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."

Nonocat gives her take on the Acetech Quark-R Bifrost Tracer Unit made for use on the Tokyo Marui M870 airsoft shotgun... "Since Acetech released the Quark-K for the Marui KSG, everyone have been asking for a M870 Bifrost... Well, all prayers have been answered graciously with a much solid and adaptable unit for one of the most used Airsoft shotguns!

UntangleWorks tries the Acetech Quark-M and Quark-R tracer units for airsoft use if they can also work with paintball... "Here do I talk about the Actech Quark R  and Quark M tracer that can be used for 68 cal paintball markers to be fair this is not the only option. The Umarex T4e TR 68 X-tracer is also a option, but I will be testing that model on a later date. And make mounds for that tracer as well."
