This spring is constructed from durable steel specifically to replace the original factory part when it becomes worn or fatigued from regular use.\u003cbr\u003eThis is strictly a maintenance and restoration component. It offers no performance enhancement, upgrade features, or modification to the rifle's cycling characteristics. The spring does not increase rate of fire, alter recoil impulse, or change gas efficiency from factory specifications. It simply restores the original operational performance exactly as the rifle functioned when new.\u003cbr\u003eOver time, the constant compression and expansion cycles experienced by buffer springs in GBB systems lead to material fatigue. When the original spring weakens, users may experience inconsistent bolt carrier group travel, feeding problems, or decreased gas efficiency. Installing this steel replacement eliminates these issues by returning the buffer system to its designed factory specifications.\u003cbr\u003eThe steel construction ensures longevity and resistance to deformation under the high-stress environment of gas blow back operation. It withstands repeated cycling without premature wear, making it suitable for regular skirmishers and intensive use. The spring fits directly into the buffer tube without any modification required, matching the exact dimensions and tension of the original parts it replaces.\u003cbr\u003eThis component is ideal for purists who wish to preserve the stock shooting experience of their VFC rifles. For VFC MK18 and KS-1 owners seeking to keep their rifles operating in peak mechanical condition, this steel buffer spring provides the simplest and most direct solution.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003ch3\u003e\u003cb\u003eKey Feature\u003c\/b\u003e\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSteel Construction Airsoft Spring\u003c\/li\u003e\n\u003cli\u003eDesign For Replace the Original parts (MK18 Part # 04-04, KS-1 Part # 04-47)\u003c\/li\u003e\n\u003cli\u003eSuitable For M4 Gas Blow Back GBB Airsoft Rifle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VFC","offers":[{"title":"Default Title","offer_id":47930624803044,"sku":"VG20SPG034","price":3.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0617\/1325\/2580\/files\/VG20SPG034-1e.jpg?v=1771574026","url":"https:\/\/www.ehobbyasia.com\/products\/vfc-buffer-spring-for-m4-gbb-airsoft-mk18-part-04-04-ks-1-part-04-47","provider":"eHobbyAsia","version":"1.0","type":"link"}
