The US military gets most of its small arms ammunition from the Lake City Army Ammunition Plant, which is operated under contract by ATK. They are allowed to sell their excess production on the civilian market each year, and they do so under the Federal American Eagle brand.
I tested some American Eagle XM855 ammunition, which comes packaged in 20 round boxes inside a reusable ammo can. In total, there are 420 rounds in the can. I've shot thousands of rounds of this ammo in the past, and it's extremely reliable. I didn't have any malfunctions in any of the test rifles, and it was more than accurate enough for general shooting.
This ammo was originally designed and produced for military use, and has a number of features that set it apart from other ammo on the commercial market. At the rear of the case, a crimped primer helps reduce the chances of a blown primer causing malfunctions. Also, there's a sealant there to prevent moisture intrusion. There's also a sealant on the case mouth, and the cannelured bullet and crimped case mouth help prevent bullet setback in automatic rifles. In addition, the ammunition is tested to function in temperatures ranging from negative 40 to 125 degrees fahrenheit.
The projectile this ammunition is loaded with weighs 62 grains and is made of copper, steel, and lead. There is a steel penetrator located at the front of the bullet and a lead core at the rear. The steel is entirely covered by copper and won't harm the barrel of your rifle. While this ammo isn't exactly armor piercing, some ranges won't allow ammo that attracts a magnet for various reasons, so you should be aware of the steel in the bullet.
Because steel is less dense than lead, this 62 grain bullet is actually about as long as a 69 grain lead core bullet. This is good from an aerodynamic standpoint, because it will be flatter shooting and less affected by wind. However, you shouldn't try to shoot this ammo in a 1 in 12 or slower twist rate barrel. It works best from 1 in 7 or 1 in 9 rifles.
One thing you might notice about this ammo is the discoloration on the case mouth. It's the result of a heat treatment process called annealing, which prevents cracks and other case failures during manufacturing and beyond. The military requirements for this ammo state that the evidence of this process has to be left on the case, so that's why it isn't as shiny as other stuff on the market.
One final test I had for this ammo was to use a chronograph to measure the muzzle velocity. It met the standards that were set for it, which I expected.
Whether you're looking for good 5.56 ammo for range use or you want to put away a bunch of reliable ammo for a rainy day, Federal XM855 in a military ammo can is a good choice.

Great site for ammo!
I was totally surprised to find this ammo in stock at such a great price! I had been looking and everyone was out of stock. I'll be buying more and not just 5.56. So far every round has chambered flawlessly. Shipped quickly. Well packaged.
Lucky Gunner had it, when no one else did.
I had been looking for quality ammo for my new Colt AR, but could not find good ammo that would not break the bank. Finally I came across Lucky Gunner's site and I could not be happier with the quality ammo I bought at a decent price. It seems like everyone has run out of quality ammo or their price is outrageously high. I hope LG will have more in stock soon. Shipping was fast and the ammo can it came in makes it handy for transport or storage. Thanks from a new customer.
Definitely a must have for all AR-15 owners! Love the fact it comes in an easy carry ammo can, that keeps your ammo clean and safe. While I did notice an increase of about $20.00 for this particular product, luckygunner is not to blame. The price of ammo along with everything else food, gas etc is steadly on the rise. As always I am a loyal customer of luckygunner for their selection, prices and Super FAST shipping. Keep up the great work guys and gals!
The ammo can has a good rubber seal and the ammo is exactly what I expected. It has exceptional accuracy out of my AR-15. As for Luckygunner.com, the site is always reliable. I have made 5+ bulk ammo purchases and I couldn't ask for a better supplier. Fast delivery of the product I ordered every time.
Awesome!! ammo for the price
Let me first start off by saying that this is an awesome website to buy ammo from. This ammo was the first batch that I ran through my new Rock River Ar 15. I only had one jam out of the entire 420 rounds. The metal case was also a huge plus, as you can place other ammo for safe storage. The shipping was astronomically fast and well packed. I would most certainly buy more ammo from this website. ;)
