Pumping gives you more power: pneumatic guns use compressed air as a propellant. However, rather than being supplied from a pressurized cylinder, the air is compressed by the user, who pumps the gun several times. The first air rifles were manufactured way back in the 17th century, when they were used for hunting. But today’s users are not motivated by nostalgia. Present-day models are based on the very latest engineering standards. The advantage of pneumatic airguns is that they require no additional equipment. You just pump them a few times and you’re ready to shoot.
