These guns are not mil-spec they're what they call it commercial spec gun. An upper will fit any lower but it's just not quite the same if you know what I mean ... The takedown models about anything you really want to do with them they have to be sent back to the factory

So, JEBh36........
Are these guns Mil spec?!?!?
What have you done?
David Knutson claims they are commercial.
Any more advise here?!????
