The MEC R-Type KWA-14 is engineered as a definitive drop-in fix. Weighing 2.5g and crafted from CNC brass, it features a 6-port flow system that instantly converts raw gas pressure into a uniform radial seal, flattening out your FPS curve and keeping cycles smooth.\u003c\/p\u003e\n\u003ch5\u003eKey Features \u0026amp; Benefits\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eResolves KWA Nozzle Binding: The rigid brass core cannot swell or deform like stock rubber components, ensuring long-term dimension stability.\u003c\/li\u003e\n\u003cli\u003e6-Hole Radial Direct Flow: Evenly distributes incoming gas to expand the seal in microseconds, containing blowback force where it belongs.\u003c\/li\u003e\n\u003cli\u003eTolerance Adjuster O-Rings: Packaged with red, black, and green O-rings of micro-varying tolerances to allow tactical gunsmiths to achieve the perfect balance of slide speed and compression.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eTechnical Highlights\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 2.5g\u003c\/li\u003e\n\u003cli\u003eMaterials: Precision-Cut Brass, Heavy-Duty Rubber\u003c\/li\u003e\n\u003cli\u003eCompatibility: KWA TT-33, M9, M93R, MP7 GBB\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cp\u003eSustained Full-Auto Suppression: Prevents dramatic gas drops during full-auto bursts on platforms like the MP7 or M93R.\u003c\/p\u003e","brand":"MEC","offers":[{"title":"Default Title","offer_id":41455220719806,"sku":"ME104490300","price":70.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0592\/0368\/2494\/products\/original_5abdd82a-5cc6-4315-88ac-cfa70fead543.jpg?v=1756090123","url":"https:\/\/pts-steelshop.com\/products\/mec-r-type-piston-head-kwa-14-kwa-mp7","provider":"PTS Steel Shop","version":"1.0","type":"link"}
