The package includes a reduction from the left-hand M14 thread to the right-hand M11, so you can use the silencer on any airsoft gun that has a detachable protrusion.

The mode button controls the tracer function: Standard - which illuminates every shot, Sniper - which illuminates every third shot and doesn’t have the ‘flame’ effect and the tracer off function. Whether it's a pistol, rifle, sniper, or machine gun powered by AEG, HPA, GAS or Spring, each of these beasts needs quality feed, or they'll be naughty. Now this is an interesting piece of kit not only is it an airsoft tracer unit compatible with green tracer bbs but you also get front-facing LED's designed to simulate a muzzle flash.The flame button controls the colour of the ‘flame’ and it has the following colours/functions: red, orange, yellow, green, blue, pink, purple, RGB (where the flame flashed red, green and blue), rainbow and dynamic rainbow. The intent is to display an ad that is relevant and interesting to the individual user and thus more valuable to third-party publishers and advertisers. That description isn’t the best so I’ve taken some stills from my product tests and you can check the videos out for yourselves here!

It is powered by an internal Li-Ion battery that fully charges up to 24,000 bbs or 12,000 in lighting and flame imitation mode.Even better the tracer can be made to light up your BBs in different colors giving you that space-age blaster feel.

Acetech have designed a whole new type of device, a tracer unit which has the added feature of simulating multi coloured muzzle flash. With intelligent power controls and a long-lasting battery, the Bifrost ensures seamless operation and can handle up to 20,000 rounds on a single charge. In practice, the most widely recognized form of defense for owning a RIF is membership in a registered airsoft club (UKARA). To access the button, simply unscrew the rear cap to reveal the charging port, the Mode selection button and the Flame selection button.

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 blast is best seen when used on gas weapons, when the remnants of the gas after the shot are lit. The Bifrost has no less then ten different settings, thanks to the range of colours hidden inside the unit.
