I bought a complete RRA lower this past weekend, and subsequently came across a deal on a new 7.62x39 upper that is just too good to pass up, i.e., free from a friend. Whereas my original plan was to build a 6.8spc on this lower at some point in the future, I'm toying with the idea of using the 7.62x39 upper in the interim. This will be my first "build", so can anyone tell me what I am in for? Should I expect the upper and lower to go together without any fuss? Is there a source for 7.62x39 AR mags that someone can point me to? Any advice will be greatly appreciated.
Thanks,
Pete
