Just curious. I saw where Grumpy was going to have it done but didn't hear whether it actually was or not. Also saw where Jayson from IGF was looking into offering it.
Reason I ask is that there is a lot of conflicting info out there on the different surface treatments, namely one form or another of nitriding. The MR556 barrels (like most firearms) are test-fired at the factory. Since surface conversions are *supposed* to be done on, shall we say, "virgin" steel, some have said that it wouldn't be 100% successful if done on an already-fired bore. Also, the finish is supposed to be rather rough inside the bore after treatment resulting in the need for some kind of lapping or polishing (?).
