SVD GBB - black - full metal, blowback

Airsoft sniper rifle SVD (Dragunov) is well know gun. Specifically spring action version. It is favourite due to its low price, long barrel, trouble-free and simple construction. Now coming to the market semi-automatic version of the rifle. It looks like standard spring action version. Uses same outer metal body.  But we found the difference immediately after removing the magazine. It is very heavy because of the inner gas tank. Mag is filled with classic valve at the bottom side for about 7-10 seconds. Magazine capacity is 22 rounds. Package include just gun, magazine and the farepiece. The reason why choose a gas version of the SVD is particularly high realism and excellent price-performance value. You have to pull back cahrging handle after magazine insert.  This cause very realistic sound of the metal mechanism. Internal trigger mechanism is similar to the real one and of course made by metal. When a shot is fired, whole receiver block strongly kick back. Excellent feeling of the realism.  Receiver remain in a back position once you shoot last BB. Gun uses standard AEG barrels in a length 590 mm (can use up to 650mm) and standard HopUp buckings. With classic green gas rifle shots approximately 120-150 m/s (380-550 FPS). Depending on the outside temperature and and weapons. Manufacturer and importer recommended to use Green Gas. However, with Red Gas  power can easily reach much higher FPS.
