{"product_id":"prowin-hop-up-chamber-m4","title":"Prowin Hop-Up Chamber for M4","description":"\u003cpre\u003e\u003cspan\u003eThe ProWin M4 \/ M16 CNC hop-up chamber is a major upgrade over the stock plastic or weak cast metal hop-up chamber in your AEG. Metal hop-up chambers are known for providing a better air seal against the AEG gearbox and feeding much more smoothly than plastic chambers. However, many cast metal hop-up chambers have weak points in the metal due to the casting process, but this issue is completely eliminated with the ProWin chamber. This hop-up chamber is fully CNC machined from aircraft-grade aluminum, meaning it is lightweight and durable, and the bright blue color gives your AEG a custom look.\n\nSpecifications:\nManufacturer: ProWin\nModel: CNC Hop-Up Chamber M4 \/ M16\nColor: Blue\nSize: Fits Marui-style M4\/M16 AEG\nPackage includes: one (1) hop-up chamber and parts\n\nFeatures:\nCNC construction\nImproved air seal\nLightweight and durable\u003c\/span\u003e\u003c\/pre\u003e","brand":"Prowin","offers":[{"title":"Default Title","offer_id":52551186612565,"sku":"SP-PROWIN-01","price":34.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1024\/3607\/7909\/files\/image_f89541fc-f692-41fe-8098-d173040920f7.jpg?v=1771968971","url":"https:\/\/www.skirmshop.es\/products\/prowin-hop-up-chamber-m4","provider":"Skirmshop Spain","version":"1.0","type":"link"}
