how come everybody goes flat-top these days for optics? does the front sight not get in the way? http://www.del-ton.com/B_Square_AR_15_Mount_p/mt1008.htm I used to see these kinds of things in pictures a lot.. and now I see the RRA tactical mounts, which seemed logical to me.. but nowadays everybody keeps saying go flat-top. How do you guys deal w/ the front sight on an ar? do you just buy higher scope rings or something? What if you want to buy an ACOG, which seems to have low mounts? same for EOTech.. doesn't the front sight get in the way of the reflex picture?
