Another tracer unit for Airsoft Mike to unbox and give his first impression and it is the more recent release by Acetech, the Bifrost BT. This is a multi-functional tracer unit designed to augment the realism of airsoft and gel BBs. It is capable of simulating a multi-colored muzzle flash, the intensity of which is contingent upon the volume of gas or fog surrounding the muzzle.

The larger the volume, the more pronounced the effect. Additionally, Bifrost offers a colored BBs track function that can be achieved with standard BBs through its built-in RGB Flame LED. Users are afforded the flexibility to select between two tracer modes: Standard and Sniper. The multi-color flame function enhances the visual appeal with 11 different modes available. Bifrost also incorporates intelligent power control, with the Blaster Module activating by shaking and entering sleep mode after remaining idle for over 5 minutes.

This amalgamation of features renders Bifrost suitable for both standard airsoft and gel BBs.
