Critique my 308 SASS build list

[Saluki2003]

Im going to be building a 308AR and would like some feedback on the parts I've chosen.  This gun will be for shooting at the range, hunting, and double as a battle rifle for SHTF scenario.  I want to build something along the lines of the DPMS SASS but I would rather put it together myself than buy a complete rifle.  I feel that this would give me the best understanding/knowledge of how my rifle operates.  Here's the list I've put together...feel free to rip it apart if there are parts on there that I should avoid and please suggest any replacements if there's some better value for any of these parts.
