Frontier FR2015 5.56 NATO 55gr FMJ Ammo - 150 Rounds Military Grade

The Frontier Cartridge FR2015 delivers consistent military-grade performance for high-volume shooting applications. This 5.56x45mm NATO ammunition features precision-manufactured 55-grain full metal jacket projectiles engineered for reliable feeding and consistent accuracy across multiple firearm platforms.

What Makes This Different

Frontier's military-grade manufacturing standards ensure each cartridge meets strict velocity and pressure specifications required for tactical and training applications. Unlike standard commercial ammunition, the FR2015 undergoes enhanced quality control testing to deliver the consistency demanded by law enforcement and competitive shooters. The brass cases are manufactured to military specifications for optimal extraction and reliability in semi-automatic rifles.

Key Features

• 55-grain full metal jacket bullets for consistent ballistic performance
• Military-grade brass cases manufactured to NATO specifications
