The world’s most fun air archery gun just got more–More Velocity, More Power, More Air! The Umarex AirJavelin Pro adds pro-level features to the original AirJavelin platform to create a compact, lightweight, and surprisingly powerful pneumatic arrow launching device. The AirJavelin Pro is powered by an onboard 7.4 cubic inch tank that accepts a maximum fill volume of 4,500 psi. This tank is regulated at 1,500 psi which leaves 25 effective shots. Expect 15 full power shots before the pressure drops below the regulator limit. Arrows will launch at 370 FPS and generate 52 ft-lbs of energy. No fill probe is needed as the tank is fitted with a male Foster-style quick connect fitting on the end and optics can be attached to the generous Picatinny rail section on top of the gun. M-LOK accessories are also easily attached to the M-LOK slots found on either side of the barrel.
