Laylax (Prometheus) – Hard Piston Next Gen Ver.2 (Marui Recoil)
This is almost certainly the best upgrade piston available for the TM Recoil M4/416/417 range of rifles, with 4 hardened steel reinforcement teeth as well as reinforcement along the remaining conventional polymer teeth, and even has the 1st-tooth removed to allow for correct piston engagement.
A highly recommended part for any upgraded TM Recoil M4/416/417!
