I went ahead and purchased bullet flight and am trying to figure it out, I'm trying to input data for my Noveske, and was wondering: what height should i put in for my BUIS (the troy industries ones that came with the upper.) i looked on their website and they just say that they are standard height. does that mean they are 1.5 inches high? also what height should i use for my EOTech 557 with no riser mount? should i use the same height?
