It is a Lipsey's Ruger RSI International, stainless, in 7x57. This one has a 1:8.75 inch twist, an 18.5 inch barrel, and is built on the M77 Hawkeye action.
The M77 Internationals are very nice rifles indeed, esp in a classic chambering like 7mm Mauser. Topping that with a XVIII 1.5x5 would be perfect.
The only critique I would have for the rifle is I'd like to see it in a 20" bbl with the forend and bbl trimmed down to maintain balance and not look so chubby up front as it does.
