Simple esp replacer for Xilandro bow mod. just find the original B42Bows.esp file normally in your /steamlibrary/steamapps/common/fallout new vegas/Data delete the file B42Bows.esp from Data. then download this mod find the location where it downloaded to, open it add the B42Bows.esp from their to  fallout new vegas/Data and done no vortex needed just launch the game and get crafting.

why do this>  wanted a actual crafting system for the bow so I could use it in locations like dead money and others. The idea of scavenging resources from junk items and crafting weapon/s, ammo and other things was the only pleasing idea from fallout 4 so why not? Most crafting resources are made from common items (duct tape, clipboard, prewar money)and some uncommon (lead, 12g/20g hulls, adhesive) to give a better survival aspect.

the changes> umm the bows are both craftable i.e. you need one type of bow to craft the better one, most ammo recipes are eddied to be more efficient, the arrow/bow craftier cant be removed so no dropping or forced removal, most resources have weight and well go find out.

I highly recommend you go endorse Xilandro for all their actual hard work https://www.nexusmods.com/newvegas/mods/79786. 

A highly useful mode that fixes most crafting problems is https://www.nexusmods.com/newvegas/mods/59638 <recommendation not a requirement.
