CORBON's Urban Response is the ideal self-defense rifle load for CQB-close quarter battle, urban environments such as subdivisions, apartment complexes, and mobile home parks. This is a rifle load that offers instant stopping power without over-penetration. Urban Response is crafted with the finest quality components, including match-quality Lapua brass. The bullets are designed with a thin jacket and a soft lead core, making it an extremely accurate and consistent load. With a velocity of 2900fps/Energy 1027 ft/lbs, it is compatible with all AR-15/M-4 rifles with either the 223 Rem or 5.56 NATO Chamber. This bullet does not expand in the traditional sense, but fragments to minimize over penetration in urban environments.
