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. AirJavelin arrows are engineered for strength sufficient to handle extremely high CO2 pressure.
