Stainless steel cylinder for Well MB06, MB13

Most of the airsoft rifles have the air cylinder made of a thin aluminum tube and clamped or pinned to the bolt handle pin. This connection is relatively sufficient for base springs. But using a stronger spring deforms the pull lever from the cylinder. Durable steel cylinder is therefore a necessary addition to increasing the performance of your sniper rifle. The AirsoftPro cylinder is made of a stainless steel seamless tube with a smooth inner surface. The bolt handle pin is also made of stainless steel, firmly screwed into the tube and laser welded around its entire circumference. This creates a perfectly strong connection. The cylinder has an outer diameter of 22 mm and can be inserted into Well MB06 and MB13 series.  The inside diameter of the cylinder is 20 mm and you can use stock or any custom pistons. Including AirsoftPro. Weight 179g.
