Acetech BI-Frost MKII Tracer Unit

Multi-Colour Rainbow Flame Effects. Hyper-Bright Tracer Illumination. Next-Gen Bifrost Tech.

Light up the night and dominate CQB arenas with the Acetech Bifrost MKII Tracer Unit. Building on the legendary success of the original Bifrost, the MKII brings Acetech’s advanced multi-colour rainbow flame technology into an upgraded, ultra-compact suppressor housing engineered for high-speed airsoft builds.

Equipped with high-intensity RGB LEDs and smart beam-tracking optics, the Bifrost MKII simulates vibrant rainbow muzzle flashes, fiery orange blasts, or single-color tracer streams with every pull of the trigger. Whether mounted on a CQB primary rifle, submachine gun, or GBB pistol, the MKII turns every burst into a stunning visual display while charging green tracer BBs to laser-bright intensity downrange.
