I saw a Detonics Combatmaster MK VI marked Seattle WA at a gun shop yesterday and am interested in buying it. The gunshop owner has asked me for an offer and I have no idea how much it is worth. It is in almost perfect condition (98%) and comes with the original magazine and owners manual however there is no box. It also come with two sight blades, one with white dots and one solid black. It has wood grips on it. I have never seen a Detonics but when I picked this thing up it felt better than any gun I have ever held. I want it! I just need some advice as to how much to offer.
