The RD 603 Mk.II Thunder Ranch Edition is the Ultimate Urban AK designed for the Ultimate Urban Rifle Class. The extruded aluminum Mk.II handguard is the perfect optics mounting platform for Red Dots, LPVOs, & IR aiming devices that holds zero, even when the rifle is field stripped. These special edition rifles all feature the Forward Controls Design 6315KM Flash Hider standard and are available in three colorways: CR Grey with Black accents, Folliage Green w/ OD accents (a throwback to our first Thunder Ranch AK), and our ever popular Tigerstripe finish. Additionally these rifles will feature an exclusive Thunder Ranch engraving on their receiver.
