Optics-Ready Slide

The ORS optics-ready slide supports direct-mount RMR-footprint red dot sights. An additional adapter plate expands compatibility to RMR, RMSc, and DeltaPoint Pro footprint optics.

The fixed-mount optics design provides a stable aiming platform by keeping the optic isolated from the reciprocating portion of the split slide.

The red dot optic is not included with this version.

Adjustable Blowback System

The Performance Refined Edition features a CNC aluminum adjustable blowback housing with tunable airflow timing.

This allows the blowback system to be adjusted to help tailor cycling characteristics and gas efficiency to the user's preferred setup.

Hop-Up System

An external adjustment dial provides quick, tool-free hop-up tuning without requiring normal slide disassembly.

The wide adjustment range is designed to support BB weights up to .40g.

Compatibility

ARCTURUS specifies a high-compatibility design with approximately 60% individual parts or 100% assemblies compatible with the Tokyo Marui Hi-Capa platform.

Individual aftermarket component fitment should still be verified before installation.

CO2 Magazine Notice

This pistol is not directly compatible with CO2 magazines in its standard configuration. ARCTURUS specifies that the long cutoff delay spacer must be installed before CO2 magazine use.
