However, it was not illegal to have some of the internal parts that let you make a machine gun as long as you didn’t actually assemble the machine gun. Under Federal law, it was and still is illegal to have an unregistered machine gun. But, Americans being Americans, we hate the idea of paying a tax for a constitutional right. Thanks to inflation, what was once a prohibitive $200 tax on machine guns was now more easily in reach for many people. The fairy tale of gun freedom was over, and most Americans forgot about these kinds of weapons that they couldn’t afford anyway.įast forward to the late 1970s. But then the government got involved and decided they were too dangerous, effectively banning them by way of heavy taxes and selective registration schemes under the National Firearms Act of 1934. Many fairy tales begin with “once upon a time,” and once upon a time in the United States, anyone could freely own a machine gun. Let’s take a closer look at the strange and sometimes weird history and reality of the DIAS. If they are legal, what made them illegal? And are there ways to legally acquire and use one? There are conflicting circuit court rulings, Federal law, and ATF policies that have all influenced the status of these parts. However, there still remains a lot of confusion around drop in auto sears. That didn’t stop a vigorous trade in them that lasted for more than 30 years until the ATF put a stop to the sale of them. In the eyes of the government, there is no reason to own a DIAS unless you intend to use it, and using it is quite illegal in most cases. For a long time they were openly sold and marketed to consumers with the implication they were perfectly legal to own as long as you didn’t actually use it. Drop in auto sears (DIAS) are a near-mythical part for AR-15s that, when used with certain other parts, can convert them to full-auto fire.
