My supplier, surplus ammo, has started coating their carriers with NiB. They didn't raise the price on them, so since I am starting my next build, I went ahead and ordered one for it. I should have a range report in a few weeks to give the group. I haven't had any problems with their parts, so I don't anticipate any with this one. I was kinda leery at first because of the results of the BCG hot potato thread a while back with Fail Zero, but I will give these folks the benefit of the doubt.
