Changing mods and/or upgrades on a weapon will not increase the sale value. Anyone who is willing/able to pay that much for a weapon will also be willing to change it to suit their playstyle.
As mentioned in the Ventari's Corner PC stickies on rare weapons, the pricing is based on the weapon itself and does not consider mods/upgrades.
i didnt put i wasnt sure where to put it as the ventaris forum donst have anything about queries, like this is, i only throgut i might b able to make 10e more with a 20/20 and +30hp say ( example, dout u coudl make that much) as the buyer might not want to go and buy 20/20 + 30hp, cos al lthe weapons i see hae 20/20 + 30hp on them. ok thanx any way u can close this now
OP - Just so you know for the future, this was the correct forum to ask your question. Ventari's is for PC, sell or buy only and does not allow questions.
It's a nice hammer and all, but hammer's just don't get used very often... If I were you, i'd throw it up on the autions and like a 60k SB and a 100k reserve and bidding increments of like 5k...
You won't be able to make any money by adding mods because you'd only be able to add as much as the mods cost. People add 20/20 and +30 thinking it makes it more attractive to sell. It really doesn't because a lot of people don't use those mods (and 20/20 sucks but that's another topic) an would just change them anyway. So they wouldn't want to pay 20k or so more.
