Our favourite Kiwi, Nonocat, tries the Acetech Quark K, the tracer for use with Marui KSG airsoft shotgun and here is what she says about it... "Acetech has done it again and this time with the world's first Airsoft Shotgun Blaster unit! Designed exclusively for the Marui KSG Shotgun, the Quark is not only a RGB Blaster and a tracer unit, but it also comes with an integrated motion controlled flashlight system! To push it even further, Acetech has now developed a Bifrost unit capable of shooting both green and red tracer BBs at the same time! WOW! Let's see how it works in this video with Nonocat!"
