Description
Type 0 Chrome Bore-Up cylinder
The cylinder is made of brass. It is chrome-plated and its interior is also polished. This has an effect on the function of the piston assembly, which is more efficient due to the lower coefficient of friction. The cylinder is suitable for the M4A1/SR16 and other replicas equipped with inner barrels from 360 mm to 450 mm in length. The cylinder has an enlarged diameter, which means that it can only be used with corresponding cylinder heads and pistons (bore-up)
