But I was blown away when I saw the Pipe pistol schematics.

It appears that the lowly "pipe" gun will be able to be modded to possibly 10 different calibers and 30 distinct weapons.
That is amazing news in my opinion and should really put to rest the worries that FO 4 will short is on weapons.
This should greatly increase the variety of weapons we run across. I am truly impressed with the thought and detail that will be going into weapon crafting.
To paraphrase what was shown in the art we will have.
10 separate actions which i assume changes caliber.
6 pistol stocks, 5 lightweight collapsible stocks and 8 full stocks
12 barrels ranging from short to sniper length
11 magazines of varying size.
