 The Blackbird boasts a 400-round-plus capacity, as well as an improved three-cartridge 12-gram CO2 system, or a single 88-gram large CO2 cartridge.It shares many parts with the original "Drozd" and retains the same basic body configuration, as well as the original "Drozd's" stock firing modes.Some have criticized the new Backbird for having an overall cheaper "plastic" appearance, but the large magazine capacity makes it completely different kind of gun than the original Drozd.
