The ASG SR-25 steel full seal cylinder is designed to provide maximum compression, with the least amount of resistance to the piston head. The cylinder is non-ported and is crafted from heat-treated steel with low resistance, making it the perfect cylinder for all SR-25 and LMG metal gearbox AEG style rifles.
