Alright, I've been really curious about the BCMs for quite some time now. I don't have the money to throw out there to order a complete rifle but would the prices vary much by building a rifle piece by piece? I've been wanting to save for an optic but with the way its looking for gun control lately I'm pondering about just buying uppers/lowers whenever I have the cash to do so. I'm a poor recently HS graduate that ships for basic in november. What's are ya'lls opinions?
