AceTech QUADRA S Tracer Unit for Pistols
AceTech QUADRA S is finally the right tracer unit for airsoft pistols. Thanks to the combination of RGB Bifrost BB illumination and a gas-reactive muzzle flash simulation, shooting feels highly realistic and adds a colorful edge to CQB games. Compared to standard tracer suppressors, it features an ultra-compact compensator-style design, allowing it to fit even into open holsters such as Safariland 579 and its replicas like WoSporT GB35 / GB34 and FMA GLS 579. In use, the shake-to-wake function, fast mode switching, and reliable performance up to 35 BBs per second stand out, which is no issue even for advanced AAP-01 upgrade builds. The CNC aluminum construction is built to handle metal slides, and thanks to USB-C charging, the unit is always ready for action (USB-C cable not included).
Key Features of AceTech QUADRA S Tracer Unit
Realistic muzzle flash
3 powerful LED diodes simulate a shot based on gas output, creating a natural and immersive effect.
3 operating modes
Choose between RGB tracer illumination, muzzle flash only, or a combination of both depending on your playstyle.
Compact compensator design
Small body follows the pistol profile and works flawlessly even in open holsters like Safariland 579.
Automatic activation
The unit wakes up by shaking and automatically goes to sleep after 5 minutes of inactivity, saving battery power.
Durable CNC construction
Aluminum body with anodized finish withstands regular and dynamic use.
