the ground up can get expensive when you add all the little parts up, but the B5 Bravo Stock should be your go-to stock without question.
