In the sister article to this one, I showed a video of Defense Distributed’s Ghost Gunner CNC mill that details finishing an 80% AR lower receiver.  As a counterpoint to the automated version, I’d like to show finishing off an 80% receiver using jigs from 80% Arms.

While a DIY approach to completing the machine work on a receiver won’t likely save you money (in the short term), it does have a number of benefits.  These include a more hands-on building experience and lack of serial number, among others.

Check out the below video from YouTuber nsz85 and compare it to the Ghost Gunner, then let me know which method you’re more interested in.
