The all new Umarex Air Javelin Pro is a high pressure air version of the original CO2 powered Javelin. The Pro fills to 4500 psi and slings airbolts at speeds over 300fps regulated at 1,500 psi and over 20 usable shots this compact lightweight little arrowgun packs a punch. We take the Javelin Pro out to the woods on a deer hunt during Virginia’s early muzzleloader season.
