Actually no. Starfleet has pretty strict limits on what you can replicate specifically to stop this kinda thing. It won’t let you replicate a material that pretty much only has use in explosives, for example.

I’m sure Cardassian replicators had the same shit, but their reasoning would be more fascist.

But if you got a Ferenghi replicator? You could replicate anything you wanted if you had the gold pressed latinum to pay for it. It might blow up in your face as it cuts corners and forgets a few molecules here and there to save energy (and thus money), tho.

My FGC-9 is still going strong after many mags and 3 years. I might make another soon since the 3d printed parts are probably getting worn by now, I’ll just have to price the parts from hardware stores.

The only parts from anything related to firearms is the AR trigger group, and that can be made at home with a lotnof file work and measuring.
