Built for players who want smoother cycling, stronger air seal and improved rate of fire, this is one of FPS’ most advanced piston head designs.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe \u003cstrong\u003efront‑facing ventilation ports\u003c\/strong\u003e expand the O‑ring during each shot, ensuring that every bit of air inside the cylinder is pushed forward to propel the BB — delivering tighter FPS consistency and better overall efficiency. The \u003cstrong\u003edouble O‑ring configuration\u003c\/strong\u003e further enhances sealing performance, especially in upgraded builds.\u003cbr\u003e\u003cbr\u003eThe integrated \u003cstrong\u003eball‑bearing system\u003c\/strong\u003e reduces spring tension during compression and release, helping maintain spring health and improving gearbox smoothness.
