Deterrence Dispensed

Deterrence Dispensed (DetDisp) is a decentralized, online collective that promotes and distributes designs for open-source 3D-printed firearms, gun parts, and handloaded cartridges. The group describes itself as aligned with the freedom of speech and anti-copyright movements.

DetDisp is best known for developing and releasing the FGC-9, a semi-automatic 3D-printed carbine requiring no regulated gun parts. The group has been linked to the publication of the 3D files for the gun that killed UnitedHealth CEO Brian Thompson.
