Grab the banger and bring it to the ground floor. Go outside, get a beacon from the vendor machine. Drop both the Banger and the beacon somewhere WITHOUT a ceiling.
Grab the beacon, hold left click and wait until it activates. Drop it as close as possible to the Banger and move several steps back. Watch the whole sequence. Sometimes the first beacon will not be able to completely destroy the Banger. Simply repeat the process until the ray makes the Banger disappear.
