Despite the recent extension of a temporary restraining order banning the distribution of 3D-printed gun blueprints online, the firm behind the blueprints has found a way to bypass the ban.

Defense Distributed is now offering flash drives containing the blueprints for sale to anyone who wants to buy them for the recommended purchase price of $10.

This move comes on the heels of a decision earlier this week from U.S. District Judge Robert Lasnik who ruled to extend an existing temporary restraining order against Defense Distributed, which prevented the sharing of online blueprints for the 3D printed guns.

According to Judge Lasnik’s order, “Promising to detect the undetectable while at the same time removing a significant regulatory hurdle to the proliferation of these weapons — both domestically and internationally — rings hollow and in no way ameliorates, much less avoids, the harms that are likely to befall the states if an injunction is not issued.”

The 3D-printed gun blueprints, which briefly became available online in July, spurred government officials to action in the days following their release, as background checks are not required for purchasing the blueprints and known criminals can easily access them.

Following a July ruling from the U.S. Justice Department declaring that the blueprints can be made available for download, Defense Distributed released the blueprints for nine different gun designs, days earlier than the previously announced release date of August 1.

As such, more than a dozen states filed suit seeking an emergency ban on the blueprints, which was originally granted by Judge Lasnick and was set to expire this week.

Offering blueprints for making guns such as the AR-15 rifle — a model used in recent mass shootings in the United States — available for purchase, Defense Distributed claims it has already received 400 orders for the flash drives so far.

The flash drives are only available for delivery in states that did not impose the ban.
