| I have looked several times and have not found an answer. Does anyone have a guide for manufacturing marks to tell who made an upper receiver? Some have an "A" looking symbol or a keyhole looking symbol. Thanks in advance. |

Here's the forge list. Unfortunately it only tells you who produced the raw forge, not who machined it. Given multiple companies use the same forge, its impossible to tell who made which one. You can only be confident that certain companies are known for using certain forges. |
