As a Rossi 92 owner who follows Rossi forums, it seems to fill a niche that some owners express, from what I see online.

A subset of pistol caliber lever enthusiasts want a silenced Rossi 92 carbine with optics, and until now have had to accomplish it themselves. Still other owners like the idea but don't make the effort.

There is a blued version of this rifle, but as to the $858 MSRP price of the Cerakoted version (non-Cerakoted MSRP $668) pictured, a rough breakdown:

16 inch Rossi carbine, blued, on Buds: $531
Cerakote coating on complete bolt rifle: $295
Machine barrel muzzle threads and thread protector: $100
Aftermarket accessory rail (unavailable from Rossi): $32

For a total do-it-yourself price of $958 vs MSRP of $858
Non-Cerakoted DIY price of approx. $663 vs MSRP of $668

It may not float everyone's boat, but there is a market for it, and the price reflects the cost of components. The problem with Rossi is that not everything in the catalog makes it to market.
