Your gun may be marked Drozd, IZH-Drozd or MP-Drozd and may have any one of these mfr names: IZH, IZH-Baikal or Baikal. They all come from the same plant and are manufactured to the same specs. The guns are identical.The 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.The gun comes with a detachable shoulder stock (increases length by 5.75), scope rail, sights, one 30-round magazine and a BB loader. The magazine holds the ammo and the CO2 cartridge. This black Russian wonder is great as an all-day plinker. If you'd like to mount a pistol scope or red dot, that's easy enough with the 11mm dovetails.Ninety-day limited repair warranty on factory defects of the metal parts, and a 30-day warranty on seals.We also offer an upgraded version that includes a durable aluminum pistol case (18Lx13Wx5H) with keyed latches and three layers of high-density foam. Shoot all day! A fun gun that's great for plinking.
