Did not you put a post about this configuration a while back? The key item that you have in you post is the collapsible stock. Do you want a collapsible stock or a NON-collapsible stock look-alike? Just remember, that the 1994 crime bill state you only can have two bad features. The pistol grip and using a detachable magazine are the usual two evil features that the government will allow you to have on a post semi-auto in a case of the current ARs. If you want the collapsible stock, you would have to get rid of the pistol grip or make the magazine permenment to the receiver.
