Acetech Bifrost Tracer Unit; Lancer Tactical Special Edition

Code: A68591
  • Special Edition Bifrost Tracer Unit
  • Heat Gradation Rainbow effect finish
  • For 14mm CCW male threads & 11mm CW female threads

You've heard of the legendary Bifrost tracer unit, but this new Acetech X Lancer Tactical special edition takes the most stylish tracer unit on the market and bumps it up a notch with a gorgeous heat gradation/rainbow effect finish which is sure to draw eyes in game and would be the perfect companion to a loud and proud high rate of fire build.

As with the original Bifrost, this compact Acetech tracer unit offers a plethora of functions including muzzle flash simulation, selectable colours for the LED array, Rainbow and Dynamic Rainbow mode as well as the option to run the unit as a simple tracer unit for when you want to be more discrete and sneaky. The unit mounts to 14mm CCW male threaded barrels but also comes with an 11mm CW to 14mm CCW adapter, meaning it can also be mounted on any pistol with 11mm CW female threads. With all the options under the sun and the ability to keep pace with extremely high rates of fire (up to 35 rounds per second!), this is probably the ultimate Airsoft Tracer unit!

BBs frequently purchased with this unit...


The Acetech Bifrost tracer unit redefined what a tracer unit can do, combining tracer functionality with realistic muzzle flash and then spicing things up with a whole spectrum of colour options and the ability to make standard white BBs glow like a rainbow for the first meter of so of their journey down range.

The Bifrost offers two modes of operation when it comes to the basics, with about a million other modes when it comes to setting your colour of choice, whether it be a single colour or all of them in concerto! The first mode is known as "Standard Mode", and will provide an epic muzzle flash in a colour or colour combination of your choice with each shot as well as illuminating Green tracer BBs, giving you improved instinct aiming capability in low light.

The second mode is known as "Sniper Mode", and will illuminate your BBs but keeps the muzzle flash turned off to aid in concealment. This is important when stealth is a priority, whether in CQB or outdoors, as the muzzle flash is so bright it will definitely draw eyes and if you are the sneaky type you will want to avoid this.

When you are in "Standard Mode" you can select the colour of your muzzle flash using the Flame selection button inside the case of the Bifrost, with Rainbow, Dynamic Rainbow, RGB and various single colour options to choose from. To access the button, simply unscrew the rear cap to reveal the charging port, the Mode selection button and the Flame selection button. The Mode selection button allows you to scroll between Standard and Sniper modes, and the Flame selection button lets you choose the colour of your muzzle flash. The charger port is of the USB Type-C variety and the cable to charge the unit is included in the box.

The Bifrost mounts to 14mm CCW male threaded outer barrels directly but also includes an 11mm CW female thread adapter in the box, meaning it will fit most Airsoft AEGs and GBBRs and with the adapter, you can mount it to WE/Armourer Works GBB pistols or any others which have an 11mm CW female threaded outer barrel. If you have a RAVEN, VORSK or Army Armament pistol fear not, you can mount the Bifrost using an aftermarket 12mm CW female to 14mm CCW male thread adapter, so you won't be left out!

This particular variant of the Acetech Bifrost has been commissioned by Lancer Tactical and has subtle Lancer Tactical markings on the rear cap and another, slightly less subtle clue that this Bifrost is something a bit different. The outer case is finished in a gorgeous "Heat Gradation" AKA "Rainbow Effect" coating, making the unit really pop, even when it's turned off! This Lancer Tactical Special Edition Bifrost would be the icing on the cake of any Heat Gradation build, and would give any AEG or GBB a stylish accent which is sure to turn heads!

Equally useful for an aggressive skirmisher who has nothing to hide as it is a sniper looking for a discrete way to track their BBs trajectory at long range or in low light, the sheer number of options the Acetech Bifrost Tracer Unit presents renders practically every other unit obsolete!
