Tracer Unit Acetech Thor QD Black incl. Bifrost M Module for Krytac Kriss Vector

The Thor QD Black by Acetech is a tracer unit specifically made for the Krytac Kriss Vector and is combined with the Bifrost M module. 

Acetech Thor QD Black tracer unit:
The Thor QD Black unit comes with the Bifrost M module which is interchangeable with any other Acetech module with a maximum length and diameter of, respectively, 73.5 and 28 mm. To replace the module within the unit, the cap on the front of the unit needs to be twisted a quarter of a turn in order to take it off. 

The Thor QD unit can easily be clicked onto the replica. To increase usability, Acetech made sure the unit can be attached directly over the flash hider of the Krytac Kriss Vector. At the underside of the Thor, you can find the quick detach button which releases the unit from the replica. 

Acetech Bifrost M module: 
The Bifrost M is the module which is included within the Thor QD black. This module supports a firing speed up to 35 RPS with green tracer BB’s or gel BB’s. In addition, the module meets IP-64 requirements, meaning it’s dustproof and can stand splashing water. It distinguishes itself from other Acetech modules by being able to simulate a multi-colour flame effect. 

Turning the Bifrost M module on and off has been made convenient through the built-in motion sensor. The sensor will automatically activate the module when movement is detected and when no movement is detected for more than five minutes, it will switch off again.
