I live here in Wisconsin, where Bravo Company USA is located. Does anyone know if they make their own parts for their line of AR’s? By make, do they machine their own receivers, uppers, barrels, etc. I know Stag, S&W, obviously Colt make many if not all of the components that go into their carbines, but didn’t know if BCM does. I would drive by BCM, but don’t know what their address is. Thanks!
