BNIB, Recently picked this up but only have two scoped rifles and I sighted them in before it came. It is a Sighting System Instruments, model LBK-DX for pistols, rifles and shotguns, .17through .50 cal. 410 though 12 ga. Brand new with everything they come with including batteries. Looking for $50 or possible trade for ammo: 7.62x39, .223 or ?
