Hehe
Edit, 1st picture is a stock TM M16A2 with upgraded internals, second picture has a one piece outer barrel and a G&G reciever, 3rd picture is pretty much the same stuff but with an M203, 4th I took the m203 off and made a little grip, 5th picture I added a scope.
Note: The last picture is not how it currently looks, as I'm too lazy to take pictures.
