I have a brand new in box unfired Rock River BT3 enhanced AR-10. This beast has billet receivers, 16" precision fluted barrel with 1moa accuracy guarantee with reports of 1/2 moa consistantly, match 2 stage trigger, and 2 extra magpul 25 round window magazines. Can't beat this price except MAYBE some desperate online store. But factor in shipping, transfer, and tax, and you will never beat this price.
