It performs perfectly in both typical conditions and negative temperatures – it retains its properties even at temperatures reaching 40 degrees below zero. \u003cbr\u003e\u003cbr\u003eThe Hop-Up bucking is adjusted to work in a system equipped with a main spring up to (and including) an M140 characteristic.\u003cbr\u003e\u003cbr\u003e   What is the Hop Up system?\u003cbr\u003e\u003cbr\u003eThe Hop-Up system is a system that gives the BB pellet fired from airsoft replicas a rotating motion. It uses the Magnus effect to flatten the trajectory of a flying projectile and, thus, makes it look similar to the trajectory of a real firearm bullet. \u003cbr\u003e\u003cbr\u003eIn reality, it is a suitably shaped rubber or silicone gasket that, by touching a BB pellet, gives it a spin. The easiest way to explain what the Hop-Up system is, is to say that a BB pellet that is spun from one side generates more air friction so that it can spin. If the rotation occurs on the horizontal axis, the BB pellet will spin upwards and compensate for the force of gravitation. \u003cbr\u003e\u003cbr\u003eThe level of force with which the Hop-Up bucking touches the BB pellet determines how strongly it will spin and, thus, rise. The heavier the BB pellet, the greater the pressure from the Hop-Up bucking must be (while a heavier BB pellet has greater inertia and falls faster). It also works the other way around: when a light BB pellet is spun forcefully, it can go over the line of fire.\u003cbr\u003e","brand":"G\u0026G","offers":[{"title":"UN","offer_id":62046186766666,"sku":"GIG-08-002665-00VERDE-UNI","price":7.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/8921\/4538\/files\/image_1c133fa6-cd2d-462a-8b64-2436f38c97d9.jpg?v=1780930739"},{"product_id":"g-g-g-g-set-gommino-hop-up-resistente-al-freddo-g10061-verde","title":"G\u0026G G\u0026G COLD-RESISTANT HOP-UP BUCKING SET","description":"G\u0026amp;G COLD RESISTANT HOP-UP BUCKING SET\u003cbr\u003e\u003cbr\u003eHOP-UP BUCKING\u003cbr\u003eRESISTANT TO LOW TEMPERATURES","brand":"G\u0026G","offers":[{"title":"UN","offer_id":62050618704202,"sku":"G10061VERDE-UNI","price":9.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/8921\/4538\/files\/CC---G_28_29G---G10061VERDE.jpg?v=1784839660"}],"url":"https:\/\/www.military-surplus.it\/en\/collections\/hop-up.oembed","provider":" MILITARYSURPLUS","version":"1.0","type":"link"}
