Again, forgive my ignorance, but what happens when I want to swap over and shoot Grendel out of that 6940? Wouldn't there be more choices on a conventional AR-15 platform? I see me buying a stock gun, mixing and matching components on it, starting with a Grendel upper and learning as I go, until eventually I have a stand alone Grendel build and the old original parts back on the original gun. By then I'm thinking I'm off to the races on the knowledge of the AR-15. While I don't question the value of the 6940, won't I be limiting my options on my swap outs as I go along? Are the lowers and recievers interchangeable?
