Flat top body on M16A2
 

hey guys,
I would like to know if changing the upper reciever on an M16A2 to a M4 style with removable carry handle is as easy as swaping uppers. From what I have found the A1/VN would have other issues but the A2 should be just the reciever? am I right in thinking this or is there other parts I would need?

thanks for any info.

im pretty sure its the same. VN model not applicable.

I've seen alot of G&P M16's with M4 metal bodies.

thanks guys, thats what I thought I just wanted to confirm.
