CorBon has released a new line of rifle ammunition designed for self-defense and close quarters battle (CQB): the Urban Response. To learn more about this ammo line, take a look at this video.

Designed for an AR-15/M4 weapon system chambered in either .223 Rem and 5.56mm NATO, the CorBon Urban Response load boasts a 55-grain jacketed hollow point (JHP) bullet which travels at an impressive velocity of 2900 feet per second combined with an energy of 1027 foot-pounds. These lead core, thin jacket bullets are loaded using match-quality Lapua brass. CorBon test-fired this load with a 16-inch barrel, which resulted in 1/2″ groups at 100 yards. The penetration was 10″ in ballistic gelatin. The CorBon Urban Response is aptly named, as this load is designed for use in a variety of different self-defense or CQB situations, including urban areas such as subdivisions, apartment complexes, and mobile home parks.

This load is available for a manufacturer suggested retail price of $63.75. There are 50 rounds per box. See below for additional details.
