Man arrested for selling 3D-printed machine gun conversion kits to undercover agents

Arrest for Illegal Device Sales

Emani Rey Justavino, 19, was arrested by Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) agents in Jacksonville, Florida. He sold "Glock switches," which are 3D-printed devices that convert semi-automatic firearms into fully automatic weapons, to undercover agents on two separate occasions. Possession of these devices is a federal offense, carrying a penalty of up to 10 years in prison.

Undercover Operation Details

The ATF initiated an investigation after learning that someone identified as "J.B.J." was selling these devices on Instagram. An undercover source contacted this individual and was redirected to "904hottshop," later identified as Justavino. Justavino sold four conversion devices for $200 on August 18 and later offered to sell 16 more for $400, or an entire batch of 50 for $300. He also offered a Glock 19 for $1,000, but the sale did not proceed.

Broader Concerns Over 3D-Printed Firearms

Authorities in states like California, Colorado, New York, and Washington are addressing the issue of 3D-printed ghost guns. There have been multiple arrests related to individuals using 3D printers to create conversion kits and complete weapons. This trend raises concerns about unregulated firearm production.

Debate on Regulation and 3D Printing

The increased focus on 3D-printed firearm components has led to debate. While authorities seek to control their proliferation, 3D-printing enthusiasts express concerns that overly restrictive regulations could hinder legitimate uses of 3D printing, negatively impacting education, open hardware, and small manufacturers. A federal judge previously struck down an ATF "ghost gun" rule, citing violations of the Fifth Amendment and the tradition of DIY gunsmithing.
