can I put a mil spec upper on any old lower with any old barrel? ***see post 3 for clarification... through searching I do believe they are interchangeable
I was also wondering about the barrel length terminology. what is pistol length, carbine length, mid length, etc.? |

Quoted:
Try to be more specific in you questions, you will getter better responses. is mil spec and non mil spec interchangeable. could I in theory put a mil spec upper on a com spec lower, with a com spec barrel and a com spec bolt carrier... etc... interchangeable |
