While compressed gas HPA was once the standard mechanism for airsoft, this has mostly given way to battery-powered AEGs. Despite the rise of electrically powered airsoft rifles, there are still brands producing high-quality HPA airsoft rifles. These modern HPA airsoft guns offer far more power and control compared to the pre-AEG gas guns. With an HPA rifle, you get an accurate shot and you can easily adjust your gun’s power and rate of fire. They also offer a realistic recoil, making them extremely fun to shoot.
