Deterrence Dispensed

Deterrence Dispensed is an online group that promotes and distributes open-source 3D printed firearms, gun parts, and handloaded cartridges. The group strongly supports freedom of speech applied to computer code and blueprints as well as the copyleft movement.
The group is best known for developing and releasing the FGC-9, a practical 3D-printed carbine requiring no regulated parts. Owing to the group's anonymous and decentralized nature, no specific legal challenges has been launched against DetDisp as of August 2020, despite being recognized as a threat by law enforcement agencies.
History.
Deterrence Dispensed is a loose group of 3D-printed gun advocates. An anonymous American who goes by the name "Ivan the Troll" has been described as a de facto leader of the group; a person who uses the name "J Stark" has also been described as a leader. In February 2019, the group chose the name "Deterrence Dispensed" as a reference to the 3D printed firearms group Defense Distributed. The group says it has thousands of members, many of whom are in jurisdictions that ban unlicensed firearm production.
Deterrence Dispensed has moved towards alternative social networks and platforms after being suspended from several mainstream networks. The group maintained an active presence on Twitter and YouTube until both platforms banned them in May 2019. The day after the YouTube ban, Deterrence Dispensed began sharing their videos on GunStreamer, a video sharing site dedicated to firearms topics. Reddit shuttered a subreddit focused around the group in July of the same year. Following the Reddit ban, Deterrence Dispensed migrated to Tumblr and Keybase, though Tumblr shut down their account the following month. In the two weeks after Deterrence Dispensed joined Keybase, they became the sixth most popular team on the platform; they would however eventually be kicked off from Keybase as well, in January 2021, a move which was attributed to policy changes after Keybase's acquisition by Zoom Video Communications. In 2019, the group also began sharing its blueprints on spee.ch, a now-defunct file-sharing website built by the LBRY team; the site was later replaced by LBRY.tv. The group has also used Signal, Discord, and Internet Relay Chat (IRC).
Designs.
Deterrence Dispensed is best known for developing and releasing the FGC-9, a 3D printed carbine requiring no regulated parts. The group also distributes blueprints for AR-15s, an AKM receiver called the "Plastikov", handgun frames, and a magazine for Glock pistols. The group named the Glock magazine design the "Menendez mag" after New Jersey Senator Bob Menendez, who has pushed for crackdowns on the online sharing of 3D printed firearms designs. In 2019 the group released a design for an auto sear, a part that converts a semi-automatic rifle into a fully automatic weapon. Called the "Yankee Boogle", the name is an apparent reference to the "boogaloo" meme embraced by the boogaloo movement and other firearms groups.
