{"id":15911205929334,"title":"Acetech 'Quadra S' Tracer Unit","handle":"acetech-quadra-s-tracer-unit","description":"

The Acetech Quadra S Tracer Unit takes the compact compensator-style design of the original Quadra and adds Acetech's full Bifrost RGB muzzle flash system, giving you considerably more control over how each shot looks.

Its compact square-profile design is particularly well suited to pistols, sitting much closer to the profile of the slide than a traditional cylindrical tracer unit. At just 45.5mm long and approximately 50g, it keeps additional length and weight to a minimum while giving your build a completely different look.

The big difference between the Quadra and Quadra S is the muzzle flash system. The Quadra S adds Bifrost RGB functionality with 11 multi-colour flame modes, alongside the standard orange flame effect. You can run Tracer + Flame, Flame Only or Tracer Only, allowing you to switch between a clean tracer setup and the full RGB effect.

Both red and green tracer BBs are supported, with the Quadra S capable of keeping up with firing rates of up to 35 rounds per second. Standard BBs can also be used when you just want to take advantage of the muzzle flash effect.

The housing is constructed from CNC-machined aluminium, while an internal rechargeable lithium battery and USB-C charging keep things simple between games. It also features automatic wake functionality and enters sleep mode after approximately five minutes of inactivity to help conserve battery life.

The Quadra S uses a 14mm CCW thread and includes an 11mm CW to 14mm CCW adapter, making it suitable for a wide range of threaded airsoft pistols and rifles. An adjustable alignment system also allows the square body to be correctly positioned once fitted.

If you like the compact design of the standard Quadra but want the full Acetech Bifrost experience, the Quadra S is the one to go for.
