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.

BZ Tech Team Advice:
Mode Switching Made Easy: Cycle through lighting modes instantly by pressing the rear power button. Switch to fiery red/orange for milsim immersion or turn on full Rainbow Mode for speedsoft and night skirmish content!
Tracer BB Choice: To get both a vibrant muzzle flash AND glowing laser lines downrange, always load high-quality 0.20g or 0.25g Green Luminous Tracer BBs.
Pistol Mounting: When installing on tilt-barrel GBB pistols (like Glock or Hi-Capa platforms), ensure your outer barrel can handle the tracer weight or use a thread-adapter spacer to preserve smooth slide cycling.
