Fin added a new file:
QuoteThis mod allows the creation of custom weapons via json files. These weapons can then be crafted in the hideout, and several very silly guns are included by default, including a PPSH with AR-15 handguard options, an MP7 pretending to be an M14 EBR, and the F2000.
Also contains an option, disabled by default, that makes all mod parts compatible with all weapons, to aid in the creation of your weird guns.
Check the readme for more details.
