Century Arms MKE 5.56 NATO ammunition delivers military-spec M855 performance with 62-grain full metal jacket projectiles featuring a steel penetrator core. Manufactured to NATO specifications, this green-tip ammunition is well-suited for high-volume training, defensive applications, and duty use where barrier penetration is a consideration. The SS109-equivalent projectile design offers consistent accuracy and reliable feeding in ARs and other 5.56 NATO chambered rifles.

This bulk case contains 75 boxes of 30 rounds each (2,250 rounds total), packaged for volume shooters and armories. The ammunition is brass-cased and Boxer-primed for potential reloadability.
