The Rise of 3D-Printed Firearms: A Closer Look at the FGC-9

The Evolution of Homemade Firearms

Homemade weapons have a storied history that stretches back centuries, but the emergence of 3D-printed firearms over the last decade has fundamentally transformed the landscape of firearm acquisition and distribution globally. My colleague and I delved into the rise of a specific model, the FGC-9, which law enforcement officials have identified as the most prevalent 3D-printed gun worldwide. However, it’s important to recognize that this firearm represents just one of the many iterations within the expanding realm of 3D-printed weaponry.

How Difficult Is It to Fabricate a Gun?

While the process is becoming increasingly accessible, it still demands a considerable amount of technical knowledge. Those who are not well-versed in firearms or 3D printing might picture an advanced printer that can produce a complete firearm with a simple click of a button. In reality, the process is more complex.

Three-dimensional printing significantly lowers the barrier for the average individual to create a gun’s receiver or various components swiftly and at a relatively low cost. The receiver functions similarly to the frame of the firearm. However, other essential parts, such as the bolt, recoil spring, and barrel, are typically made of metal and are considerably more challenging to produce using a 3D printer.

Many websites offer metal barrels and bolts for sale, allowing individuals to purchase these critical components while printing the remaining parts themselves—almost akin to assembling a dangerous Lego set.
