Sniper rifles are equipped with different systems. The most widely known systems are spring, gas and battery powered (AEG). Especially the spring and gas operated versions are suitable for modifications to gain more power and precision which is why they are popular. Also electric models can be modified, but this is usually at higher costs and with more effort. There are, however, across all systems models which have a very good shooting performance from factory. The product details reveal more.
The advantage of the spring system also lies in the fact that hardly any costs incur for supplies and consumables. Furthermore it can be used at any temperature without a loss in performance. A negative aspect can be the relatively strong repetition mechanism which is not the case with gas and AEG models. Electric versions also lead to low recurring costs but initially a battery and a charger must be purchased while gas-powered guns cause higher recurring costs due to the gas consumption.
Because of the long barrels Sniper Rifles have benefits comparing to other weapons so they can be used for longer distances (up to 80m). It is recommended to have an additional pistol or a small machine gun (M11, MP5K, etc.) on hand for close distances.
