This weapon can currently only be made through Aide Production. It requires the following:
Adept of Ages (19th Century) title or EX equipment with
Age effect (19th century) equipped to make the recipe visible.
Casting R13 (with or without boosts) for the player, as well as their reserve Aide in charge of recipes (note: R10+ is only possible if your aide has Casting +1 as their skill as this will give them +5 ranks to Casting; without +1 casting they cannot break past the R10 cap).
You must then have the following materials (either stored in appropriate the Quarters Storage tabs or in your Product Storage where Aide produced items go to be picked up at your leisure) as well, per rifle you intend to craft:
Pure Iron Sheet x5
