The Umarex AirJavelin Airgun Rifle is a new way to shoot arrows! Powered by CO2, it launches a 170-grain air bolt at 300 fps and takes airpower into a new direction with 34 ft-lbs 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 stock are also equipped with M-LOK slots. It accepts 88-gram CO2 tanks and will launch dozens of arrows downrange on a single tank. The Umarex 2x12g CO2 adapter (01 UM2843) will also install on the it, which is 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!
