Manufactured by G\u0026amp;G Armament, it combines a lightweight polymer construction with a bearing system and ported face to support smooth, consistent gearbox operation.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-size: 12pt; line-height: 107%; font-family: Arial, sans-serif; color: black;\"\u003eThe ported piston head design allows air pressure to expand the piston head O-ring during the compression stroke, helping create an effective seal against the cylinder wall. A good air seal is essential for achieving consistent compression and dependable performance from your AEG.\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"font-size: 12pt; line-height: 107%; font-family: Arial, sans-serif; color: black;\"\u003eAn integrated bearing assembly allows the main spring to rotate more freely as it compresses and releases.
