CZ 600+ ST3 American
Česká zbrojovka · Rifle · In Production · 2026
Also known as: CZ 600 ST3 American
Overview
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.

Notes
Part of the 2026 CZ 600+ refresh. 24" (610 mm) tapered medium-contour barrel threaded 9/16x24, 3-round magazine, adjustable trigger 1.3-3 lb. The ST3 long/magnum action distinguishes it from the standard short-action 600+ American. Switch-barrel design allows owner barrel/caliber changes.
Background
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.
