The Remington Ultimate Defense Rifle Ammo in .223 Rem is a centerfire round built for shooters who demand reliable performance in defensive and duty scenarios. Loaded to 3100 feet per second with a 62-grain soft point projectile, this ammunition pairs proven bullet construction with a velocity designed to perform across typical engagement distances. Remington backs this load with their Core-Lokt Ultra bonded bullet technology—a lead core metallurgically adhered to a progressively tapered jacket that resists separation under stress. This design helps maintain bullet integrity and weight retention through intermediate barriers and various shooting media, supporting the controlled expansion characteristics you need when it counts.
Whether you're stocking up for personal defense, duty use, or serious practice with an AR-15 or other .223 platform, this ammunition delivers the consistency you expect from one of America's most recognized ammunition makers. The 20-round box format makes it easy to grab for range sessions or keep on hand for defensive readiness. Each round is manufactured to Remington's quality standards, so you can load with confidence in reliability and performance.
Ultimate Defense ammunition represents Remington's commitment to engineering rounds that perform reliably in real-world conditions. The combination of Core-Lokt Ultra bonding, appropriate velocity, and proven bullet design makes this a straightforward choice for shooters who prioritize dependable function and consistent results.
