A guy at the store said you only really need to swap the barrel, I'm a noob so i don't know, it suprised me and didnt seem right. Is it better to get a whole upper? They did recommend .300 specific mags as it helps feeding.
You can take off the front furniture and bust out a barrel wrench, but a normal person would just swap uppers. But yes, he was correct: only difference is the barrel. Mags, bolt, carrier, etc are all interchangeable.
