I’m starting this thread as a build log for my first AR-15 build and my first AR platform rifle. I will come here from time to time to solicit advice from the membership about correct tools, parts selection, accessories, building techniques. This will be a budget build over several months. My rifle’s foundation will be this Ruger AR-556. I plan to build out the lower between now and the end of the year. Now to research lower parts kits, buffers, grips and triggers. This is a continuation of an earlier thread I posted regarding poly vs aluminum lowers.
