Eric Gerard McGinnis learned his fate on Wednesday, the U.S. Attorney’s Office said. McGinnis was arrested in July 2017 outside of Dallas while he was test-firing the gun in a wooded area. Officers found him with a “hit list” of lawmakers he was thought to be planning to harm with the weapon, NPR reports.

The list was titled “9/11/2001 list of American Terrorists” and included bird Republican and Democratic members of Congress. The list also contained those individual’s home and office addresses.

In August of 2018, a federal judge made it illegal for people to post blueprints for 3D printed guns online.

While it’s not illegal to 3D print a gun, McGinnis had been under a protective order since 2015 due to a “violent altercation” with his girlfriend. At the time of his arrest, he was barred from owning a gun or ammunition. McGinnis had actually attempted to purchase a firearm in 2016 and was refused.

Rifle parts can be purchased by anyone without a background check. McGinnis had used a combination of purchased and 3D-printed parts to build a gun from scratch. He was able to acquire a barrel, stock, upper receiver, and grip despite the protective order. The only piece he needed to print was the gun’s firing mechanism.
