This is a discontinued model from Daniel Defense that has been in my safe for a few years. It is in almost new condition (I can't see any marks). I haven't kept a round count, but I can assure you it's VERY low. I shot it a few times just to sight in an optic that I used to have mounted. I also have the original case (not pictured). You can probably see from the pictures that the barrel is threaded. I tried it with my suppressor, and this thing would be an awesome hunting setup for small game. It comes with a two stage Geissele trigger from the factory (gun is 100% stock/unmodified). I also have the original box and packaging (not pictured).
