How to Build an AR
If you want to build an AR, you need the right components, the right tools, and the knowledge to build it right. We will cover all of these elements in this series of instructions. We include instructions for all three AR classes, including the AR-15 (small frame AR), AR-10 (large frame AR), and AR-9 (pistol caliber AR). While we prefer to build on the Aero Precision Enhanced platforms, we also include instructions for the standard AR platform.
