Our Assessment: The Interarms Mark X Whitworth Express Rifle is a classic Mauser-pattern sporting rifle, combining Zastava manufacture, Whitworth branding, and Interarms importation into a traditional dangerous-game style hunting rifle. This 1975 C&R-eligible example is chambered in .375 H&H Magnum, one of the world’s great big-game cartridges, long respected for its penetration, reliability, and use on large and dangerous game. This rifle features a 24″ barrel, express-style rear sight with additional 200- and 300-yard folding leaves, beaded front sight, checkered walnut stock with ebony forend tip and shadowline cheekpiece, barrel-band sling stud, and a Leupold M8 Compact 4x scope mounted in hinged Weaver rings that allow the optic to swing aside for use of the iron sights. The .375 H&H chambering, Express Rifle configuration, classic walnut-and-blue presentation, and dual optic/iron-sight setup should appeal to hunters, collectors, and enthusiasts looking for a traditional safari-style rifle with practical field capability.
