Type: BB air pistol. Manufacturer: Cybergun. Model: Mini UZU. Materials: Metal and Polymer. Weight: 4.8 pounds. Barrel: Metal, non-rifled. Propulsion: CO2 x1. Action: Semi auto (Selectable Full Auto with Mod) blowback, single action only. Ammunition Type: Steel BBs 4.5mm. Ammunition Capacity: 25 rounds FPS: 344 This is a really nice blowback BB gun. Although it is advertised on many websites as being all metal, it does have some plastic outer parts, but the parts that get the most wear and tear are made out of metal. That aside, the Cybergun Mini UZI is pretty much an exact copy of the real Mini UZI with many of the same markings as the original. One feature that makes it feel even more genuine is the very heavy blow back recoil, it is alarming at first and I would even say it has more recoil than a rimfire 22 cal. gun does. It only comes in a semi auto version but all Cybergun did to inhibit full auto mode was to simply add a plastic nub that stops the fire selector switch from being selected to full auto. Once this plastic nub is removed, full auto mode is resorted. This well made BB gun is a bit pricy but you get a lot of gun for your money!
