Product Overview

Built for CZ 550 and BRNO ZKK 601 short‑action rifles, the RUSAN Picatinny Rail CZ 550 ZKK 601 SA gives you a rock‑solid steel mounting platform without turning your rifle into a science project. Precision‑machined from high‑grade steel and finished in a deep blued black, it locks onto the 19 mm dovetail and sits low over the action so your cheek weld and handling stay familiar. At 125 mm long with 0 MOA inclination, it’s compact, tough, and ready for everything from bush stalking to range work.

The rail uses true Picatinny slot spacing (5.23 mm), so any quality Picatinny or Weaver‑style rings, red dots, or night optics will bolt straight up and stay put under recoil. Installation is straightforward: clean the receiver, slide or position the rail on the dovetail, then secure it with the supplied M5 set screws using a dab of thread‑locker and a torque driver. Once it’s on, you’ve got a stable, repeatable mounting solution that lets you swap optics with confidence and keep your CZ or BRNO working hard in Aussie conditions.
