We can accessorize these AR-10 or 15 platforms to any specification you might require. Call me and discuss your plans. We will ship to these FFLs anywhere that they are not banned. Before ordering, please check all local laws to be sure the Anti-Gun Nazis have not banned you from owning this unit or any part of it. No sales to Commiefornia, New York or Connecticut. If you live in any of these states– MOVE!
