Weaponsmith Archive

i know there are other types of items that you may use ina gun but hereare my questions...

can you mix and match i mean can all you parts be made out of special peices like that so as to have a very high quality gun? or not?

what makes the best for each catagory?

are there any special weapons that can be crafted from a quest such as the RIS in an armor?

is there any that can looted from npcs?

if so what are the best things you have seen in each catagory?
