| All most every Airsoft player knows about hop-ups | | | | If I told you the Bernoulli's Principle is related to using |
| but there are a few players that don't. If you have no | | | | hop-up would you believe me? Well if you have no |
| idea what a hop-up is then here a simple definition. | | | | idea what the Bernoulli's Principle is then in basic term it |
| Hop-up is basically the velocity of an airsoft BB when | | | | states that "an increase in velocity occurs |
| it's fired from an airsoft rifle. When an airsoft sniper rifle | | | | simultaneously with the decrease of pressure or a |
| has an adjustable hop-up, that means you can adjust | | | | change in the gravitational potential energy." |
| the speed or increase the speed of the BB firing from | | | | But how those this applies to Airsoft? Pressure is |
| the rifle. Hop-up is also the theory of backspin, in which | | | | inversely proportional to velocity, in that lower pressure |
| it usually spin in a up and backward direction. This is | | | | equals higher velocity. So in a spin-less BB being fired |
| cause by the BB grinding along the top of the inside of | | | | from a sniper rifle will have an equal pressure around |
| the sniper rifles barrel. This grinding of the BB causes | | | | the BB, but if a BB with a backspin creates a |
| friction and gives it a spin, that spin offsets things such | | | | difference in pressure on the opposite sides of the BB |
| as gravity and air resistance, allowing the BB to travel | | | | and this difference in pressure makes the BB travel |
| further. | | | | further. |
| These hop-up devices are used on airsoft sniper rifles | | | | So you can see, by adding an extra backspin to the |
| to apply more backspin to the BB. As stated earlier, | | | | BB, the accuracy of an airsoft rifle can be greatly |
| the backspin allows the BB to fly farther and stay in | | | | increased. That is why it is wise to purchase an airsoft |
| the air longer. There a also other things to consider like | | | | sniper rifle with an adjustable hop-up, so you have |
| for instance the wind and throw the trajectory of the | | | | greater control over where your BB's end up or whom |
| BB off to the right or left depending on how strong the | | | | it hits. Having this extra range in your shot will greatly |
| breeze is. There are certain hop-ups to help counter | | | | improve your kill ratio in an Airsoft game. Knowing how |
| this affect on the BB and some hop-up are made | | | | a hop-up works can give you greater confidence, |
| especially for certain size BB to provide the best | | | | since you understand how the hop-up upgrade and |
| results. | | | | hop-up in general works. |
