CZ 600+ ST3 American

About the CZ 600+ ST3 American

The CZ 600+ ST3 American is the long-magnum-action member of the upgraded CZ 600+ line, built on the larger ST3 receiver to chamber full-length and magnum cartridges such as .30-06 Springfield, .270 Winchester, and .300 Winchester Magnum. Like the rest of the 600 series it uses a user-interchangeable switch-barrel system, a single-stage adjustable trigger, controlled-round feed, and a Remington 700-pattern receiver, dressed in laser-checkered Turkish walnut with a satin-blued steel finish and a 24-inch threaded barrel.

The CZ 600 series was engineered around user-swappable barrels, letting an owner change calibers at home with a torque wrench; the ST3 magnum action extends that modularity to long and belted-magnum cartridges.
