UAC Enhanced Piston Head for Tokyo Marui M&P9 GBB

The original Tokyo Marui M&P9 was fun, but the parts would quickly wear down with the full automatic fire, and UAC seemed to have a solution to that weakness. The new Enhanced Piston Head for Tokyo Marui M&P9 is constructed with a high density polymer and will provide better air seal and durability to the piston that delivers superior performance when used with other UAC upgrade parts.
