Winchester M193 5.56 NATO 55gr FMJ Ammo - 800 Rounds Value Pack

The Winchester USA M193 delivers military-specification performance in a high-volume value configuration. This 800-round case provides serious shooters with consistent 5.56x45mm NATO ammunition at an economical price point.

What Makes This Different

Winchester's M193 specification matches the original military load developed for the M16 platform, featuring a 55-grain full metal jacket projectile with a muzzle velocity of 3,165 fps from a 20-inch barrel. Unlike commercial .223 Remington loads, this NATO-spec ammunition generates higher chamber pressures and delivers enhanced terminal performance. The brass cases feature military-style crimped primers and consistent powder charges that meet stringent military accuracy standards.

Key Features

• Military M193 specification with 55-grain full metal jacket bullets
• Muzzle velocity of 3,165 fps from 20-inch barrel, 3,020 fps from 16-inch

This ammunition excels in high-volume training scenarios, competitive shooting disciplines, and tactical applications where consistent performance matters. The M193 load pattern delivers effective accuracy out to 500 yards while maintaining reliable function in both semi-automatic and full-automatic platforms. The full metal jacket construction ensures consistent feeding and extraction across various rifle configurations, from lightweight carbines to precision match rifles.
