Federal American Eagle 5.56mm ammunition is a straightforward choice for shooters who want dependable, budget-friendly rounds for the range. Built around a 55-grain full metal jacket bullet and loaded to 3165 fps, this is the kind of workhorse ammo that lets you focus on technique rather than flinching at the cost per round. Whether you're zeroing a new AR, running drills, or just putting rounds downrange to stay sharp, American Eagle delivers the consistency you need without the premium price tag.

Each box contains 20 rounds of reloadable brass-cased ammunition, so if you're invested in handloading, you're not burning money on once-fired steel.
