This massively reduces the amount of friction on the nozzle movement during blowback, while still maintaining an excellent seal thanks to using 2 O-rings instead of 1. This reduces the dependency on heavy lubrication of the piston, and allows lubricant to get trapped between the 2 rings instead of escaping the cylinder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble-Ported. \u003c\/strong\u003eThe V2 piston features both traditional front-face ports and internal ports that connect together behind both O-rings to still provide some of that tried-and-tested O-ring pressure sealing that was the defining feature of the V1 KF piston and many other ported airsoft pistons.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt like a tank! \u003c\/strong\u003eThe re-design of the front face and O-ring grooves means that all weak points have been removed from the design.

The V2 design actually comes out weighing almost exactly the same as the V1 (around 10g\/0.35oz). The spiral grooves just make it obvious you've got a RW piston without the need for additional laser engraving.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWe still recommend wrapping the tail of the piston in a couple layers of thin PTFE tape, just to seal the return spring pin in place, and stop the piston rattling around at all in the bolt carrier. The gun will still work without PTFE tape, we just recommend it.
