Frontier 5.56 Nato 55gr M193 FMJ Ammo 1,000 Rounds

The Frontier 5.56 NATO 55gr M193 FMJ Ammo delivers reliable, cost-effective training and practice ammunition trusted by law enforcement and military personnel worldwide. Designed for the AR-15 platform and compatible with most 5.56 NATO rifles, this full metal jacket round excels in high-volume shooting applications where consistent ballistics and dependable ignition are non-negotiable. Whether you're running qualification courses, maintaining proficiency at the range, or stockpiling duty-grade ammunition, the M193 specification has proven itself across decades of tactical operations.

The 55-grain projectile represents the original M193 military specification, delivering a velocity-to-mass ratio optimized for 1:12 twist barrels while maintaining inherent accuracy and minimal wind deflection at typical engagement distances. The full metal jacket construction protects the lead core, reducing fouling in suppressed systems and extending barrel life compared to hollow-point or soft-point alternatives. Hornady's quality control ensures consistent powder charges and primer seating, eliminating common reliability issues and delivering shot-to-shot velocity spreads tight enough for precision work and tight enough for combat-grade confidence.

Tactical operators, reserve and active-duty shooters, and competitive marksmen benefit most from bulk purchasing Frontier M193 ammunition for sustained training cycles and emergency readiness stockpiles. This load cycles reliably in direct impingement and piston-driven AR platforms, suppressed and unsuppressed configurations, and functions flawlessly through most aftermarket bolt carriers and buffer systems. The 1,000-round case purchase option reduces per-round cost while ensuring you maintain adequate inventory for extended qualification cycles, transition drills, and live-fire tactical scenarios without interruption.
