Roberta X looks at the progress of Homemade Fabs and small scale MFG.
For example the upper and receiver for my AR 45 were built in small shop the latter being custom CNC'd.
People being able to build their own parts as they needed is very freeing for do it yourself work and self determination.
It also shows the futility of gun control. What'll the gun grabbers do if the base metal parts can just be printed up? Ban springs?
An ammunition ban only goes so far.
