I picked up a BCI professional on black Friday. I think I want to do this one with only Iron Sighs. I'm not against flip ups, but I will not be running optics, so they don't have to be. I think A.R.M.S. and GG&G look good but I was wandering if there was anything out there that you guys have used and been happy with. Since I'm not running optics, I'm looking at higher end sights.
