The Feinstein AK Mag is a 3D printed magazine for the AK-47 rifle. It was created by Defense Distributed and made public on March 2013. The magazine was created using a Stratasys Dimension SST 3-D printer via the fused deposition modeling (FDM) method.
It is a 30-round 7.62×39 AK-47 magazine. It is named after the anti-gun congresswoman Dianne Feinstein. Cody Wilson (founder of Defense Distributed), said the magazine’s name is a symbol of what’s happening in congress and reflects Defense Distributed's belief the proposed ban on assault weapons by Dianne Feinstein will fail. The original prototype was able to withstand 60 rounds before it began to crack.
