Alright so I'm building a couple budget ARs for two family members. All I need now are some rear "irons". For budget reasons I am considering the Magpul Polymer BUS or the A.R.M.S. #71 Polymer, rear sights only. They are light barreled carbines and will only see light duty range use. I am a steel and wood kinda guy but they wouldn't know the difference. What say the Hide? Are they any good? Other brands or good price point sights available?
