Another take on the Acetech Bifrost tracer unit with this video from JKArmy... "The Bifrost simulates muzzle flash, with Multi-color flame effect.The effect of flame depends on volume of gas or fog around the muzzle, more volume makes better effect. Also, the Bifrost provides colored BBs track function which can be achieved by standard BBs with the built-in RGB Flame LED.

Acetech's latest tracer unit and a multi-coloured one at that, the BiFrost, gets scrutinised by Hyperdouraku... "Introducing the ACETECH tracer, Bifrost with a video.
If you wear a tracer in a night game and shoot an air gun, you can enjoy it as if it were fireworks.

This bi-frost is a super fun rainbow-colored tracer that shines in 7 colors with a further evolution of the muzzle flash function!"

Go multicolour firing with your airsoft gun as the new Acetech BiFrost tracer unit allows you that. This tracer unit has 11 modes such as: 7 X Mono color, RGB multilayer, Bifrost, Dynamic, and Demo and can be used with standard BBs, Green tracer BBs as well as Gel BBs for Gel Blasters. It also has a Smart Power Saving System: Shake and Wake for quicker kick-off. Jonathan Higgs takes a look at this muzzle device in this Airsoftology review.

The new Acetech BiFrost Tracer Unit promises even more colours to use in a game and 4UAD Smart Airsoft gets to unbox one to find out if it does what the company says and even more tracers to have fun with in this video... "Tracers and blasters are the new thing for airsoft from the past 5 years, now days these little gadgets become the must have for some CQB players! This time after visiting Acetech, we got a bunch of tracers and wireless targets, gotta say we had a whole lot of fun!
