https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1093538683&searchtext= This is literally the only mod on the workshop I could find that offers a vanilla weapon progression for craftable firearms with most mods ether only offering end game weapons (shellguard/knightfall) or implementing modern guns that are out of place in starbound. (feast of fire and smoke) Unfortunately the mod is defunct but it appears to be mostly complete and functional only missing a grenade launcher and rocket launcher set. If someone could pick this mod up and fix any bugs and add grenade launchers I would appreciate it.
