This all-steel cylinder is designed for WELL MB4401, MB4402, MB4403, MB4406, MB4407, MB4408, and MB4409 sniper rifles equipped with an M4 bolt handle mounting screw. Compared to standard cylinders, it offers significantly greater resistance to the high stress generated by powerful upgrade springs. The cylinder is manufactured from a seamless steel tube, while the steel bolt handle mounting pin is securely welded at four points and then polished to ensure smooth bolt operation. The surface is protected by chemical blackening for corrosion resistance. Before ordering, we recommend checking the diameter of the bolt handle mounting screw, as older WELL models use an M3 screw.
Made from a durable seamless steel tube for maximum strength, even when using powerful upgrade springs.
The steel mounting pin is welded at four points, significantly increasing resistance against pull-out during cocking.
Manufactured in the Czech Republic using CNC machining for precise dimensions and smooth operation.
The blued surface protects the steel against corrosion. Regular lubrication is recommended for maximum service life.
Compatible only with newer WELL MB44xx rifles using an M4 bolt handle mounting screw.
