can a demilled gun fire again?

A demilled gun, which has been rendered inoperable through various means such as welding, cutting, or removing critical components, cannot fire again in its original form. However, if someone were to repair or replace the demilled parts, it might be possible to restore its functionality, though this would typically be illegal and highly regulated in many jurisdictions. The intent behind demilling is to ensure that firearms are permanently disabled and cannot be used again.
