Used item. Very good condition. Some wear on the end of the buttstock, and on the turn knob, showing some down to the metal. Otherwise, fully functional and you will be happy.
This is the real deal, from Knights. Hard to find, harder to buy. This is what you need for your M110 clone, or just a really cool AR. We seldom have in-stock, but occasionally will take a lot in from surplus vendors and collectors.
