Was looking at the different ASIs, from the Horus Vision which seems hit and miss on the site, to the Flatline OPS or the Defensive Edge one. But before getting to that part, I have to ask what part a canted base will play in rendering the ASI inaccurate? I don't know the math to figure it out, hence I am asking those that know more than me. Looking at it for a .22LR that will get a 25-50 MOA base for the Best of the West range. I know it might not be that useful, but I think that it's help in learning what's going on in the mechanics will make it worthwhile.
