ACETECH has been leading the industry in the tracer unit segment with unique designs and innovative technology.  The Bifrost module is their new breakout product and is a prime example of this.

Internally, the Brighter M is packed with great technology.  Along with its base function of being a tracer module, it also features front-facing LEDs to simulate muzzle flash.  This muzzle flash mode can even be used as a standalone feature along with the two other modes: tracer only and tracer + muzzle flash combo.  It also comes standard with its intelligent power control.  It will enter sleep mode after five minutes of being idle and will instantly wake upon shaking it.  However, where the Bifrost differs from others, even in ACETECH's own lineup, is the ability to have a multi-color effect.  As you shoot, your tracer unit can project a different color upon your BBs giving it a rainbow line of BBs coming out of your tracer unit!
