I'm new to the world of ARs and have a question. Can any upper go one any lower, example I just bought a RRA with a 24inch flat top upper could I buy a 16inch upper of a different brand and put it on there with out gun smithing?
Also if I decide to get a new upper can it be shipped to my house or does it have to go to a dealer?
