U.S.-assembled by Riley Defense, this RAK308 leverages a surplus Yugoslavian M77B parts kit and a Tortort-manufactured, milled, heat-treated steel receiver. The receiver is marked "RILEY DEFENSE INC HICKORY, NC / RAK308 / CAL .308."
The barrel is 4150 steel, nitrided, and measures 19.65 inches (listed nominally as 20 inches). It is threaded 14x1 LH and comes fitted with a multi-port muzzle brake. The nitrided treatment supports durability and corrosion resistance in hard-use calibers like .308 Win.
A 3-position adjustable gas regulator pairs with the long-stroke piston, rotating-bolt action, giving the user three settings to regulate the system for different conditions and ammunition within the .308 Win chambering.
Sighting is classic Yugoslav pattern: a protected front post and a tangent rear sight leaf, with flip-up night-sight elements noted by factory literature. For optics, the rifle includes the Yugoslav-pattern left-side rail to mount compatible side-rail optics.
Furniture includes a solid wood fixed stock with a steel buttplate, two-piece wood handguards, and a brown polymer pistol grip. Capacity is 20+1 with Zastava M77-pattern detachable box magazines. Overall length is 41.5 inches, weight is 9.5 lb, and length of pull is 13.5 inches. The rifle wears a blued finish.
