Some lightshow fun for DTW Airsoft as he tries the Quark-R tracer unit from Acetech... "This time im looking at the Acetech Quark-R. This is an airsoft tracer unit designed to be used on most M870 style airsoft shotguns. With the ability to illuminate both red and green tracer BBs along with giving standard BBs a little glow as well when it leaves the barrel. Along with the tracer function it also has 11 flame colours just as you would find on the original Bifrost, giving you that rainbow tracer effect."
