(Continued from Part 2.)
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.
For many builders, the biggest challenge in a project using a lot of firearm parts is the sourcing of those parts, especially if it’s for a firearm that’s out of production. The media may rant about the availability of “parts kits” or “builder’s kits,” but the truth is that for many firearm projects, the builder must order each part needed and may have trouble finding some parts.Continue reading“3D-Printed Gun Components – Part 3 by M.B.”
