Have you ever wondered how to make an AR-15 complete lower out of an 80% lower? Well, 80% Arms does a damn good job of showing you how while using one of their jigs. We’ve built lowers this way as well as with other jigs but we found it easiest using the Easy Jig from 80% Arms. Check them out if you’re interesting in this type of AR-15 lower receiver build!
Once you’ve completed your build make sure to check out our lower parts kits!
