Umarex ARX ammo incorporates patent-pending innovation that promises extreme hunting performance. The Umarex ARX SpeedBelt bullets are constructed from an advanced polymer-copper matrix in a design that acts as a force multiplier, simultaneously dispersing kinetic energy both forward and laterally. ARX non-expanding ammo provides maximum hydraulic displacement and terminal energy transfer to targets.
The polymer formulation of Umarex SpeedBelt sabots creates a powerful seal in barrel lands and grooves, blocking the passage of air to swiftly drive the projectile down the barrel. Upon exiting the muzzle, captive air pressure on the sabot forces release of the high velocity, lightweight ARX ammo, which maximizes momentum and delivers un-paralleled terminal performance on target.
