Thanks manPre-ban only matters in AR banned states, I'm not even sure it even matters in those states anymore. If you can find a state that allows you to have pre-bans with all of its evil features you could get about $1500 - $2k or so. Hell, I've seen pre-ban lowers go for $2k alone in banned stated.
Eagle Arms is a budget Armalite. So in none banned states, I've seen them go any where from $600 to $1000. However, they usually average about $800 - $900.
