CO2 Semiautomatic BB (4.5mm)
15 shot pistol
A British consumer's assessment
The CO2 cylinder is inserted into the grip and is surprisingly easy to replace .
I thought there may be the sound of escaping gas as the cylinder is punctured by screwing in the CO2 cartridge cover but this was not the case .
The BB's are fed into a 15 shot clip which is then slid up into the grip .
