The Brownells 300 BLK AR-15 Build Showcase Part 1: Parts List

Well, it has begun!  Here at Desert Guardian, we are embarking on a complete AR-15 build with the help of Brownells.  This project will be documented start to finish here, as well as on our social media outlets.  Hopefully you will be inspired to build your own, and enjoy a fun learning experience from the milling of the lower, to the construction, to the range tests. Here where it all begins…the pile of parts!
