Okay, all the time I see people on here talking about having Uppers in different calibers for their EBR's.
So, does a different Upper just let you shoot a different caliber with the same lower half? If so, are they sold as guns themselves? And, do you have to buy different magazine for all the diffrent calibers?
Finally, do they only work with a certain brand? I mean do I have to buy an actual Armalite AR-15, or can I buy a cheaper Bushmaster, and still swap out the Uppers?
I am only an egg, trying to grok.
