The RT-S Mod 7 is Riton’s top line, and where both the new 1-8×28’s reside. This line goes head-to-head and toe-to-toe with the best and most expensive optics on the market today—at a much greater value to the consumer. From the 30mm or 34mm main tube to high-end Japanese glass to push/pull locking turrets or the Argon-purging process that makes this scopes completely waterproof, fogproof and shockproof, these and all of Riton’s scopes are covered by Ritons’s Lifetime Replacement warranty.
