Winchester USA Valor M193 5.56 NATO 55gr FMJ Ammo - 125rd Box

The Winchester USA Valor M193 delivers consistent performance with military-specification 5.56x45mm NATO ammunition designed for high-volume training and tactical applications. This 55-grain full metal jacket round meets M193 ball specifications, providing reliable feeding and extraction across AR-15 platforms and military rifles.

What Makes This Different

Winchester's USA Valor line uses Lake City brass cases and military-grade components to ensure consistent velocities and reliable ignition. The M193 specification delivers approximately 3,240 fps muzzle velocity from a 20-inch barrel, matching military performance standards. Unlike commercial .223 Remington loads, this 5.56 NATO ammunition generates higher chamber pressures for enhanced reliability in semi-automatic rifles.

Key Features

• 55-grain full metal jacket bullet with boat-tail design for improved ballistics
• Lake City brass cases with boxer primers for reliable reloading potential
• M193 ball specification meets military accuracy and velocity standards
• Non-corrosive, non-mercuric primers ensure consistent ignition

This ammunition performs reliably across temperature extremes and feeding conditions encountered in competitive shooting and tactical training. The 55-grain projectile stabilizes effectively in 1:7, 1:8, and 1:9 twist rates commonly found in AR-15 barrels. Range officers and instructors frequently specify M193 ammunition for its consistent performance and reduced barrel wear compared to steel-core alternatives.
