Building Your Own AR-15: The Essentials

A Beginners Guide to Starting an AR-15 Build

Whether you have built your own AR-15 before or you’re looking at your first build, it is important to know the basic must-haves you will need for your build. A barebones list of the basics to get you started on your build without the additional fluff and nonessentials.

Using Google will go a long way in helping you figure out how to build your weapon, but most other lists will always come up with a bunch of stuff that you don’t really need for your build. So we have compiled a short list of essentials that will get your build started and completed easily without having to drop extra money on a whole slew of junk bogging you down.
