There are different roles and positions of soldiers on a battlefield. They assume different positions based on their assigned post which can be determined by the skill at what they are good really at. Some are designated to be as front liners while the others are reserved to assume and target a certain high leveled enemy. Those that are in the position to get a few of high officials from the other side are usually given the post of being a sniper.
Being a sniper entails a different kind of ammo. They usually take hold of a sniper rifle to get the job done.
Just like in the real battlefield and real war, in the world of Airsoft, snipers may assume the same position as that of the true soldiers that serve our government or snipers on the side of the coin, which is the enemy. Snipers should have a good sniper rifle. They should have something that is of high accuracy in its shooting which would get the job easier.
Airsoft sniper rifles may vary from each other. There are rifles that spring powered like the Well MB4403A L96 FPS-440 Spring Airsoft Sniper Rifle. Some are Automatic Electric Guns (AEGs), one example is the G&G M14 EGM014WWS FPS-310 Electric Airsoft Sniper Rifle. And there is also gas powered resembling the KJW KM1 FPS-620 Green Gas Airsoft Sniper Rifle. In choosing the best airsoft sniper rifle it is greatly influenced by your own preference in how you actually play in the battlefield plus the specs and quality of the sniper rifle.
