Magtech 5.56x45mm NATO 55 grain FMJ ammunition delivers reliable, mil-spec performance at the range or in the field. Built to Military specifications at CBC's Brazilian facility, this round mirrors the ballistics and construction of M193 service ammunition—making it a trusted choice for AR-15 owners, competitive shooters, and hunters who want consistent, affordable centerfire rifle rounds without compromise.
Each round features a 55 grain full metal jacket projectile seated in a sealed primer case, a combination that protects against moisture and extends storage life without sacrificing velocity or accuracy. Whether you're running drills, zeroing a new rifle, or stocking up for regular range sessions, this ammunition gives you the dependability of a military-standard load at a practical price point.
Magtech has built a reputation for consistent quality and value across their ammunition line, and this 5.56 load is no exception. The sealed primers mean less worry about environmental exposure during storage, and the mil-spec powder charge delivers the performance shooters expect from a proven platform.
