The Magtech 556B Tactical/Training 5.56x45mm NATO round delivers reliable, cost-effective ammunition for shooters who want dependable performance without the premium price tag. Built to SAAMI specifications with factory brass casings and a 62-grain full metal jacket projectile, this 50-round box is purpose-built for range time, training drills, and tactical practice where volume and consistency matter.
