Fiocchi 556M193L 5.56 NATO 55gr FMJ-BT Ammunition 50rd Box

The Fiocchi 556M193L delivers consistent military-specification performance with 55-grain full metal jacket boat tail projectiles engineered for reliable feeding and accuracy. This M193-spec ammunition meets NATO standards for velocity and pressure, making it suitable for both training and tactical applications across AR-15 platforms and other 5.56 NATO chambers.

What Makes This Different

Fiocchi's precision manufacturing process ensures consistent powder charges and bullet seating depths that translate to tighter groups downrange. The boat tail design reduces drag coefficient compared to flat-base bullets, maintaining velocity at extended ranges. Each cartridge undergoes quality control testing to verify compliance with SAAMI and NATO specifications for chamber pressure and muzzle velocity.
