In the circles I run in those run 1500-2000 bucks and are highly desirable. If it makes weight in current form at 8lbs 8oz or less then it's even more desirable because it can be used in hunter gun class. If it's not that light but still at or under 10lbs 2oz then it'll still work as is for smallbore standard gun metallic silhouette.
If you want to know for sure sign up at steelchickens.com and ask them. If you're looking to sell, that's the place to sell it.
EDIT: The valuation above is irrespective of the optic and does not include it.
