Construction & Reliability

Constructed from aluminium alloy, the Quark R offers a durable and lightweight build suitable for regular skirmish use. The rotatable collar system allows for secure mounting on unthreaded shotgun barrels, while maintaining clearance for front sights or extended magazine tubes.

The rear cap conceals controls and the charging port, protecting internal components from dirt and debris. Included O-rings and gaskets ensure a secure and stable fit across compatible platforms.

Performance & Field Use

The Quark R is designed to enhance shotgun gameplay by improving shot visibility and adding realistic visual effects. In Standard Mode, it produces a bright, configurable muzzle flash alongside tracer illumination, making it easier to track shots and improve instinct aiming in low-light environments.

Sniper Mode disables the muzzle flash while maintaining tracer functionality, allowing for more discreet use when stealth is required. Multiple lighting modes, including RGB, Rainbow and Dynamic Rainbow, provide customisable visual effects to suit different playstyles.

With features such as shake-to-wake and automatic power-off, the unit ensures efficient battery use while remaining ready for action during gameplay.
