How to Build an AR-15 Lower Receiver
Building a standard AR-15 Lower Receiver is pretty straightforward. Watch as Larry Potterfield, Founder and CEO of MidwayUSA shows how it’s done. Starting with an explanation of the tools required, from the lower receiver action block to all the taps and drill bits, the use of each tool is explained in detail. The build begins with an inspection of the lower receiver, followed by the installation of the trigger guard. Next, the magazine release, bolt stop and detent pins are installed, followed by the hammer, trigger and safety. The buffer tube assembly and buttstock complete the build of the lower receiver.
