The product does not constitute ballistic protection and has no other protective properties. It is not intended for use in protective purposes, including during tactical/war/ASG games.
The use of the product for ballistic protection and/or for other protective purposes, including the use during tactical/war/ASG games, is the use of the product contrary to its intended use, in which case the buyer does so solely at his own risk.
The vendor is not liable for damage to the product, that might result from the use of the product contrary to its intended purpose, this also applies to all possible health consequences (bodily harm) for the user (buyer) or damage to property. Moreover, a misuse of the product will void the warranty on the product.
The vendor is liable to the buyer under the warranty for product defects (in the event of such defects) only if the buyer/user uses the product for its intended purpose, i.e. for purposes other than protective purposes, including the use during tactical/war/ASG games.
The lack of any protective properties of the product is a feature, not a product defect, and therefore it does not constitute a physical defect of the product within the meaning of the Polish Civil Code.
JG/GE Hop-Up rubber
The hop-up rubber is made of rubber. It is adapted to be used in a system that is equipped with the main spring's characteristics up to the M130
What is the Hop-Up system?
The Hop-Up system is a system giving the BB pellet shot by airsoft replicas a spin movement. It uses the Magnus effect to flatten the trajectory of a flying bullet and, therefore, it makes it look similar to the trajectory of a real firearm’s bullet.
In reality, it is a properly shaped rubber or silicon seal that by touching a sped BB pellet gives it a rotation. The easiest way to explain what the Hop-Up system is to say that a BB pellet that is spun from one side generates more friction to the air so that it can turn. If the rotation will take place in the horizontal axis the BB pellet will turn upwards and compensate the force of gravitation.
The level of how strong the Hop-Up rubber touches the BB pellet determines how strong it will rotate and, therefore, go up. The heavier the BB pellets is the greater must be the pressure of the Hop-Up rubber ( while the heavier BB pellet has a greater inertia and falls down more quickly ). It works the other way around too – when a light BB pellet will be rotated to strongly it can go above the firing line.
