The AA-9 HIKER (High-Impulse Kinetic Energy Round Weapon) is a shoulder-fired, burst-mode anti-armor weapon with unique design characteristics.
A single trigger-pull releases a rapid-fire burst of eight 12.7mm copper-core Penetrator slugs followed by a single 15.5mm round.
A single oversized cartridge houses all nine rounds in individual rifled chambers. The cartridge corkscrews backwards through the mechanism as each round fires in rapid sequence, with a friction-damping system absorbing most of the heavy recoil. The empty cartridge is ejected from the rear of the weapon over the user’s shoulder.
When aimed from the shoulder from a tightly-braced stance, all nine shots will typically group with a reasonable degree of accuracy and precision. The initial eight slugs successively penetrate even the toughest vehicle armor to cause massive internal secondary fragmentation, followed by the high-explosive round to deliver the final coup de grace.
