It hit me a couple of days ago that before a jillion uninstalls and reinstalls I did on FONV, I used to play with a short quest mod that led me to the base of some legendary mercenary that had completely modable weapons. And I don't mean ''slap 3 attachments to it'' kind of modable.
There was an assault rifle (I think it's a 55x SiG variation...might be 551 or 553, can't remember really), you could switch between 5 mods on, as well as the ammunition type it shoots. It could be both 5.56 and .308.
The mod had another 3 weapons, an SMG (UMP45 - 9mm and 10mm hot switch), a shotgun(12 and 20g) and a Desert Eagle (.44 and I think .357).
I'm pretty sure I found the mod on Nexus, but they most likely deleted or hid it for copyright or whatever. It was a ridiculously good weapon mod but I can't remember the name of it, so could anyone please help me and point me in the right direction? Thanks in advance
