Here PXSupply has those way cheaper, just ordered mine got it within less than a a week. They are real MSA, but not issued to troops. The build quality is great, it's nice and sturdy. All I had to do was go the local home depot to get some screws nuts and washers. I've got the foliage green one on my Pro-Tec helmet, fits great. Real solid for cycling.
e/ actually these aren't made by MSA at all, my mistake. For some reason I thought they were. But they ARE both the same chin straps, so there you go save some money
