Our AirsoftPro steel cylinder was sucessfully tested on the strongest springs. Made on CNC machines. The steel seamless tube and the steel mandrel of the bolt handle are firmly welded in four places. The weld was polished to make the movement smooth. The set is chemically blackened - burnished, as protection against corrosion. Nevertheless, it is necessary to lubricate as a real weapon.
