I'm doing a little research (110% new to the whole rifle game so absolutely know nothing about everything) and my mind is made up about getting an EOTech red dot sight. I am just trying to figure out which one would be the best fit for my rifle. Its between the eotech EXPS3-2 and the EOTech XPS2-0. I want to make sure that it is above my A2 front sight.
