Light Up the Night - AceTech Quadra S Bifrost Red & Green Pistol Tracer Unit (Black)

Ready to take your low-light engagements to the next level? The AceTech Quadra S Bifrost isn't just a tracer unit - it is a multi-mode light engine designed to turn your shots into cinematic beams of light. Combining AceTech's world-class tracer technology with the stunning "Bifrost" multi-colour flame effect, this compact unit is the perfect addition to any pistol or short carbine setup.

Key Features & Performance

• Dual Tracer Support: Features high-power LEDs that efficiently illuminate both Green and Red tracer BBs for maximum visibility.
• Bifrost Flame Effect: Mimics muzzle flash with a stunning multi-colour gradient, allowing you to choose between single colours or a full RGB "Rainbow" mode.
• Compact & Lightweight: Specifically designed for pistols, the Quadra S is small enough to avoid interfering with your sight picture or holster fitment.
• Intelligent Power Management: Equipped with an auto-sleep mode that preserves battery life during long periods of inactivity, waking up instantly when movement is detected.
• USB-C Rechargeable: Built-in Li-Po battery that charges quickly via the included USB-C cable, providing thousands of rounds on a single charge.
• IP64 Weather Resistance: Dust and splash-proof construction ensures your tracer stays functional even when the British weather turns against you.

The "Pro" Take

AceTech has dominated the tracer market for years, but the Quadra S Bifrost is a specific favourite for the modern "Speedsoft" or CQB player. The ability to switch between standard tracer functions and the "Flame" mode gives you a massive psychological advantage in dark environments. What we love most about this unit is the versatility; it comes with an 11mm CW to 14mm CCW thread adapter, meaning it fits almost every GBB pistol and AEG rifle on the market right out of the box. It is reliable, flashy, and built to withstand the rigours of aggressive play.

UK Spec & Site Performance

Tracer units are an essential tool for many UK indoor CQB centres like "The Department" or "StrikeForce," where lighting is kept low to enhance the atmosphere. The Quadra S Bifrost is particularly effective in these environments as it helps you track your shots in real-time, allowing for instant aim correction without needing to look at your sights. At outdoor sites during twilight games or night ops, the "Bifrost" mode acts as a brilliant deterrent, often confusing opposition players who aren't used to seeing a rainbow-coloured muzzle flash. As this is an accessory and not a RIF, no UKARA is required to purchase, though it is designed to be used with standard UK-legal airsoft platforms.

Friendly FAQ

Does it work with standard BBs?
The "Bifrost" flame effect will work with any BB, but to see the glowing "laser" beam, you must use dedicated Tracer BBs (Green or Red).

Will this fit my AAP-01 or Glock?
Yes! It features a 11mm CW thread (standard for many pistols) and includes a 14mm CCW adapter, which is the standard thread for most airsoft rifles and the AAP-01 muzzle.

How long does the battery last?
A full charge can last for up to 20,000 rounds depending on the mode used. The RGB flame modes use slightly more power than the standard tracer-only mode.

Can I use this on a gas blowback rifle?
Absolutely. The Quadra S is designed to handle the vibration of GBB platforms and can support a rate of fire up to 35 rounds per second without missing a shot.
