Printable Frames and Receivers
These projects generally use a 3D-printed frame or receiver, which is combined with firearm parts to create a finished firearm. Some of these designs can fire over 1,000 rounds without the frame or receiver failing. Projects in this category include a variety of AR-15 lower receivers, such as the UBAR2 and the Hoffman Tactical SL-15, a vast array of Glock frames, like the FMDA DD19.2, Ruger 10-22 receivers, and a variety of MAC11/9 lower receivers. There are also projects based on Smith & Wesson M&P pistols, Ruger pistols, Beretta pistols, CETME rifles, the Kalashnikov (“AK-47”), and much, much more.
