The Umarex AirJavelin CO2 Air Arrow Rifle is a new way to shoot arrows. Powered by CO2, the Umarex Air Javelin launches a 170-grain air bolt at 300 fps. The AirJavelin takes airpower into a new direction with 34-foot pounds of energy delivered via Straight Flight Technology arrows. Shooters can line up the target with the installed open sights or zero in a dot sight or scope for pin-point arrow placement. The AirJavelin has a full-length Picatinny rail on the top along with a short section below the barrel. Both sides of the AirJavelin's stock are also equipped with M-LOK slots. The AirJavelin accepts 88-gram CO2 tanks and will launch dozens of arrows downrange on a single tank. The Umarex 2x12g CO2 adapter (not included) will also install on the AirJavelin handy for shorter shooting sessions. Lightweight and versatile, the Umarex AirJavelin is more than a new way to shoot arrows, it is a great way to open up archery fun for the whole family.
