ZCI Aluminum Piston Head


These ZCI aluminum piston heads make the perfect addition weather your building a high velocity DMR or you just want a little more power and durability from a stock gun. These have a pretty classic piston head style including a 8 ball thrust bearing and have a good quality O-ring (no parting lines). These also come with a lock washer on the screw to help prevent piston head unthreading, while this will certainly help I would still recommend thread locker (loctite) just in case, you should always use thread locker on any piston head as it's fairly common for them to come unthreaded.

Note: Current stock is red instead of blue, color varies from order to order.
