Can you post a source? Not being argumentative, just that I find it nowhere! I'd also like to know how one snags a mil/LE upper.
The SIG 516 commercial ones are nitrided, but the mil/LE ones are indeed chrome lined (I have one).
Would like something definitive on the MCX uppers before I drop coin on one. If it isn't at least nitrided then I won't touch it. Prefer chrome lined though.
