Welcome to the forum. Like you, I built a 308AR as my first build. Everything I needed to know was found on this site, so just look around and keep reading. The folks here will help you spend your money, but they will also help you spend it wisely. Last fall I built my first 308AR and this season I put three whitetail bucks in the freezer with that rifle and the ammo that I hand loaded. It makes the meat taste really good! The down side is that I have now built 2 AR-15s and am looking at other calibers to add to the storage cabinet, wait, there is nothing down about that!
