Schmidt & Bender 3-12x50 PM II Tactical Rifle Scope.

I recently upgraded my scope and i am looking to sell my old one. It is a Schmidt & Bender 3-12x50 PM II Tactical Rifle Scope. The scope brand new goes for around $4000 and used goes for around $3500. I am looking to get around $2,000 but can be flexible and will include photos if you would like to proceed.
