About 5.56 NATO Ammunition
5.56x45mm NATO is the military-standard rifle cartridge used by U.S. and allied forces, and the round most AR-15s are optimized to shoot. Loaded to higher chamber pressure than .223 Remington, 5.56 delivers flatter trajectories and more reliable terminal performance, though it should only be fired in rifles rated for it. Expect bulk 5.56 FMJ — often 55gr M193 or 62gr M855 — to cost $0.40 to $0.55 per round. Kilo Tango searches live 5.56 NATO prices from Lucky Gunner, Ammunition Depot, OpticsPlanet, Guns.com, and Sportsman's Guide to surface the best bulk deals.
