The CS3 Pro is built for pure performance and now leveled up with our exclusive HK Army Shredder milling. Powered by the OP Drivetrain, it runs at ultra-low pressure for unmatched consistency, efficiency, and reliability...no tuning needed.

A redesigned foregrip with concealed breech sensors creates a sleeker stance while keeping paint and debris out of your electronics. The OLED screen adds NXL Pro presets for fast checks, and the adjustable Deuce trigger delivers pro-level speed with a Blade trigger included for preference.

Finished with the upgraded S63 Pro 3-Piece Barrel System featuring the HK Army Elite Fossil back, this is the CS3 Pro—refined, streamlined, and built to win.
