ACETech KSG Shotgun Quark K Bifrost Tracer Unit

The ACETech Quark K is a revolutionary tracer unit designed for the Marui KSG gas Airsoft shotguns. This tracer unit doesn't only look cool and has similar design cues to the KSG itself, it also has a bunch of useful built-in features.

The Quark K has a built-in tactical flashlight that is not just bright, it also has 3 different modes, a manual mode, a strobe mode that flashes 10 times per second, and a motion-sensing mode that switches the light on when the tracer is facing up or down. The tracer itself is an enlarged Bifrost so you can expect 11 flame effect modes just like a regular ACETech Bifrost tracer would. Unlike most tracers, the Quark K is able to work with different color tracer BBs and not just the usual green ones.


Bifrost simulates muzzle flash, the flame-effect depends on volume of gas or water fog around the muzzle
Two modes integrated: Tracer (11 colors selectable) / no Tracer (Sniper Mode)
