I modeled this to practice using Fusion360, it is based off of HMG Cetme L bending jig. The mandrel is made from steel and the die is made from aluminum. You might even be able to 3d print, but do so at your own risk. You will also need 2 bolts, 8 washers, and 2 nuts to use the jig. Good luck and have fun with it.

All you need tool wise is a 100$ flux core welder…

If you're in the United States I would look for the nearest Harbor Freight to get a Hydraulic Press, you want the 20 ton press that goes on sale all the time (Especially for Black Friday.)
You need the hydraulic press to press the barrel into the front trunion. If you're going to 3d print a CETME Recei…
