Got to looking at the box my RRA came in and noticed that it is marked " LE TACTICAL CAR RIFLE". Now I thought it was a Entry Tactical and that was what my dealer called it and the serial #'s match on the box so are they one in the same? The rifle I got has a heavy 16 inch tube, an A2 FH, a M4 cut in the barrel, and a flat top reciever. The stock is a six position M4 style and has a Houge pistol grip. Was it possible my lower was put on a different upper?

My Entry Tactical came the same way.  I was curious about that when I bought it too, but then I just went out and shot it.  Then my curiosity was replaced with this:    I didn't worry about it after that.  I guess if you really want to know, email RRA and ask.  Have fun with it.
