Ammo Overview

Quantity - 300 rounds loose packed
Manufacturer - Federal
Bullets - 62 grain full metal jacket (FMJ) XM855 steel tip
Casings - Boxer-primed brass


The 5.56 got its start is a military round, but it didn’t take long for the round to become immensely popular on the civilian market, largely thanks to the AR-15. After all, what’s more fun than slinging lead down-range with an AR-15? Your AR-15 is a great tool for tactical training and hunting both, and if you want to become a more proficient marksman and a more successful hunter, you need to get some range time in. One of the mistakes some shooters make is using cheaply made, poor quality ammo during range time; what you load your gun with matters, not only for performance sake but also for the life of your rifle.

At 62 grain these are lightweight rounds for the 5.56 cartridge but standard weight for Penetrator rounds; that’s right, these are the always-popular green-tipped XM855 Penetrators. These are Full Metal Jacket, FMJ, rounds, and as such do not expand on impact but simply punch through targets and keep going. These rounds have a steel core, giving them the ability to penetrate steel plates and other fairly substantial targets, but they are not armor-piercing rounds. Each round has a muzzle velocity of 3025 feet per second and strikes targets with truly compelling force. This ammunition is great for target practice and tactical training.

When you order this box of Penetrators from Federal you get 300 rounds. That means a fantastic weekend with your favorite rifle – or you could buy multiple boxes and spend serious time punching holes in stationary targets. Federal has been manufacturing ammunition since 1922 at their plant in Anoka, Minnesota. All ammunition undergoes extensive tests and strict quality control measures. If you’ve never put Penetrator rounds through your rifle, it’s high time you did, and if you have that means you already know how great they are. Order now and harness the power of the XM855 with your rifle.

A: Hello Chris, These 62gr. XM 855 FMJ rounds by Federal in 5.56 have brass cases, but they do have steel in the tips of the projectiles, so they will not pass a magnet test and are not allowed on some ranges.

A: Hi Zachary, The XM855 rounds in 5.56 are not considered armor piercing, but they do have increased penetration over the XM193 rounds as they have steel in the tip. Because of this, many ranges do not allow them to be fired there as there is a potential for damage to the backstop and ricochets.

A: No, this ammo is factory new from the Lake City Army Ammunition Plant. It is high quality ammunition.
