actually not being specific on items, but depending on what you have toolwise you could easily spend another $150-200 on just tools. vise block, pin punches, wrenches for free float tube and/or castle nut, etc. going past that, first real choice and most important is barrels - length is pretty meaningful are sort of mutually exclusive. to really be a 1000 yard rifle, you'd want a 20" or potentially longer (nobody suggest 32" please :D ) but at the same time, if your primary objective is hunting, a 16" will be significantly lighter to lug around. the 308 ARs tend to be pretty heavy.
