Good, Bad and Neutral. Firearms are not moral actors. They are not agents.
However, they are a means for bad actors to engage in evil acts and may push some agents towards bad acts. Meaning, in their absence, the morally bad actor would not engage in certain behaviors. In that aspect they are bad.
The same can be said for good.
