Looking for more stores with mods .. anyone got A list.

I know of the gun runners and the silver place in (freeside) and working on BoS HV

i think its a little bit random, i'm not sure but i think any vendor can have a mod

the ones i know of for sure tho are in goodsprings, trading post 188, novac and the mojave outpost

Silver Rush has energy weapon mods.

Has anyone been having a problem with merchants not refilling their wares? Some of the ones in my game don't seem to.

You have to take note that the Silver Rush focuses on Energy Weapons, while the Gun Runners have more ballistic weapons (Guns skill based).

I would like to know as well. I got mods for the varmit rifle and thats it. All other mods I kept finding didnt apply to the weapons I had better luck with but boy did the night vision scope and the extended mag on the varmit rifle made it a great mutated animal killer but the small round just wasnt that good even as armor piercing.

basically any weapon vendors can have random mods chet in goodsprings the guy in the dino and others also travelling merchants sometimes have mods but what mods are totally random if they don't have one you want then wait for them to restock (which like F3 takes Time)

there is a gun runner under the overpass at the 188 Trading post... i got a Sniper Rifle there along with a Mod for my Assault rifle, and my new Sniper Rifle... SUPER EXPENSIVE THO!!!!!!!!

I find a lot of mods at Gun Runners, they change stock every few game days too so just check back with them every so often and you can get a decent selection. I think random caravans wandering the wastes also have weapon mods sometimes, but those are really hit and miss usually.
