Making good progress in my 2 AR builds, I only need a few things to get one finished. I am going to be using low profile gas blocks, but not sure what style. Clamp, or set screw? I think the clamp on style would be less of a hassle, but don't have any first hand knowledge. I just think the clamp on block would be less likely to work loose. Am I worried about the difference between 6 and half a dozen here or what?
