it was gonna be a nifbash of a harpoon gun but I'm not very good at learning things without guidance and there aren't really any guides for it plus i didn't really want to bother others for help so this is what you get but you know what that's ok.........
So it should have level listing spawning but i had alot of weapon mods on so idk if that works but if it does it should (if i did it correctly) Spawn on lv 35 gunners or higher i put a image of that escapade(all I'm saying Preston had more to worry about than the raiders.....) oh and what i had in visioned with a nifbash.
if you can't find it naturally (which I'm sure is a possibility) use in console: help M75TAW: and then use the id for it like this: player.additem (id here): then press enter and there you go OH and let me know if the gun is op or too weak but it shouldn't be either saying how rare 50 can be.....
Oh and if you are wondering about the name and what i had planned for a lore background here you go....... the full name is Model 2075 Tactical Assault Weapon
Being Designed in 2075 with production by the company's Manufacturing Dpt. starting in 2076 with it being a proposed to the U.S Army in 2077 as a Weapon that would be mounted to Armored Vehicle's and Aircraft and usable in a different configuration for Infantry but in that same year the U.S Army instead Adopts a newer model of Minigun and with Alot of the M75 T.A.W's Already being complete the Army paid and shipped All of them to Europe with only the spare parts left in a warehouse near Massachusetts and so when the Great war "ended" the warehouse was rediscovered in disarray with only the upper receivers Remaining the Discoverer's then use the leftovers to Create what you see before you.......
I did use a couple Guides at First for making custom Weapon mods but since it was custom models and blender is way to complex for me but i'm pretty sure you use it for nifbashing as well idk *shrugs but i will tell you what i did use here i go 1. the one by dak in which he made the frommer stop which is the one i got the most out of before i did my own thing 2. the one by the Rizzler in which he made the Hunting revolver and Ranger Sequoia it is very in depth. both are really decent(if your interested that sort of thing check em out) but you know when i said i got more out of daks as soon as he opened CK and explained it (i also made a discussion after at the time as well it also has some decent things in it) i decided to do this i made a couple things in it but this is the final product but i might try to remake the other things again idk but i will name them now:
