It seems like most Replica Airguns collectors are looking for their Replica Airguns to be made out of metal. I even get people complaining about the frames of their airguns being made out plastic (polymer), when in fact the real steel version the gun is designed to replicate also has a plastic or polymer frame.

Of course they use high grade hardened steel in areas where the gun receives the most pressure and continuous wear and tear.
