The 10 FCP-SR seems to be a discontinued model - based on the Savage web site.
I have seen it there before on that site.
The 10 FCP designation is for a Law Enforcement model with a detachable mag and the -SR indicates it is suppressor ready.
As I remember, it only came in the black Accu-stock version.
There is a 10 FCP-HS that is still available on the Savage web site but that model comes with a High Precision Stock with a high cheek rest and aluminum V-block that raises the price by a lot and the overall weight is heavier. It also doesn't have a Suppressor Ready barrel. It does not come with the high single piece scope mount included. The frame is the same but the stock is different.
If I remember correctly the 10 FCP-SR listed on the Savage site under $900 but most sellers would price it for a lot less.
A shooting buddy bought a new 10 FCP-SR for just over $650 in 6.5mm Creedmoor.
Cabela's sells a similar model 10T-SR made for Cabela's exclusively (a model 10 FCP but it comes with a standard 4 round Savage magazine instead of the 10 round mag and without the single piece scope mount). I bought mine for $550.
Personally, I have a single piece scope mount on a 11VT and I think it creates too high a scope mount for the lower cheek rest on the Accu-stock.
It appears the seller may have changed the stock and is pricing up to $300 more the normal sales price.
There are no differences in the 10 FCP-SR standard rifles as there were no options once it was designated as an FCP-SR.
What you are seeing is variation in the prices that sellers put on offerings.
In this case it appears that a seller is inflating the price for what looks like a used rifle.
If it is not listed as 'New in Box' I would be suspect.
Since the box is missing, the 'new' designation could be the buyer's interpretation of slightly used or as a result of a stock replacement.
A up front seller would include all that information in his listing.
Let the buyer beware.
