Winchester Lake City M193 5.56 NATO ammunition is the go-to choice for AR-15 shooters, whether you're zeroing at the range, training for precision, or stocking up for serious practice. This classic military-spec round delivers proven performance in a 55-grain full metal jacket configuration, loaded to 3270 fps—the same ballistics trusted by shooters for decades. The 300-round polymer ammo can keeps your supply organized, protected, and ready to grab when you head out.
Built on Winchester's Lake City brass, each cartridge is boxer-primed and non-corrosive, making it safe for your rifle and reloadable if you work up your own ammunition down the road. The full metal jacket bullet resists deformation and feeds reliably through any AR-platform rifle, delivering consistent shot-to-shot performance without the fuss. Whether you're running through a couple hundred rounds at the range or building up a working stock, M193 is affordable without cutting corners on quality.
This is volume ammunition for shooters who believe in trigger time. It's not match-grade precision ammo, and it's not designed to be—it's designed to work, shoot straight, and let you focus on your fundamentals. The polymer container is a bonus: it stacks neatly, protects the rounds from the elements, and won't rust or corrode like old steel cans.
