Made this a while back. Basically it expands the DC vendors to sell NV items like the GRA weapons, GRA weapon mods, magazines, a lot more ammo, reloading supplies, etc. Should save a lot of time waiting for vendors to restock.
Possible issue : Lydia in the tenpenny tower won't stock magazines, even though all other general store vendors do. FNV edit shows no conflicts though, so i can't figure out what might be causing it.
