Winchester USA M193 5.56 NATO 55gr FMJ Ammo 840 Rounds 2-Can Pack

The Winchester USA M193 5.56x45mm NATO ammunition delivers consistent performance for training, competition, and tactical applications. This bulk pack contains 840 rounds split between two sealed metal cans, providing reliable storage and field-ready portability for high-volume shooters.

What Makes This Different

Winchester's M193 specification ammunition meets NATO standards for velocity and pressure, ensuring reliable cycling in both 5.56 NATO and .223 Remington chambers. The 55-grain full metal jacket projectile achieves a muzzle velocity of 3,240 feet per second, matching military specifications for consistent ballistic performance. Unlike commercial .223 loads, this ammunition maintains the higher pressure standards required for reliable function in carbine-length gas systems and short-barreled rifles.
