RE: What' s my used Omega worth?
Dorr they are hot right now, we sell stainless with black stocked 50s at my brothers place for $429.99 if I remember correctly (a rarity indeed!). The scope isnt worth much but at least you got it based, ringed and ready for a change if need be. I would ask $300 and take no less than $250 for it right now. If you have an extra $100 or so in accessories then throw that in for $300 or an extra $25 if they offer you $250 for the gun.
What are you replacing it with?
