BlowBack kaasupistolit (GBB)

Gas-operated, self-loading, semi-automatic and fully automatic airsoft gas pistols equipped with a BlowBack recoil mechanism. When shooting with a Gas Blow Back (GBB) gas pistol, the Blowback mechanism moves the slide with each shot, reloads the bullet into the barrel, and at the same time brings recoil to the weapon. Gas guns use so-called bottled gases (e.g. Green Gas). The gas is usually loaded into the magazine through a valve at the bottom of the magazine.
