Aguila, 5.56x45mm NATO, Full Metal Jacket Boat Tail, 55 Grain, 300 Rounds

The Aguila 5.56 55 gr. FMJBT series gives shooters a high-velocity, consistent round that's built for range sessions and precision target work, with a 55-grain full metal jacket boat tail projectile launching at 3260 fps for 1298 ft—lbs of muzzle energy to deliver the ballistic performance long-range shooters demand; the brass-cased 5.56x45mm NATO ammunition from Aguila, made in the United States, offers reliable feeding and extraction for semi-auto platforms and surplus-style rifles while the boat-tail profile promotes stable flight and tighter groupings at extended distances, making it an excellent choice for competitive practice, training, and high-volume target drills. This round carries ORMD/flammable transport considerations and HazAir designation for shipping awareness, and its straightforward FMJBT construction keeps velocity and trajectory predictable shot to shot, which helps shooters tune sights and wind calls faster. If you're stocking up for range days, zeroing, or building consistency behind the trigger, the Aguila 5.56 55 gr FMJBT delivers the accuracy, ballistics, and reliability you'll rely on.
