FPS Softair CNC ERGAL Double O-Ring Ball Bearing Piston Head for AEG

If you're upgrading your AEG with reliability and performance in mind, the FPS Softair CNC ERGAL Double O-Ring Ball Bearing Piston Head for AEG should be an integral part! Made from precisely machined ERGAL 7075 aluminium, this double O-ring piston head promotes flawless air seal qualities, equipped with ball bearings to reduce rotational stress on both your piston and mainspring for a long lifespan of top-tier performance. Its ported design ensures the O-rings fill up any gap between the cylinder inner walls and the piston head, sending all generated air downrange for maximum consistency and, thus, accuracy. Compatibility-wise, this piston head fits V2/V3 gearbox-equipped AEGs, along with certain other designs which take V2/V3 compression group parts.
