I know you need to purchase the items from GRA to actually get them, but where do you purchase them? Are they scattered in Vendors? Not in vendors at all? Do I have to find them? I downloaded GRA and I went to the Gun Runners and saw some new mods (I think they're new, I've never purchased actual weapons from vendors) Stuff like 9mm Ext Mags. and stuff. Did the download mess up? Or is it fully loaded and I'm only seeing a fraction of what they're selling.

The mods look new, like new mods for the flamer, but there aren't any new weapons in their weapons cache. Where do I find them?

there in every vendor fellow wanderer just got to look for them!

I assumed that, Bethesda being well, Bethesda, would drop the load all on the Gun Runners. It's refreshing to see them update ALL the vendors. But, I have a question. What if the Van Graff's were assigned the Bozar or whatever? I killed them, does that mean I can't buy it!?!?!? D:

umm..... yeah your going to have to find a different vendor for that weapon lol

Did the message pop up that says Gun Runner's Arsenal has been installed? Because obviously you have to wait for that until the guns appear.

If you kill the Van Graffs who have the energy weapons, then those will be put into the Gun Runners inventory. If you kill Cliff Briscoe, those guns will be put into the Gun RUnners inventory, and so on.
