Optics are out of my price range for now, so these would be my primary sights. I'm trying to figure out where the prices match out too because if it's too expensive might as well bite the bullet on MBUS and just keep them on as back up sights when I eventually do get an optic installed. I found a top four list that recommend one sight from GGD for $44 but I the next entry on the list from colt is 4 times that price, and another offering from Aero is $80 so I don't know where they're squaring the difference in those prices. I've never heard of GGD but I know Aero and Colt probably did their homework on what a good carry handle needs to be. Should I just go with MBUS or are there decent budget options for A2 sights?
