Deterrence Dispensed (DetDisp) is a decentralized, online collective that promotes and distributes designs for open-source 3D-printed firearms, gun parts, and handloaded cartridges.[1] The group describes itself as aligned with the freedom of speech and anti-copyright movements.[2]
DetDisp is best known for developing and releasing the FGC-9, a semi-automatic 3D-printed carbine requiring no regulated gun parts.[3] The group has been linked to the publication of the 3D files for the gun that killed UnitedHealth CEO Brian Thompson.[4]
History
editIn February 2019, a group of 3D gun designers chose the name "Deterrence Dispensed" as a reference to Defense Distributed, the first 3D firearms organization.[1] By 2020 the group claimed thousands of members, many of whom lived in jurisdictions where unlicensed firearm production was illegal.[3] Prominent among the group's pseudonymous members was the late German-Kurdish gun designer "JStark1809".[1][3]
Deterrence Dispensed has used multiple, alternative social networks and platforms due to suspensions from mainstream sites, including Tumblr and Keybase.[5][6] At one time, Deterrence Dispensed was the sixth most popular team on the Keybase platform, but by January 2021 they would be banned, a decision attributed to Keybase's acquisition by Zoom Video Communications.[5][7] The group has published files and blueprints on file-sharing websites built by LBRY, including the website Odysee, and has attempted to rebrand itself under the name "The Gatalog".[4][5]
In November 2024, the group's administrator Peter Celentano was arrested by the New York State Police and faces over 1,000 firearms-related charges.[4][8] In December of 2024, The Gatalog took credit for releasing the files for the printable frame and suppressor allegedly used by Luigi Mangione in the killing of UnitedHealthcare CEO Brian Thompson.[9][10]
Designs
editDeterrence Dispensed is best known for developing and releasing the FGC-9, a 3D-printed carbine requiring no regulated parts.[11] At the peak of its popularity, the group also distributed blueprints for AR-15s, an AKM receiver called the "Plastikov", handgun frames, and a magazine for Glock pistols named after New Jersey Senator Bob Menendez, who once pushed for crackdowns on the online sharing of 3D-printable firearms designs.[5][11] In 2019 the group released a design called the "Yankee Boogle", which is an auto sear that converts a semi-automatic AR-15 into a fully automatic one.[12]
Another Deterrence Dispensed design is FMDA 19.2, a Glock-derived partial 3D-printed pistol blueprint, released in 2021. In 2024, an iteration of FMDA 19.2 may have been used in the killing of Brian Thompson.[4]
Criticism
editSince the death of JStark, former members of DetDisp have been criticized for founding organizations in opposition to the original open source and anti-copyright values of the organization.[13]
