I'm just about finished with my OLL build for here in Kalif. Now I need to start thinking about the upper that best suits my needs. This rifle will be used for hunting ground squirrels and rock chucks out here in the West, so a scope is primary. However, I am not blind to the needs of a SHTF/post Katrina culture where open sight are needed. Can you folks offer some suggestions about how I should go? As usual, money is a consideration around here. God bless...
