So there is my bug / issue hope someone can awnser and clarify this.

You need to get equipped with all the important items regarding ammunition and for that, you need to know the codes No need to get worried, here we have the entire list of ammunition codes. I do not know if this is a bug or intended but then again if it is intended I dont get why Tinker Tom has theis special weapon mod that is the same as the mods I could pick up from any 10mm pistol since about lvl 10. Just like ammos, ammunition is equally important in Fallout 4. To spawn an item near your location, open the command console with the key and. The 'Deliverer Powerfull receiver' is the exact same as a regular powerfull receiver and it actually lowers my damage compared to the advanced receiver I have. This section contains the various Item Codes required to spawn Weapons, Armor, Meds, Chems and more in Fallout 4. I have an advanced receiver on it that came from my trusty 10mm pistol that I used since I picked it up in the Vault 111 at the start and had modified during my 100+ hours of gameplay. With the mod I walk to the craft table, click receiver scroll down and find out it is a basic powerfull receiver. I have allready modded my Deliverer but since it has this special name and Tinker Tom said it was to make my gun even stronger I figured I'll buy it. So I check his barter menu and find the 'Deliverer Powerfull Receiver' for x caps. I just talked to Tinker Tom and he told me he had some 'items' to make my Deliverer 10mm better.
