Cent Arms Mke 556nato 62gr 30/2250

Century Arms M855 5.56 NATO 62-grain ammunition delivers reliable, cost-effective training and duty rounds for military rifle platforms and law enforcement applications. Designed for shooters who demand consistent performance without premium pricing, this full metal jacket (FMJ) load cycles reliably through direct impingement and piston-driven platforms alike. Whether you're running qualification courses, zeroing optics, or maintaining readiness, the Century Arms M855 provides the ballistic consistency and case integrity that professionals depend on in high-round-count training environments.

The M855 round features a 62-grain projectile with full metal jacket construction and brass casing, optimized for barrier penetration and consistent velocity downrange. Loaded to NATO specifications, this ammunition maintains tight velocity spreads essential for accuracy validation and repeatable shot groups at intermediate distances. The heavier 62-grain bullet compared to standard 55-grain offerings provides marginally flatter trajectories and superior retention of velocity in crosswind conditions—a measurable advantage in field scenarios. Brass cases support reliable feeding and ejection across a broad spectrum of bolt carrier group tolerances, from mil-spec to enhanced platforms.

Law enforcement qualification ranges, reserve military units, and civilian shooters managing high-volume training schedules benefit most from bulk purchases of this ammunition. The 30-round box format integrates seamlessly with standard AR-pattern magazines, and the full case quantity of 2,250 rounds supports sustained training cycles without supply chain interruption. Compatible with any 5.56 NATO or .223 Remington chamber, the Century Arms M855 performs reliably across entry-level and duty-grade carbines, making it an economical baseline round for shooters prioritizing repeatability and availability over premium match-grade performance.
