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.
