I am looking at getting a 308 ar platform rifle and I am new to this, but was wondering if I can interchange uppers on the rifle...for example can I use a DPMS 308 lower and put on a 338 federal upper on it? will they interchange with a Rock River 308 lower? I want a reliable, light 308 AR platform that can have the option to change uppers in different calibers.
Will DPMS uppers fit on a rock river 308 lower?
thanks,
John
