This small block of AABC took direct, concentrated, close-range fire in its center from the 35 (now spent) .50 cal. BMG shells shown, on top of previous test fire. The projectiles in this test were easily contained, stopped safely at a depth of about 6" in the material. This block would easily absorb thousands of additional .50 cal. BMG rounds, fully protecting the persons and facilities behind. In front, for comparison, is a .50 cal. BMG next to a .30/06 cartridge, which is dwarfed. One .50 cal. BMG round carries approximately 6.5 tons of energy at close range.

Nine .45 cal. bullets were fired one after another into a single point on a piece of AABC, resulting in the “back-stacking” shown above.

The 6” thick piece of AABC above protected successfully protected against the blast from 6.5 lbs. of military dynamite in direct contact, an explosion that replicates the force of a direct strike of a rocket-propelled grenade.

The 12" block of AABC above has safely absorbed well over 5,000 rounds from various firearms, including 2,500 rounds of M-16 armor piercing, 2,500 rounds of AK-47 armor piercing, many rounds from a .30 cal. belt-fed machine gun, some 12-gauge shotgun slugs and others.  The block remains just as viable for protection as it was before the first round was fired.
