Drozd is made in Russia by IZH-Baikal. It uses a standard 12-gram CO2 cartridge and six AA batteries. There are three switches to operate the unique select-fire mechanism. The first one turns on the gun. The second one selects the firing mode: semi-auto (one shot with each pull of the trigger), three-round burst (full-auto) or six-round burst (full-auto). The third switch controls the burst rate: 300 rounds per minute, 450 rounds per minute or 600 rounds per minute
