The rails are all unused, unless marked. Some are "new old stock," so, yes, new in the box, but 15 years old. Then, we buy complete rifles and URGs, and gently remove the rails. Those are new "take-offs," and yes, we put them in a box and yes, we have the hardware. There is no difference, as long as some idiot does not ding the rail.
At Charlie's we are direct Daniel Defense dealer. Our access to DD parts and are prices are as good as it gets.
Includes hardware, does not include a RIS wrench.
