All Spring Air Rilfles are styled after some of the world's famous FIREARMS, our Spring Air Powered rifles are true to scale and easy to operate. How they work... Pull back the slide, just like the real firearm they are modeled after, to change the firing mechanism. Aim and fire. These models must be manually cocked each shot. Because of their maintenance free design and affordability, these are excellent entry level AirSoft guns for the hobby enthusiasts.
