The CZ-USA 1020 G2 in black-and-gray dress is a 20 gauge semi-auto shotgun (CZ-USA part no. 06136) that shares the same inertia-driven operating system as CZ’s full-size 1012 G2, just scaled onto a lighter, 20-gauge-specific receiver. A black barrel paired with a gray receiver gives this variant an understated, modern look next to walnut furniture that keeps the classic feel CZ shooters expect. Oversized controls speed up safety and bolt manipulation in the field, and the factory Weaver-style rail is ready for a red dot when fast target acquisition matters most. Light recoil, dependable cycling, and a versatile chamber make this 1020 G2 equally at home on a dove field or in a turkey blind.
