AceTech Bifrost M Drop-In RGB Rechargeable Tracer Unit, Black

When you're playing a night game or a tight indoor match, you can't see where your rounds are landing. That's the problem the Bifrost M solves: a bright green LED illuminates tracer BBs from muzzle to impact, so you can see the arc and adjust your aim mid-burst.

Here's what makes it different from basic tracers. The AceTech Bifrost M adds a multi-colour RGB flame effect with 11 selectable modes that simulates muzzle flash. It's purely visual, but it looks good, and it's the kind of detail that separates a functional tracer from something that actually stands out at the field.

The flash effect depends on what's in the air. Fog, smoke, or just the muzzle blast's own gas column scatter the light and amplify the visual impact. In still indoor air, you'll still see it — just not as dramatic.

Fire rate won't be a bottleneck. The Bifrost M handles sustained bursts up to 35 rounds per second, so high-output AEGs and fast-trigger builds won't leave the tracer behind mid-burst.

Size and weight. It's 54mm long and weighs just over an ounce. Aluminum body with plastic internal components. You won't notice the added length at the muzzle, and the weight is negligible.

Modular drop-in design. The tracer mounts inside a compatible mock suppressor, giving you a cleaner profile and something for the flash to scatter against. The included adapter handles most setups.

Power. Built-in rechargeable Li-Ion battery. No disposable cells to keep buying. You charge it with the included cable and swap it out when the indicator tells you it's running low.

Thread compatibility. 14mm CCW threading, which is the airsoft rifle standard. It'll thread onto most gas blowback rifles and AEGs directly.

Before you buy. You'll need green tracer BBs — the unit's internal LED is tuned to illuminate those, and the BBs aren't included. Green tracer BBs are the standard kind available at any airsoft shop. The unit is a tracer, not a flash hider or regulator — it lights BBs, it doesn't manage gas or pressure.
