Ammo Inc St 5.56 55gr M193 20/500

The Ammo Inc St 5.56 55gr M193 20/500 is a full-capacity surplus ammunition package designed for military, law enforcement, and precision rifle shooters who demand reliable, field-proven performance. This 500-round case (presented in 20-round boxes) replicates the ballistic profile of the iconic NATO M193 cartridge, delivering the velocity and trajectory characteristics that have made this round the standard for carbine and rifle training, qualification, and duty use across professional firearms operations.

Each round achieves a consistent 3,165 feet per second, propelling the 55-grain full metal jacket projectile with the flat trajectory and minimal wind drift required for accurate shooting at intermediate distances. The M193 configuration uses a copper-jacketed steel core design optimized for penetration and velocity retention, making it ideal for both target work and duty-rated applications where consistent point-of-impact is non-negotiable. Ammo Inc's Compete line emphasizes velocity, accuracy, and recoil management—the 55-grain profile balances these factors to deliver controllable recoil impulse while maintaining the energy signature expected from 5.56 NATO performance standards.

This ammunition is compatible with all standard 5.56 NATO chambers, including AR-15 platforms, military-issue M4/M16 carbines, and civilian equivalents. The 500-round bulk purchase model suits high-round-count training cycles, academy qualification events, and shooting ranges requiring consistent supply. Professional shooters, patrol units, and competition riflemen benefit from the cost-per-round efficiency without compromising on the ballistic predictability that mission-critical work demands. Store in a cool, dry environment to maintain powder integrity and ensure reliability across extended storage periods.
