I built a replica of the C4 from CS2 with fully functioning and accurate electronics! If you work for a three letter agency please have mercy...
Please note that I am very careful with the storage and transportation of this replica. I keep it in a clearly labeled box explaining that it is not dangerous and I never leave it unattended outside the box. Projects like this should always be conducted with care regarding safety and the perception of members of the public.
There are no firearms in the video. Only airsoft replica props were used.
