Motor City Armament is essentially a small machine shop in an industrial area of Detroit city primarily manufacturing AR15 lower receivers and tactical knives. However we have recently developed a new upper receiver/handguard rail system for the AR15 which we would like to debut at Shot Show Extra 2022. In the future we plan to dedicate the machine shop entirely to the manufacturing of these upper receivers. The website is currently being restructured to only display and sell these upper receiver products and will be up by Jan 1st. (less)
